Interesting coolant temp
This is my first Corvette, a 1991, but I have noticed that it runs pretty hot unless I'm moving pretty good down the road. After reading some posts, I've come to the conclusion that it's normal. I don't think it ever gets above 220 or so, but it's right towards the high end of the gauge. Thats also running around town and not on the highway, cools fine there.
Anyway, what I found is that when I turn my A/C on while driving around town the coolant temp goes down several degrees. Is this normal or am I just seeing things? I thought that running the A/C would make it run hotter not cooler. Is there something I don't know? Mike |

Cool, thanks for the input, I learned something today:D

It's normal until you reach the temperature where your fan would kick on automatically. Then (in theory), the AC would make it run hotter. You might consider installing a 180* t-stat and programming your fan to kick in at 195*. If not, you're still okay.

You don't need to do anything.

It sounds normal. However, if you want to do some preventative measures. Check the air intake area for debris. In addition, you can check between the radiator and a/c. After a while leaves, street garbage, etc. build up in that area. It is a fairly straightforward to do, you can do it yourself, and doesn't cost you any money. Check other posts, some guys have pictures of what they found. Very interesting to say the least.

Thanks for the help guys, everything seems to be normal I guess. The radiator looks clean, no debris, so I'm just going to drive it:thumbs:

RACE ON!!! |
My 92 scared me first time in traffic but the LT1 was designed with the sole purpose of making you worry about over heating. Anyway I did a full flush on my radiator and got in there and really cleaned out the front debris and it runs about 10 below what it did before. What appeared to be a very well maintained car otherwise had been VERY neglected in the cooling department.
