Default 95 heating up

I have a 95 vette that is completley stock at idle you can watch temp gauge almost bury itself (260) the digital info center gauge will show in the 230's although the fan will start at approx 228 and cool the car to 217 the info center always states (cool) I have looked everwhere and can find no leaks.? Any Ideas Thanks Firedude 359

With the LT1/LT4 reverse-flow cooling system, it is normal for the digital gauge to reach the 220-230 degree mark. The fans kick in at about the 221 degree mark.
Most people are used to conventional flow cooling systems and have a "bird" when they see reverse-flow in action.

The analog guages in these cars are not accurate. At best, they are a "guesstament". As long as your primary fan(s) are coming on around 226 and the second around 236 according to the digital readout, your in good shape. I have a 92 and your 95 may have a 2 speed fan instead.

Allow me the opportunity to "Pay It Forward".

Contrary to what you may have been taught when learning to drive..... the best way to keep your 95 Vette running cooler is to ....... leave the AC on ..... The way the circuitry is set up....when ever the AC is on, both electric fans are running.

My digital guage was showing the coolent approaching the 230 mark & I was concerned because it's a DD in comuter traffic. I was given this advice several weeks ago and now the car never goes above 215 in the worst stop & go.

This is also a lot easier on you as well compared to turning on the heater full blast in an attempt to bleed off some of the engine heat.

If your reading is getting buried at 260deg, this is not normal!!!

are you running 50/50 H2O / Antifreeze?

Your thermostat may be broke and not opening all the way.

For more cooling efficiency, also check under the front of the car and look between your radiator and condensor for debris that gets sucked in from the road, like leaves, hay, pieces of styrofoam cups....etc etc...... This stuff will collect near the top of the radiator. I just cleaned mine on my '95, and it was full of junk!!

Default Same

Same on my 95 LT1 . The analog gauge is way off from the digital. It reads close to 260° when the digital gauge is at 235° . I just go by the digital gauge since I've fixed all that was broken.. Just turned out to be a bad relay in my HIGH/ LOW circuitry. the fans should both come on LOW at around 228° and HIGH at 238° or so. shut off at around 217°. With the bad relay, I had no Low speed so, my fans didn't come on at all until 238° with the A/C off.

Ditto to Mr. Peabody's suggestion about the A/C. I never noticed that mine will run up around 220°-228° in traffic if the A/C is off , but recently discovered it on a sunny day w/ the top off and A/C off. They do run warm , verry warm. I usually run my A/C alot here in NE Tex. so didn't realize the temps until now.

This is just part of it with these engines , but the analog guage I don't even pay attention too. ,As long as it comes back down once the temp is at normal cruising range. 195°-205°. on the digital guage... Good Luck with it .

my bad....sorry I did not pay close attention in taht you have a descrepency between your analog and digital readout. For sure the digital is more accurate....but do check for debris buildup between your radiator and condensor(near the top where they come together).
