I can't seem to find the correct 160 stat for my 08 Vortec Max. Please help. Exact part # and where to buy would really help.

 

Mr. Gasket 6367 - Mr. Gasket LS1 Thermostats - Overview - SummitRacing.com

 

Already tried that one didn't work, my stat and housing will not seperate.

 

Plus the water pump has special grooves where the stat goes thru,

 

In for the answer.

I want to do this too and haven't got to it yet.

 

No need to waste your money on it. Here in texas during the summer you are going to run 195 200 plus anyway because the cooling system cant reject enough heat in 90-115 degree weather for you to run any cooler regardless of the stat you put in it.

 

Anything newer than 04 will have a seperable thermostat housing and the link Cajun posted will be valid.

 

I've upgraded to a bigger radiator and it worked awesome, I just switched motors so the new motor still has the stock stat.

 

Might as well replace the water pump then. Any new pump you buy will only accept the 04+ thermostat design anyways.

 

Ttt..
