Hello all!! My question is : after a coolant change is it advised or recommended to change the thermostat too? Or the reservoir cap or the radiator drain plug? I ve got a late 2011 Chevy Aveo T300 ( named Sonic în The US) and I don t know if I should also replace the thermostat or reservoir cap. The dealer charges too much for a coolant change and I was thinking about changing it myself or at a regular car service but I want it done good since I haven t changed it since I bought the car and it s a very important thing. Will use DexCool anti freeze diluted 50 50.
Thank you very much în advance!
