Replaced thermostat

[s65481]

I just replaced my stock thermostat with the MACE 82 degree thermostat

I took the old one out and put the new one in and bolted the housing to the block again
But there is water around the edges of the gasket when the car is on.

Do I need to replace the gasket or what would I need to do to stop it from leaking??

I put some gasket maker around the join but it still slowly builds up with water

Thank in advance

Hi all.

Its always a good idea to change the gasket aswell. I only use a little bit of sealant with the gasket....some guys dont.

what temp is the standard thremo stat?

bad idea changing it to a lower one.

I did a quick google search and found some interesting coments. See what you think: Pay particular attention to "Evil-Twin" He's meant to be a retired GM engineer who worked on the LS1 cooling system.

I would assume that a lower temp thermostat would make your engine run a bit cooler. These are designed to run at the factory temp. So don't know if it's a good idea to do what you've done?

Running a 10degree cooler thermo is quite acceptable. It will not mess with the tune or throw trouble codes at all.

Always replace a gasket when it is removed

Yeah a gasket costs a couple of bucks tops, so it is worth the time putting it in to save on the hasstle later.

From what I gathered from what 'evil twin' said was that the LS1 runs best in terms of performance and engine life between 82 to 92 degrees celcius.
Assuming that the Buick block has a bit more tolerance, you could say that the lower temp thermostat won't harm the engine too much.
'Evil twin' also said that he uses the lower temp thermostat during the warmer months of the year, so from this you could say that it would work best for your car during the warmer months, while the factory thermostat that is meant for your car, should be used in the cooler months of the year.

I too believe it is bad to thrash your car when it hasn't warmed up because it wears out your engine more and you don't get the same performance that you do with an engine at proper operating temperature.

82 degree thermostat in a ecotec is no problem at all.
