Overheating Vehicle With a Suspected Stuck Thermostat

What the customer reported

The vehicle owner reported that the vehicle was overheating and believed the thermostat may be stuck.

What we found and did

The technician began with a no-charge initial assessment of the overheating concern. The radiator was then removed and replaced. The team used the BG machine to withdraw and flush out all fluids from the engine and radiator, then used a BG fluid kit and refreshed the system with new fluid. All of the work was completed in one visit at our Sebring shop.

What Causes Engine Overheating and Smoke?

What the customer reported

The vehicle owner noticed a warning light for high temperature and experienced overheating and some smoke coming from the engine during a short drive.

What we found and did

The technician determined that the coolant system was not functioning properly, which was likely causing the overheating and smoke. The team performed a complete coolant system flush using a BG machine to withdraw and flush out all fluids from the engine and radiator. They then replaced the radiator and engine coolant thermostat to ensure the system was restored to proper working order.

Result

After the repairs, the vehicle's cooling system was functioning correctly, eliminating the overheating and smoke issues.

Pro Tip

If you notice your engine overheating or see smoke, it might be time to check your coolant system. Regular coolant flushes can prevent costly repairs by maintaining your engine's cooling efficiency.

FAQ

Cooling System Repair in Sebring: questions answered

Answered by our licensed technicians serving Sebring.

Can I just add coolant and keep driving?

You can get home that way. But coolant doesn't get used up the way oil does, so if the level dropped, it went somewhere. Topping off without finding the leak means you'll be doing it again, usually at a worse time and in a worse place.

Does running the AC make overheating worse?

It can. The AC condenser sits right in front of the radiator and adds heat exactly where the radiator is trying to shed it, and the compressor puts extra load on the engine. If your car only runs hot with the AC on in traffic, that's a real clue, and the fans are the first thing we test.

Will a coolant flush fix overheating?

Sometimes, if the coolant is old and contaminated and heat transfer has fallen off. More often overheating is a failed part, and a flush just delays finding it. We'd rather test first and tell you which situation you're in.

What kind of coolant does my car take?

It depends on the manufacturer, and the types aren't interchangeable. Mixing them can cause gelling and corrosion inside the system. We look up the specification for your vehicle rather than pouring in whatever says universal on the jug.

How do you know it isn't a head gasket?

There's a test for it. We check the coolant for combustion gases and watch how the system behaves under pressure. That gives a specific answer rather than a guess, and we'd rather rule it out early than have you find it after paying for other parts.
