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.
