For this reason, we recommend using a minimum 180 degree thermostat and turning on the cooling fans at the 200-205 degree range. 1984 Corvettes will have the most noticeable improvement, as the factory cooling fan setting is 238 degrees. Lower temperatures will work at the expense of fuel mileage.
How fast is an 85 Corvette?
150-MPH
Yet so controlled that test drivers at the GM Proving Grounds felt secure, even at the 1985 Corvette’s 150-MPH maximum track speed, during long and arduous testing. No surprise when you consider Corvette’s advanced uniframe structure.
What temp should a LS3 run at?
Average coolant temp would be around 205-218F in normal driving around town. At freeway cruise speeds it should be around 195-210F. The fans on the LS2/LS7/LS3 are variable speed unlike the C5 which were on/off – Hi/Lo speed. The fan on the LS3 is on 15% at 199F and is full on by 225F.
Why does my Corvette run hot?
While there are a variety of reasons your Chevrolet Corvette is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
How hot should a 1994 Corvette run?
As for running temperatures: Running temps should be between 215-240. This thread is fulled to the brim with extremely valuable info. Make sure your radiator (both sides) is clear of debris. The C4 Corvettes are bottom breathers and are prone to collecting a lot of road debris over time.

What does a 160 degree thermostat do?
A 180-degree thermostat is better for engine efficiency—aka better fuel mileage and decreased emissions. A 160-degree thermostat is designed to maintain a lower engine operating temperature, which tends to make a little bit more horsepower and torque.
What is too hot for an LS engine?
Unlike first-generation OE electronically managed engines that didn’t go into “closed-loop” until coolant temps hit 195 degrees F, Rollings says GM LS engines typically go closed-loop around 160 degrees. Summit Racing is one source for a high-flow 160-degree LS thermostat (PN SUM-365-160).
What temperature does a engine overheat?
As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur. As heat continues to increase, the different rates of thermal expansion cause metal to distort.
What temp do you run your corvettes?
I would have to say most of us corvette owners want our cars to run at the same temp as the rest of the cars we own. For me that would be 200 to 210 degrees. My 1988 corvette has a 180 degree stat a hypertech chip that turns my primary on at 175 degrees and I have wired a bypass switch on my aux fan so I can turn it on any time I want.
What is the normal coolant temp range?
your coolant temp range is normal, (not ideal, but normal for a stock 1985 corvette) engine oil needs to reach and stay at about 215F-240f to lube and clean correctly and burn off moisture trans fluid I try to keep under 160F,surely below 180F,
Is 198 degrees too hot for engine oil?
Yes this is normal, Your LS engine is a very tight tolerance engine. It requires synthetic oil(5W-30) so that it will return to the pan fast enough to keep the pick-up sump from going dry.The engine makes more power and gets better mileage at 198-220 deg. This is fine, it is meant to run at this temp.
What is the normal engine temperature at 227 ECT?
At about 227 ECT the engine temp on the analog dash temperature reads up to 240-260 degrees. Just letting it idle in the driveway, the ECT hits 227 degrees and the engine temperature guage shows like 257 degrees and the fans turns on and the temp starts to drop.
