95 LT1 Cooling fans

[Jrick81]

My 95 I've recently replaced the radiator with a 3 core aluminum one replaced the high n low speed relays both fan sensors and my analog gage still gets up in the yellow when in traffic before the fans come on n the digital will read like 238 now I've been in the automotive trade too damn long to know that's a common temp that is to warm what can I do ne suggestions please now my 74 L82 used to run a little warm once I put in the aluminum radiator it dropped significantly

Could it be the thermostat? Would a lower temp one be better? Not sure.

If I remember right, that LT1 is reverse flow cooling and was prone to trapping air in the system. When I replaced the water pump on my old '95 Camaro, I think there was a process to follow to get all the air out of the system.

I replaced the thermostat with I Mr gasket high flow high performance 195'

Yes all u do is crack the bleeder valve once she is warm n the t-Stat opens

no I replaced it n a lower temp would only open at a lower temp not turn the fans om

Hello Jrick. I've been through the overheat thing, but mine is a stock L98 motor. What I've learned is a) lower thermostat not recommended, it messes with the CPUs mind. b) The cause of my problem was leaky head gaskets and once they were fixed, I replaced the rad. In town at slow running it still warms up, but I leave the AC on auto and the fans run full time, gauge never goes past half way.

Davee91Tm...
I know there is no head gasket issue I checked into all that before I done mechanical work for 17 yrs however it's just weird cause all the documents say these run 228 to tops of 238 n it just seems crazy watching once in a while that needle approach the yellow on warm days in traffic I just replaced all the a/c seals gonna give it a charge and see how she acts with both fans running cause in reality ur right there is nothing left to replace but head gaskets... Smh... I won't go cooler then the 195 t Stat but I did put a high flow high performance Mr gasket t Stat in it if u look them up u will c all the ports n much much bigger allows better flow...... Thank u for ur share though

I almost always have A/C on in my 93 (with three row aluminum rad) and that manages temperatures perfectly but I don't much enjoy the roar from the fans or the dust that is picked up from gravel parking lots.
Anyone tried SPAL fans or any other solutions to quiet things down?
