NEW Engine Coolant Thermostat GM 89018168 - AC Delco 131-160 OEM - 86°C / 187°F

Description

We build performance LS motors from the ground up, so when we get a new water pump for each motor the first thing we do is remove the stock 86 degree celsius thermostat and gasket. Then replace it with an aftermarket thermostat to fit our application, leaving these new unused stock ones that I'm selling here.
GM has changed their vender for thermostats and they are made in Japan now. If you message me I can try and get the style you want, but as you can see in the pictures other than saying, "Made in Japan" there is basically no difference.
Please look up your model on a GM Parts site for free to verify this is the one you need. I do not know all the applications for this thermostat as GM used it for many. This is from the water pump of a 2009 Base model Corvette with the 6.2L LS3 motor. The seal diameter is about 2.4" in the thermostat housing you need this one, but if the seal diameter is 2.3", then you would need the older smaller LS2 version.
I will only be selling inside the U.S.
No refunds for used returns.
