c3 running warm?

Is this a normal temp range and is there something Im overlooking?.

============================================ That little 1 1/2 or 3 inch piece THAT YOU DO NOT HAVE will drop the temp at least 15 degrees......

Been there done that.... the foam insulation around the radiator / hood is also darn important....

overlooking?.

Because of the slanted mounting of the radiator, it's hard to get air to go through it. The front dam or scoop is mandatory. The foam around the radiator is mandatory. A good fan that pulling a lot of air is mandatory. My '77 runs at about 210 -215. It's a little nerve-wracking, but that's where it's normal. Fact is, the C3 seems to run pretty hot. There is an additive you can put in the radiator that helps it run cooler, too, but I can't think of the name of it right now. Maybe someone else can.

Larry OR Michele....

All the major vendors will have the air dam.... The radiator stuff is available I know from Dr Rebuild... Total cost for everything should be under 50 bucks...(???) or at least close...

My 79 came from the factory with the indy spoiler ...3 pieces...NOT one...

Over the years I have hit enough curbs that I have experience with 1 piece 2 piece and 3 piece indy spoilers...believe me 3 piece is the way to go....2 piece is ok...forget about the 1 piece spoiler...

Reasons above are all for ease of installation...

I am a lifetime member of the C3 registry...(C3vr.com) and although standard membership now will cost you 10 bucks you will get that back in good advice in no time flat...I suggest you whip out your visa card and start asking questions on all their forums....

spoiler..anyone

I have a full body kit on my '77. The front spoiler is one piece, but I stay away from curbs. It is large and scoops a lot of air. The difference between it and the regular spoiler is night and day. Fifteen degrees, easy.

Bob G. thanks for the info on the C3 club. I'm going to check it out, too.

hey isn't that called water wetter or something like that ?

I had the same problem on my 78 vette. Ran a little hot when I was at cruising speeds. I put a new clutch on the fan. (I could see fluid leaking from the fan clutch.) Solved my problem. I don't think air flows through the radiator at road speeds on my model without help from the fan. The air is drawn in from below and in front of the radiator.

Hi Larry,

My 77 had the very same symptoms when I bought it 14yrs ago. In fact I replace the same things you did. First the thermostat, water pump then the radiator. Still overheating. Only one thing left that I didn't change, the fans clutch. It figures with my luck the very last thing left to change in the cooling system was the one causing the overheat problems.

Hope this helps, Good Luck Tom
