Help! My car is overheating and I don’t know what to do about it. I have to add coolant to the plastic overflow bottle regularly and the temp gauges starts to climb up so I know I have to add more coolant.
Yep, I hear this all day long. First thing I do in my shop when I get an overheating car complaint is start with a cooling system pressure test to rule out a possible coolant leak (which is usually what is happening), you could have an internal coolant leak inside the engine from a “blown head gasket” or this could be from a simple external leak like from a leaking radiator hose or water pump.
I found this video where the guy is using a cooling system pressure tester. You can rent one at your local auto parts supplier or you can pay a local mechanic to do it for you. If you are constantly adding coolant, do this step first.
If you are NOT constantly adding coolant to the system you might have a restriction in the radiator, a “stuck” thermostat or a faulty radiator cooling fan motor…which will usually cause an overheating issue when stuck in traffic at idle for extended periods of time.
Watch my video below where I am talking about the different kinds of overheating situations and what you can do yourself to narrow things down and locate the problem yourself.
