TD42 high performance water pump feedback

[Bloodyaussie]

Some may have read my question asked about high performance water pumps for the TD42 and was met mostly with dont bother its not worth it...

Well I am happy to say that I fitted a JPC pump before my trip to South Australia and was towing a hard floor camper and was fully loaded.

To say that it was night and day is an understatement as my cars water temps were never troubled once at all... it got to the point where for the first time I stopped watching the gauge.

There is a very long and steep hill heading up the Western Highway that goes for may kilometers and trucks end up crawling up it by the time they get too the top and my temps never went past 86 degrees.

The very most my temps saw was 88 degrees and that on a very steep section and it was after I had just stopped for a short break so you get that initial rise.

On my trip I drove many K's including some hard beach driving with high rpm holding 2nd gear high range for long section of beach and winding hilly country including crossing the Grampians and not once did my temp gauge go past the 80's in temp.

Now I have gotten to know what my temps are like and with new hoses and radiator plus good clamps and a higher rated radiator cap my system is in very good condition and was tested recently but on those long hills temps would climb to 99 degrees no problem and being this is one of the coldest winters in a long time I knew I would not be happy come a long hot summer.

So my experience with this pump is 100% happy and I would recommend to anyone who is willing to pay the coin... mostly those that tow heavy loads.

I will report back truthfully with my experience mainly coming into this summer.

These pumps retail for $480... not cheap I know but cheaper than some others out there and much better than Patrolaparts one by a mile.

Cheers.

As I said very John bennettish, has to have 40% more flow over those pressed tin fans that most OE pumps use.
John would've die grinded that back surface smooth to stop any chance of cavitation, but Johns pumps were $600.
for part "A" and a further $600 for part "B".
Nothing worse than looking at the gauges all the time ,one more thing sorted by the look of things.

[Ben-e-boy]

Its good to hear you finally have some reliability.
How is the turbo and new tune etc

Cheers Ben... turbo is good and will go into that soon.

[Bigcol]

well, thats a very nice looking piece of kit

looks nothing like the "hi flow" one that was in my 4.2 - thats why I was under whelmed

good job

ok, so where do I get one??????????????

[Bloodyaussie]

I was going o see if I could work towards a forum discount...?

Going to see them today I think.

[Hodge]

Going to see them today I think.

Might see you there, gonna go see Mark my self.
I'd be keen on one of these personally, providing there is benefit on a stock td42i ? I know any bit of extra cooling on a td42 is good, but thought I'd ask.

[Winnie]

So you reckon it dropped your temps by about 10 degrees? That's a huge difference, awesome work.

[nissannewby]

So you reckon it dropped your temps by about 10 degrees? That's a huge difference, awesome work.

It hasnt dropped his temps at all. Just stabilised them. The thermostat still controls the temp.

99c isnt that bad either.

[billyj]

sounds like just what i need for my tb42et

[Bloodyaussie]

Just spoke to Mudski and sitting on 110kmh his car is sitting on 95 degrees.. Now is this because his car is putting out a lot more horse power?

On the highway mine sat on 83-87 degrees doing 110kmh towing a camper.

[Hodge]

Well you did have that pump BA, and isn't he in QLD, warmer weather ??

[nissannewby]

More power. Slightly different system. 95 degrees is ok. Nothing to worry about at 95.

Dont take my comments the wrong way jono. Its good you have seen an improvement from the dollars you have spent. If you went with one from another company down there I dont believe the results would have been anywhere near as good. Jpc have done a nice job on the impeller.

[Bloodyaussie]

Cheers Matt yes the main difference I think is under load or big big hills where it seems to have made things more stable.. yes I know 95 is not a problem with these cars but it was how quick mine would climb in the middle of winter on a snow trip hitting 100 at one point when no one else seem to have this.

Eric Mark has the same pump as me and when I was first driving on my holiday the temp was in its mid 20's and towing... Mark is experiencing the same temps I think but not towing?

In the end I am very happy with it performance and have no regrets.

Jpc have done a nice job on the impeller. fwiw the other company down here have been working on a new pump for the last 12 months from the states and is just about ready for testing on td42's.

Will be interesting to see results.

I'm happy your seeing improvements johno, something I've been considering for a long time myself!

Good to get real feedback.

[nissannewby]

Lets hope it's better than the last attempt.

[Bloodyaussie]

Managed to get my hands on a patrolapart pump today and it did not impress me...

I would rather a good pump made in japan for a bit over $130 than this for $250 exchange.

Just took the camper back to mattys and the drive is up the calder with a number of big hills.

The car did not go above 88 degrees and i travel the road semi often so this is one road i have a good idea of temps... normally without a trailer i get well into the high 90's on one of the really long hills so this is a massive difference.

The recovery time is also much faster.

The next hill the check is at ab's place. ..he knows the one.

was replaced with one that looks like N#2

but DAYAM, I'm loving the look of N#3

have to go check my money tree, and shake the leaves a bit to see if any falls out................

Most of the main customers come from the top end of WA, NT and places like that.

[threedogs]

Those other 2 look to me having seen john bennet water pumps
will create a lot of cavitation, The one BA has is the bee's knees and well worth the $$$
be it bit costly.
Is there a bleed screw on the back of the head on these 4.2's for air

[Bloodyaussie]

Ok here is another update.

I have just spent 2 days traveling the local region with some big hills and much warmer weather plus at one point was towing more than a tonne of wood on winding country roads.

I also climbed the hill near ab's place and everything has worked brilliantly.

The hottest it got was 91 but besides the big improvement on temps was the way it recovers after the big hills.. the temps come back down so fast and do not linger in the higher temps long at all.

I'll keep up the updates.

[OLY]

good work mate, thanks for posting up your results. very helpful!!

