Bigger water pump, worth it?

[AB]

Still looking for ideas on better water temps.

Heading up to krissos meet up on the Hume towing the camper, family and gear fully loaded in hot and humid weather saw temps within range but higher then I want climbing those long hills.

Hearing stories outside of forum of a bigger water pump.

Has anyone done this?

Does it work or will it just pump water faster around the system and not get a chance to cool properly through the radiator?

[Bloodyaussie]

How old is your radiator and when was it last cleaned inside and out?

Clean and fairly new 2 core from natrad after the love day trip mate.

[Bloodyaussie]

That was a while ago when did you last pull it out.

[nissannewby]

NO! Not worth it.

A very well known and respected company on the other forum did some testing and the "bigger" water pump made next to no difference.

That is all I will say here. You have my number if you want some info.

Last year gave it a blast and always anal about how clean it is.

Could do it again though and see.

Why so secretive??

[BigRAWesty]

What strength coolest blend??
I've used the more concentrated stuff and had no issues in early Jan when on the beach.

[Stropp]

ab what about the waterless coolant?? that is supposed to keep temps down

[Ben-e-boy]

You just need a bigger radiator, more capacity, if everything else in the cooling system is good, more capacity will help

[AB]

I'm running out of room at the front captain!

Is there any differences in sizing from the 2 core to 3?

Never tried that mate. Has anyone tried this before?

[BigRAWesty]

Usually a 3 core is usually 1/3 bigger than a 2 core.... ;-)

Only in thickness. My PWR fits straight in, holds another 5L+ of coolant

Not sure if it will fit with the condenser moved back 10mm. I reckon I have about 10mm left between them both now.

I just purchased the Tridon hi flow thermostat, I'll clean and flush the radiator, seal up the rubber where the ic piping goes under the guard and see how that all goes first. It's not critical high temps, towing a 1.5 tonne camper, car fully loaded with crap and all seats full with a hot and humid day up those long hills on the Hume saw the needle at 2/3 on big hills and once or twice got to 3/4 on those few km long steep hills.

coming back home was not even an issue. I think growlers gu got to 99 degrees on some of those hills too so it was a hectic day. As you might of seen in Johnos thread I sat 60 degrees lower then them (egt) so very happy with that considering growler wasn't towing and johno had a 6x4. I'll update my build thread after the hi flow goes in.

Don't quote me on it but I think the extra thickness would go towards the fan into the bay rather than towards the front of grill

Sounds right to me. As the radiator mounts to the rear of the support.

Thats exactly what I wanted to hear, cheers!!!

I'll see how the thermostat and cheap fixes go first...lol

There is also a product called "WETTER WATER" that coats the hard to get at places to allow water to get there.
what you want is a John Bennet water pump where he pulls out the factory press steel fan and fits an impellor.
Then uses a die grinder to smooth any area where cavitation appears, Increases water flow by 40%..
Have you called Craig davies about there electric fan

Do you have a link for these? Complete with thorough test rest results.

If you do install a bigger pump it would help heaps if you put a tripple pass in the radiator. I did this some years ago on a Toyota 4Runner when I changed the motor for a commodore V6, and it worked really well. I installed a Davis Craig electric pump that worked through the engine driven pump (in series in other words). I also installed a tripple pass which involved putting a block one third of the way along the top tank and the opposite in the bottom tank. Basically, the water enters the top tank, hits the block and flows into the bottom tank where it hits the bottom block. The water then flows up again into the top tank and lastly down and out the bottom tank (think of the water flow through the radiator as a back the front "N"). This solved all the overheating problems I had.

I think Norm at Aussie desert Coolers does that style radiator,
think he calls it his "outback" model

[Bloodyaussie]

Mark at JPC thinks that Aussie desert coolers are a load of shit.... Now dont shoot the messenger.

[liftlid]

Just about to take my radiator in for a flow check and clean will let you know what the verdict as I realised I did not flush it last year and now it's getting hot quicker than normal.
My rad bloke doesn't think 3 core cool better than 2 core but I'm unsure

From discussions I have had with people in the trade a good 2 core heavy duty radiator everyday of the week... now I think that suits most but I also think there would be exceptions to this being highly modified or towing excessive loads..

[nissannewby]

Read this. It will help answer a few of these questions. It goes into the amount of cores and their effect.

Lol. He's probably had a run in with Norm. If you have met him you'd understand why. But from what I have seen when I'm in there. Their products seem good to me. But I'm no eggspert....

Nothing wrong with the big "YID" would love to go to Lake Gardiner with him on the land speed weekends

[Bloodyaussie]

The more I think about it Andy the more I think your system is not to bad... I mean you have fitted 35's and had the car fully loaded and towing a heavy camper and traveling up some very very big hills that have trucks crawling up them.. Before you race out get yourself a decent gauge and actually find out what your temps are really doing.

I really like the gauge I purchased for $75 a couple of years ago but when I tried to look for it again it sold for much more.

I am not sure if unlike buying a cheap EGT gauge you can just get a cheap one or are they just crap?

Anyway just thinking....

Yeah it's not critical at all mate, just my usual paranoia kicking in.

Need to get a gauge pronto like you said.

[mudski]

I get along with him fine. You just gotta know how to take him...

As Jonathan said Andy. Get a gauge in to actually see what the temps are first. Then worry.

I was watching some yank show one day and they were testing different things to give more power to a motor and one of them was an electric powered water pump
yep type in electric water pump and you will see

Old stuff mate..... been around for a long time.

@ AB grab one of those thermo guns off Ebay for $15,
point it on the top tank and see what your oe gauge says.
Great tool for trouble shooting heating/cooling related problems.
Otherwise you are flying blind IMO

I've actually got one of those for the pizza oven ;)

I think you need to point yours at your head mate, all that dribbling must be causing some overheating issues with your noggin ........... Lolololololol
