[QUOTE="RossKean, post: 1449053, member: 19880"] Cracks in the overflow reservoir are fairly common - especially on earlier Gen II. The plastic gets brittle over time - I had to replace the one on my 2007. When the engine gets hot, coolant flows to the reservoir. As the engine cools, the fluid gets sucked back into the radiator if everything is working right and no lines are kinked or holed. If the fluid leaks out of the tank, air gets sucked back. I suspect your overheat is due to insufficient coolant in the radiator since you have already established that the fans are working. Note: In addition to thermostat, make sure that the radiator cap is tightened fully (and works as it should). Edit: Ignacio was replying while I was typing [/QUOTE]