[Bloodyaussie]

Here is another update from my latest trip to Sth Australia towing a camper fully loaded.

Now I was near on 4 tonne all up and headed up the Western hwy with that very long hill near Melton with the temps never getting over 90.

Later in the day we were near Horsham where the outside temps were in their 40's and their was a head wind I was at one stage sitting on 115kmh (did not mean to) and the temps got to 97 and held until I got back down to 105kmh then the temps sat at 92.... and if I went down to 100kmh the temps dropped to below 90.

All temps held and never continued to climb and when driving through small towns the temps very quickly dropped to low 80's.. all this is disgusting heat and towing fully loaded.

The car handled everything with ease and was never bothered.

To say this is one of the best mods I have done is an understatement and can easily justify the price of the pump.

[Winnie]

That's awesome... Lots of people have troubles with the TD overheating so this mod should be pretty popular. How long have they been around?

[Bloodyaussie]

Not long... I think I was about the 5th or 6th car to run this pump and was a bit of a test dummy.

[Dannyboyz]

Hey mate just wondering what radiator and fan you are running with this pump? I am planning on upgrading the cooling system on my td42 as it is all standard and I am have alot of problems with it overheating while towing, hits 120 on the vdo gauge very quickly and takes forever to cool down again. Well aware that my system probably needs some TLC but I'm thinking that if I am pulling it all apart may aswell put it back together bigger and better!

[mudski]

He has the stock fan set up and i think a 3 core radiator..
I have one of these pumps in my gu. But everything else is stock.
My temps do get up around 105 to 110c when towing but they do drop fairly quick too.
I think for these motors its best to have bigger everything.

[Dannyboyz]

Thank you mate, that's what I am thinking, the troll has been so good and hasn't cost me a cent in six years (aside from usual wear and tear) so I think I should give it a birthday!

[mudski]

Yeah i think i need to update my system. Aussie Desert coolers are right around the corner from me but i have read too many horror stories of their rads cracking tanks etc etc.

[Dannyboyz]

Oh really? Thats good to know mate thanks! cos they are the only brand I ever hear about around home so I thought they were the go. I'm new to this forum so I guess I need to look around a bit more!

[Bloodyaussie]

Sorry mate I have been away in the high country..

My radiator is standard copper brass and good quality hoses with standard viscous fan, I have the complete shroud and a standard thermostat.

The only non standard is the pump..

Cooling system worked perfect on my latest trip with a heap of gear for 2 blokes camping for 4 days and some massive hill climbs that seem to go on forever.

[threedogs]

Norm and Aussie desert coolers what can I say GRrrrrrrrrrrrrrrrrrr
Norm knows his stuff but its let down by his product
better he sticks to Hot rods IMO never again

[Dannyboyz]

Cool mate, I have just had a proper look at your profile picture and see you have a GQ, I have a 98 GU wagon with an 03 td42ti under the bonnet, so radiators will be different anyway, I think I saw on another thread that factory GU rads are all alloy? Never mind the different models that water pump sounds a winner! I definitely have to do something with the cooling system on the big gurl cos I think regularly hitting 120 has got to be doing damage!

[Bloodyaussie]

Ok another update on this pump..

2 days ago i drove to murray bridge with a caravan weighing 2020kg and it was about 27 degrees as i left Melbourne up the western highway.

Now the climb up the highway is very steep and goes for bloody miles.

The temp got to its highest i have seen reaching 103 degrees but held and quickly came down again when leveled out or slowed down.. now i was still managing about 80kmh as i climbed the hill so was still pushing a bit and i could have gone faster if i wanted.

Once up the temps hovered around 92-98 degrees with the road rise and falling for another couple of hundred kms until i got near Ararat then things flattened out and temps would fall back well into the 80's.

The cooling system was never bothered the whole trip and am very impressed with how it has done to this date.

Now if it was a 40 degree day i would have probably crawled up that big hill and taken it a bit easier.

[Hodge]

As per Jonathans, description. I noticed the same change after my pump was fitted about 2 weeks ago now. How quickly the temps fall. Much faster compared to stock pump.

[BigRAWesty]

Did you only get to Murry bridge or did you go to Adelaide??
The free way out of Adelaide going up hill is a huge test..

So todays been the warmest day since I had the pump fitted. 29C up north where I was and I thought I'd tickle the car up the hills through Kinglake. Lugged it up a long hill in 5th, and it maxed out at 89, prior to that it'd be well into the 90's, even on lesser slopes...
Once again as per previous posts here, once over the hill and on flat/downhill ground the temps dropped very very fast into high 70's . Usually settles at 78-79.
So far so good.

[Hodge]

Why do you ask Andy? Is that your proving grounds or something lol.
Another test when going that was is after Whittlesea as the road winds it's way to the right and up.... That always forces down gearing.

Yarra Glen up to Christmas Hills is the favourite being steep and sharp corners to slow you down but from Dixons Creek up to Kinglake turn off on Melba is long and moderate steepness, pre IC I used to hit 500 + on that hill.

Towing was back to 3rd playing tennis watching the EGT gauge.

That hill is nothing. I can floor it on that hill and my egts wont go over 350c and water temp wont go over 100c. The hill up to Kinglake west from Whittlesea however....

How so? It would be good to compare water temps while both doing the same hill, same gear same speed etc etc i need to go bush. Lets go out Sunday, or something.

Just on top of this. If egts are that cool and water temps get to 100 then its the cooling system letting it get that hot not the extra fuel.

Hey mate. My JPC high flow is definite improvement over last summer in a sense , how much quicker the temps recover after car is pushed.
It hasn't helped lower the temps as such , but the recovery it's where the main difference is.
And i have a factory 2 core radiator. Original.
