Engine Ran Hot and Needed Coolant: Where Was It Leaking?

Engine Ran Hot and Needed Coolant: Where Was It Leaking?

What the customer reported

The vehicle owner reported the engine ran hot, added coolant, and said it seemed to be ok, but asked the shop to check for a coolant leak.

What we found and did

At our Haines City shop, the technician found the water pump and the radiator were both leaking, causing coolant loss and the over temp concern. The technician removed and replaced both parts, taking off other components as required to reach and install them. Additional fluids were used to complete the service, and the repair order called for a retest and a final road test to verify the repair.

Coolant Light and Oil Light On, Had to Add Coolant

Coolant Light and Oil Light On, Had to Add Coolant

What the customer reported

The vehicle owner reported that the oil light and coolant light both came on and that coolant had to be added to top off the system. They asked for a re-check of the issue.

What we found and did

The technician found a thermostat stuck open, which was the main concern behind the check engine light. The team ran initial testing and ECM/PCM diagnostic testing, then replaced the thermostat housing at our Haines City shop. An oil change with Mobil 1 was also done because service was due and the oil level was low, with no leaks found.

Temp Gauge Stuck on Cold and Fans Running After Shutoff

What the customer reported

The vehicle owner reported that the temperature gauge was all the way at cold and the fans seemed to continue to run after the vehicle was shut off. The check engine light came on the day before, the issue had been occurring for 6 months, and the A/C blew warm when it happened. The owner had been disconnecting the battery to reset the system, which seemed to fix it for a bit, and the temp gauge had never been hot.

What we found and did

The technician replaced the thermostat housing along with the coolant temperature sensor, with the check engine light as the starting point for the concern. Components were removed and replaced as required to access and install the parts, and additional fluids were added as needed to complete the service. The repair was then retested and verified as part of the job at our Haines City shop.

What the customer reported

The vehicle owner reported a coolant leak at the connector to the transmission.

The same visit at our Haines City shop also included an engine coolant thermostat housing replacement, recommended for coolant system compromise, and a water pump replacement for an intermittent noise that came and went with no leak at the time.

Car Overheating With Cooling Fans Not Turning On

What the customer reported

The vehicle was overheating, and the cooling fans were not turning on. The radiator was also leaking and the thermostat was sticking.

What we found and did

The technician found the wiring compromised on both cooling fans, even though both had power and ground. The team replaced both cooling fan assemblies, replaced the thermostat with a gasket because it was sticking, and replaced the leaking radiator assembly. A full synthetic oil change to vehicle specs was also done because of the overtemp, and the repair was retested and verified.

Overheating Light Flashed on the Highway, Then Kept Returning

Overheating Light Flashed on the Highway, Then Kept Returning

What the customer reported

The customer was driving on the highway when the overheating notification light came on for approximately 30 seconds. After pulling over to let the vehicle cool down, the temperature never reached the red limit, but the vehicle continued to overheat when driven, with no liquids leaking and no smoke.

What we found and did

The technician removed and replaced the engine coolant thermostat housing. The team used a BG machine to withdraw and flush out all fluids from the engine and radiator, then refreshed the system with new fluid from a BG fluid kit. The brake fluid was also found dark and taking on moisture, so the team flushed the brake system reservoir and lines, replaced the fluid, and cleaned the reservoir area at our Haines City shop.

FAQ

Cooling System Repair in Haines City: questions answered

Answered by our technicians serving Haines City.

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.
