Thread: Is there a better radiator for my td5

Thanks in advance Pete

Look on fleabay there are full alloy ones dont know if anyone has been game enough to try them yet more than likely from China

There are a couple of performance radiators/ intercoolers on the market, one being Allisport. Go to www.allisport.com I believe if fitting the performance intercooler, the ECU should be remapped? Anyway, there is another, similar product, can't remember its name. The intercoolers are wider, better made. Bob


edit, allisport claim their radiators have 35% better cooling

I took an old one to Aussie desert coolers and got them to make a new one with a bigger core and metal tanks several years ago
Any competent radiator shop could do this for not much more than the price od a replacement one

It'd be interesting to know if there is any performance benifit to the bigger radiator.

I mean the more cooling of more water in the radiator mean the water pump has to pump less and the fan clutch can slip more. Both leaving more power for the motor.

My brother drives B Doubles interstate. A trick he uses for more power on hills. For those that drive trucks will know the Horton fan (big engine fan) sucks a fair amount of power from the motor. These fans have a switch on the dash so they can be turned On or Auto. He will turn it on on the flat where he has power up his sleeve then flick it to auto at the bottom of the hill. That way when he needs all the power he can get to climb the hill he gets as much power as possible until the fan kicks in and takes a little bit more out. Just the differance in starting the hill with engine and water temp right on or a few degrees under.

If the water is cooler the engine needs less to maintain operating temperature so the thermostate will stay closed or not open as much.

I think you will find, the water pump is constant. Doesn't stop. Or slow down. Bob


edit- I should add, " in relation to the thermostat "
