Noticed the car is warming up and going to a higher temp than ever before. Car is pushing 90,000 miles on an 05. About to replace the thermostat, had antifreeze done few months back.. Anything else im missing, tips please..
There is a leak in the cooling system, not allowing the system to properly pressurize.
There is air in the system, possibly from the coolant change.
The radiator cap is faulty, not letting the system pressurize properly.
The thermostat is stuck closed.
Your low on coolant.
You have a head gasket leak or lower intake manifold gasket leak.
I would start with looking for a possible leak... so inspect coolant elbows, lower and upper radiator hoses, and the radiator itself. If there are no leaks, move on to changing the thermostat and properly bleed the air from the system.
Also, is there any milkshake looking gunk in your overflow tank or when you open the radiator cap.
I have done headgaskets 2 3400's that blew all the coolant in the reservoir an didn't have a drop of coolant in the oil, and overheated in a mile of my house. I don't think anything is wrong, a new thermostat will make the car heat up quicker.
