High Engine Temperature in Traffic - my solution. - ZR-1 Net Registry Forums

WARP TEN · 07-17-2017

I will certainly second getting Marc's chip. I had one in both my earlier '93 and my '95. Worked great to control temps. However, there is one thing you should not forget and perhaps check. The C4s are "bottom feeders", meaning they pull air for the radiator up from below the front nose of the car. As a result, they also pick up a lot of sand, dust, debris, leaves, etc. Overtime, the fins in the radiator become plugged. When I first had an overheating problem with the '93, with about 40k miles on it, I had the radiator pulled out and it about 40% clogged. (Marc said he once removed a radiator and got about 20 pounds of sane out of it) Hosed it out to clean all the fins. Then installed Marc's chip and it worked fine ever since. It is often difficult to really see if the radiator is clogged while installed (I know Marc has a way to view much of it) so it seemed best to just remove it when I ran into the problem. The '95 was low miles and was not clogged so I just had Marc install the chip. --bob
