Hello,

The thermostat replacement is a simple 15 minute job. You will need to replace the coolant because the thermostat is located in the water neck. Two bolts and it's out though. I recommend 1 gallon coolant and 1 gallon Distilled Water along with 1 bottle water wetter. This alone kept our car's temps pretty consistent, the addition of the increased flow at lower temps with our thermostat kept our temps below 90 celsius, and shaved a tenth off our quarter mile.

It's a simple and worth while mod.

Good Luck!!
