Thread: Puma Radiator Options

I'd be happy to order both an upgraded radiator and intercooler if PWR got on board.

Are you guys having heating issue's?,mines seen 50 plus degree's,my thermometer only goes to 50 and my coolant temp only got to 100 and that was fighting the dunes on the canning at wells 30 and up.I would look and airflow through the original,some gills at the rear of the front guards and no spotties etc at the front. Pat

I have had only slight overheating probs in heavy sand, but takes a while to derate. This is with no fan shroud. I would like to replace plastic radiator with aliminuim one with built-in electric fans to free up an acre of room under the bonnet. One day

I have big heating issues but then again I have a large intercooler, spotlights, portal axles, 35's and a performance chip........

I don't have any problems at low speed, deep sand etc, my problem come with trying to hold 100kph in 30kph headwinds uphill with a full 1000kg load, 33's, roof top tent etc when its 40-50 degrees.

I know I'm not quite where you are re mods, but I'm running a remap, big intercooler, 34 inch mud tyres, lifted, spotties and a winch solenoid box in front of the grill, and almost never go anywhere at much less than max gvm (lr fuel tank, 100 litres of water tanks, bar, winch, drawers, fridge, 2 spares, wheel carrier, dual bats, expedition rack, rtt, etc, etc, etc) and I have no heating issues at all (based on scanguage readings)?

I drive it hard enough to hold off the v8 cruisers and temp rarely exceeds 100 degrees - seems a little weird?

Seems very weird......

It's probably worth mentioning here that there are alternative coolant options that reduce operating temperature compared to normal glycol type coolants. Drops of 10-15 deg C are frequently reported, and in probably most cases would be all people need. (NB. I need to disclose here that we do on-sell one such product ourselves, but there are likely others as well that people could source.)

I'm not trying to flog product here, rather make people aware that if extreme operation is causing temperature problems (rather than cooling system defects), it may not be necessary to migrate to larger radiators.

With such products, you need to investigate if they provide all the necessary protection to components, and what you need to do, if you need antifreeze protection as well.
