Common Cooling System Problems

Most people know that when your car overheats, it typically has to do with a cooling system problem. Whether it is due to poor maintenance or old age, it can result in the same damage. Read on to learn more about what could go wrong with your cooling system and how to avoid these problems:

Low or Contaminated Coolant Fluid

This is the most common cooling system problem. Coolant or antifreeze is what keeps your engine cool and prevents it from overheating. If you don’t have a clean flow of coolant going through your engine, your engine will strain itself. Please follow your automaker’s guidance on coolant flushes.

Malfunctioning Thermostat

The thermostat stays open or close to let coolant flow to your engine. It allows for proper coolant flow depending on the engine temperature. When the thermostat malfunctions or gets stuck, you risk overheating your engine.

Faulty Radiator

If the radiator is clogged, the coolant won't be able to flow through it properly. Debris can build up inside it. If left long enough, it can cause rust and holes in your radiator. If your radiator is damaged, please bring it to Auto DR for repairs.

Bad Hoses

Hoses guide the path of the fluid. If they are old, cracked, or leaking, your engine won’t get enough coolant. It's important to have a professional mechanic check your hoses regularly for signs of wear and tear. Luckily, it can be fixed with replacements.
