Today my car started overheating. My friend said my oil was very low and coolent. He filled both and I drove the 4 miles home. By the time I was pulling in it started to overheat again. Did it not have time to go through the engine/radiator in 4 miles and would possibly be ok once I drive it further? I'm a single mom on a limited income and clueless about my car. It's been a year since I've had an oil change and even touched my fluids so could this be the reason? It states no appointments available in my 87112 zipcode.
My car has 120000 miles.
My car has an automatic transmission.
Hi There, Your car may be overheating for a variety of reasons such as low coolant and/or low oil. Other things that can cause overheating are things like a faulty thermostat, a clogged radiator or a failing coolant fan switch. The coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. You may also have a water pump that is beginning to fail. Water pumps often times will begin to produce a bit of a whining sound when they are starting to fail. A common problem also associated with this is the water pump may begin to leak around the water pump shaft due to the seal being damaged. In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator. Lastly, you may have a failing cylinder head gasket allowing coolant to leak from the water passages into the cylinders resulting in the coolant being burnt in the combustion chamber with the fuel. If this is the case, you may also notice a bit of white smoke coming from your exhaust which is a product of the coolant being turned into a steam like vapor. I would suggest having an expert from Your Mechanic come to your home to diagnose your cooling system.
