TD42 water pumps... what would you be prepared to pay

[Bloodyaussie]

I have been doing some research into performance water pumps for the TD42 as they have a real cavatation issue and my 8 month old radiator has sprung a leak and will be replaced under warranty..

Now there are 3 mobs I know of (interested if there are more)

The first and not an option really as I have heard nothing but crap or average revues is the Patrolapart one for $249 that is a standard pump with a different impeller.

The second is a bloke in Lilydale who swears by his product that he mainly sell to the Top End and WA and mostly for rigs towing with a much bigger impeller and larger bearing but still a stock housing for $550

Third is a high performance mob who have been in the game for many many years and have a complete build with billet housing and a completely different impeller for $660.... this mob have built some of the quickest cars in the country and build many comp truck TD42's

Hmmmm....?????

Mate, I'm interested in your comment on the TD42 water pumps having real cavitation issues.
I recently purchased a Jap import TD42T engine that I'm guessing has around 100k on it. I was advised to remove the water pump to check the state of the timing cover as it's an indication of a badly worn engine.

Here's a pic of what it looked like. If I polished the alloy it would look like new..
There is really no sign of any cavitation problem there..

I bought an original Nissan water pump for it.

Not sure if you are asking me a question or not??

Are you talking about pitting in the gallery as this is not what I mean..

Just checked the spelling and it should read "cavitation"

And also Mark from JPC asked me to come down quickly so they could check something out as he had concerns my cooling system was pressurizing but I got the clean bill of health except for how my radiator is mounted plus it turns out me Copper/brass is Chinese....lol

I’m sure there is always room for improvement - at a cost. However with the TD42’s reputation for reliability & longevity it seems most unlikely to me that TD42’s have a 'real cavitation issue’. I could be wrong, but would have thought it would be ‘common knowledge’ if this were so. As I understand it (from a quick sqiz at google), in a diesel the most likely areas of cavitation damage is cylinder liners, heads & pump impellers. I didn’t find any mention of radiators specifically.

Is your car getting hot?

i think it would be more likely that the engine is earthing out through the coolant, this is unlikely but has happened. more likely a manufacturing issue.
just my 2 cents worth

Use a genuine one. Machine it so there is less clearance on the impeller. Have seen 3mm taken out to get the clearance at a respectable gap. Dont waste your money on those "performance" pumps.

You can get a new genuine one landed for about $70.

Trying to work out what you mean...

Jpc tested my car today and said my cooling system is perfect and no issue of the engine pressurizing the cooling and i was told to get rid of my Chinese copper/brass radiator which is breaking apart.

So new radiator is being made tomorrow and should be ready then if not Thursday.

The other radiator has a warranty and will pick the new one up on Friday and sell it.
I wish more gq owners used accurate temp gauges to compare with... i run a good digital job and find it much better than the dodge factory one.

Which bit.

Where do you do the machining??
