Other than adding and oil cooler, is there anything that can be done to help a TR6 engine stay cool? I know that these cars are known for running hot. Any ideas?

I read somewhere that there is an issue with the crossover reference chart for TR-6 vs TR-7 thermostats. Some models require a "wiggle-pin" and others don't (and if you mix them up, it can cause a slightly higher engine temp in some models). Also, position of the bleed hole/wiggle pin makes a difference (for example, 12:00 vs, 6:00 in the opening). I'm not a Triumph guy (anymore), but I'd guess I saw this on VTR.ORG

BTW, in my car (an MG, but also in NJ) I usually run a 160 degree thermostat in Summer. Car deals with Friday afternoon Parkway traffic no problem.

Do you have an overheating problem, or are you just anticipating one? Cowling around the fan helps push or pull more air through. A chin spoiler creates a low pressure area behind it, which is below and behind the radiator, and pulls air away from the back of the rad.

Retarding the advance a couple of degrees may also help.

When these engines get hot, it helps to run the heater because the heater core is a small radiator. "Water wetter" claims to help, but maybe you hae a radiator that has some of its core, clogged up, so flush it. If yor drive in a hot climate, consider going to an aluminum radiator, they are available at racing dealers.

A raised lip in front of the louvers will also create a low pressure area behind it,drawing air from the engine compartment.

Rob,
Does your car still have the shroud in front of the radiator? They were originally made of a heavy cardboard like material that had a lifetime of about 3 rainstorms. I re-installed one on mine and my overheating problems went away, even in Southern California traffic.

I have replaced the shroud with a brand new one. I think that I will probably change to a 160 degree thermostat. I have had a TR7 and TR4A in the past that both had cooling problems, and I just don't want to have the same with my TR6 which I have spent the past 1.5 years making ready. I will add an oil cooler next winter when more funds are available.
