Hello, my name is Bobby. Thank you for the question. Can you tell me how hot it gets and under which driving conditons that it does so. Thank you.
Is it on hot even when started first thing in the morning?
My question was about if it showed hot when the car is first started cold. If it does then you either have a gauge or coolant temperature sensor issue. The sensor is a common failure. Most of the time on this engine though it is a head gasket issue. You can typically borrow a block testing kit at most auti parts stores. It tests for exhaust gases in the coolant to let you know if there is a serious internal engine issue. If that comes back negative then I would suspect either a clog in the radiator or a failure in the cooling fans. As for bleeding the system, you just start and run it and allow it to warm up and then turn it off and allow it to cool. You will do this several times. In some cases you need to jack up the car one at a time on each of the front corners to force the air out as it can get trapped in the engine.
Thank you for getting back with me. If it is getting hot after about 30 minutes then see if the radiator fans are coming on. If they are and it is still hot then you may have a slightly leaking head gasket. You can use a block tester to check this. If the fans are not coming on then you may have a circuit issue that I can tell you how to test with a voltage meter.
