If your engine overheats, you'll see a warning light show up on the dashboard, and the temperature gauge will move into the red. If left for too long, the coolant in your engine will boil over, and steam will rush out from underneath your hood. Obviously, this is indicative of a problem with your engine's coolant system, and can cause various other problems that could be costly to fix if left unchecked. Thankfully, there are a few simple things that you can do that might be able to fix an engine heating issue.

Blocked Radiator

If your radiator has become clogged with debris, which can happen over time due to general wear and tear, it may be slowing the flow of coolant throughout your engine. This can cause the temperature to rise in the engine at a faster rate than normal, which can translate into overheating. In order to fix this, you should have a mechanic take your radiator out and see if it needs to be cleaned out (a fairly inexpensive process) or completely replaced (significantly more costly).

Low Oil

If your engine does not have enough oil, it will collect more heat. This is because in addition to lubricating the moving parts of the engine, oil is used to remove excess heat in tandem with the coolant system. Check your oil dipstick to see if you need to add more oil to the reservoir.

Damaged Pressure Cap

Check the pressure cap located on top of the radiator under the hood. It is possible that over time, the pressure cap has become damaged, allowing pressure to escape out of the coolant system. If this is the case, the coolant cannot circulate properly, leading to overheating. If the pressure cap is visibly damaged, don't try to replace it yourself, as it can be dangerous. Instead, take your vehicle into a mechanic to have the cap replaced.

Damaged Hoses

The hoses attached to the radiator are made out of soft rubber, and can become damaged over time. If there is a hole, coolant will leak out of the system, preventing the engine from cooling while operating. Additionally, check to see if the hose has collapsed in on itself, which can happen if the pump malfunctions. If there is a hole, the hose will have to be replaced, but if it has simply collapsed in on itself, a mechanic should be able to fix it simply by disconnecting it.
