Was changing thermostat on my 95lt1 when i noticed that they didnt look the same, after i did a search on the forum i understanded that it was a SB thermostat i got, and that the lt1 thermstat was a 2 way.
Can i use the thermo i got?
Is it anybody that uses the SB thermo?
What problem can i run into if i use it?

 

Do not use it.It is different for a reason.Not sure what it will do,maybe overheat.Use the right one!

 

Ok but i wont to know Why and what problem i can get.

I bought the thermo from Pcmforless when i bought my new/used pcm and i dont know if it has been a misstake our if he meant that i should use it. Have sent him an e-mail but havent got a answer yet and i want to get the car toghether as soon as possible

 

here is the problem you will encounter using a regular 160 thermo, I used one myself being the cheapskate and when idling the temp will RAPIDLY rise and almost overheat and it will only cool when driving over 2000 rpms

 

The regular SBC thermostat go in the intake manifold and are a part of a simple in/out flow arrangement.

The LT1 thermostat goes in the water pump, which has a complex arrangement of passages, routing coolant flow. The longer thermostat is made to work with these passages. When the thermostat is open, it seals off a passage below the thermostat. If that is not sealed, some of the heated coolant meant to go to the radiator will be sent back into the engine. Likewise some coolant from the radiator will not make it to the engine, either. Both of these things reduce cooling efficiency.

Some have used the old 160º thermostat and because of their particular setup (fan settings, driving habits, etc.) are able to get away with it. IMO, why risk overheating and head gasket failure for a few bucks and the correct themostat?

 

Yeah, what he said...

 

Hmmm.....not to disagree with anyone, but, I used a generic, off the shelf 160 thermo from AutoZone for the past 2 years, never had a problem with it and the car has never overheated, in fact, on a warm day, in traffic, the temperature gauge rarely exceeds 180. Just my .02

 

I think I have the same t-stat as you. I couldn't remember if it had the reverse-flow piece on it or not and haven't felt like taking it back out to see. I don't have a problem with overheating, but it does seem like it takes a little while for it to warm-up in the mornings.

 

Thanks for the answers
Shall wait and se what Bryan says about it.
