Romove the upper water heater (coolant) hose. Pull two bolts out. Becarefull not to lose the nuts they tend to fall. You can use high heat sealant to replace gasket (gold tube). Let sealant sit for 10 minutes or until it gets a skin on it, and reassemble. Don't for get to buy coolant to replace what is lost. -----------------------------------------------------------------------------------------------------------------

Replace thermostat. DO NOT remove the upper radiator hose. Follow the bottom radiator hose ( if you are standing in front of the car facing the windshield it's on the bottom left of radiator ), there are two bolts you need to remove. The thermostat sits in there. It should take about 10 minutes total to remove the old and replace with a new one. I followed the above information and ended up removing way too many pieces to name to get the housing at the end of that hose open.
