Re: RUNNING HOT (B COOL LT4)
What kind of temps are you talking about. With the a/c on you should be around 200 - 205 degrees and with it off you should be around 225 to 230....Lots of owners think that the vette is running hot but they are designed to run hotter than other cars.

Re: RUNNING HOT (B COOL LT4)
250 is too hot. Pull the radiator and clean out the leaves and trash stuck in it. Flush the sytsem. Make sure both fans are on when the A/C is running. Pop in a new T-stat, it may be sticking. Make sure there is no air in the system. You might want to try a bottle water wetter as well.
Good luck

Nice to see someone else from SC :seeya
Best thing to do is remove your radiator and clean off the front of it, then flush and refill. Add a bottle of Water Wetter, and your temperatures should have dropped 10-20 degrees.
160 tstats work ok in SC, i run one in mine, no problems. So i would change it to a 160.
These cars are designed to run hot for emissions purposes, temperatures up to 235 are not abnormal. If the above suggestions dont fix it, the only permanent fix is to send your PCM off to be reprogrammed to make the fans come on earlier.

Re: RUNNING HOT (B COOL LT4)

Re: RUNNING HOT (B COOL LT4)
as noted above, remove the shielding from the top or your radiators - there's a dead zone between them that fills with debris - how so much junk can get in there is a mystery, but it does!

Re: RUNNING HOT (Alchemist)
Wow! My engine compartment looks really clean, I would be surprised to find all that, but I will give it a try. My AC blows cold, but not that cold...know what I mean? Might just need recharging, but Im gonna attempt to yank the radiator and clean it first. THanks for the advice... :cheers:

Re: RUNNING HOT (B COOL LT4)
The air intake acts like a vaccum cleaner on the highway. It will pick up leaves, bags, paper and just about anything that isn't tied or stuck to the road. When I cleaned mine I found a plastic grocery bag, hot dog wrappers, gum wrappers and leaves. Now I clean this area yearly if not more often.

Re: RUNNING HOT (B COOL LT4)
Had the same problem before, but that was after I put the 383 Stroker motor in. Almost went nuts! I had a BeCool radiator installed (at the same time as the motor), a 160 degree t-stat, had both fans come on at 190 degrees. Ended up needing to put in a high flow water pump. Worked like a charm. My temps usually sit around 200-210 while sitting in traffic in 90+ degree weather.
