Engine Overheating Service

There are several issues that can cause your car engine to overheat. These include car overuse or more severe factors like mechanical or electrical failure. If you come across a situation where the engine’s temperature warning light or check engine light turn on, you need to get your engine checked for any possible damage.

How much does a Engine Overheating Diagnostic cost?

It depends on the type of car you drive and the auto repair shop you go to. Our mechanics are mobile, which means they don't have the overhead that repair shops have. They provide you convenience by coming to your home or office.

How this system works:

In every car, coolant circulates through the engine to absorb and balance heat produced by the engine. The hot liquid is then air cooled to dissipate heat and then the coolant is recirculated in the system. Serious damage to the engine can happen if any of the component in this cooling system stops functioning, that consequently leads to the engine overheating.

Components of the cooling system:

  • Radiator: The coolant is cooled down in a flat, thin radiator tube once it has travelled through the engine. The coolant then gets ready for another round through the engine.
  • Radiator hoses: The hoses shift coolant from one component to another and in the process they can crack given the pressure and heat in the cooling system. This is the point where they need to be replaced
  • Water pump: The function of water pump is to push coolant through the system. Most systems are driven by a belt other than those in a few hybrids and high performance electric vehicles
  • Thermostat: The function of thermostat is to control the coolant flow depending on its temperature. A cold engine holds the coolant until it is is heated to a certain temperature. Following that, the thermostat opens and enables normal flow of coolant to the radiator where it gets cooled.
  • Cooling fan: The cooling fan draws air through the radiator when the vehicle is moving at a slow pace naturally. Fans can either be electric or belt-driven and only operate when required. When the vehicle runs at a normal speed the cooling fans are not in use during ambient temperatures. This is one of the main components that keep the car from engine overheating.
  • Fan switch: its a temperature sensor which regulates the electric fan.

Causes of engine overheating:

System malfunctioning is one of the main reasons of engine overheating. This is often caused by:

  • Low coolant. If due to leaks there are not sufficient coolant running through the system, there will be a heat build up and your engine will overheat. It's always recommended to check for leaks if the coolant is low
  • Faulty cooling fan: The function of a cooling fan is to draw through the radiator when the car moves at a low speed, like in the case of slow moving traffic. A good way to inspect if there is an issue with the fan is to leave the car idle for sometime to heat up, and check under the hood to see if its running. If it's not, you need to immediately call the mechanic to avoid serious engine overheating.
  • Bad thermostat: if you see observe your car overheating regularly at highway speed, it's better to have the thermostat checked by an expert mechanic.
  • Clogged coolant passageways: You need to keep your car’s cooling system and radiator clean to enable them to function properly. Solid deposits are build up in the radiator that keeps the coolant from properly circulating. A smart and inexpensive preventive measure is to have your radiator flushed every year to keep it in shape.

What to expect:

An expert mechanic will come to your office or home to check the cooling system and identify the cause of the engine overheating. You will be provided with a detailed inspection report that includes scope and cost of the required repairs.

How it's done

The mechanic will inspect any fault codes in the onboard computer system. They will inspect the cooling system looking for the source of major internal issues. Once the inspection is done, and the source of engine overheating is identified, they will provide you a detailed inspection report which includes repair scope and cost.

Jack (the Instamek mechanic) called me back when I requested after viewing the inspection report. He provided some really great information and answered the questions that I had. I'd like to thank him for his thorough and in depth inspection as this has helped me understand the condition of the minivan in question. He was also very cordial and easy to speak with. I give him 5 stars. Thank you... Instamek for all your help with my pre-purchase inspection.On another note, I noticed that a few Google reviews are negative. I would advise that it is likely that a lot of those reviews were for older cars that might not be in good condition. What you have to remember is that they are primarily an inspection service. They are trying to demonstrate the current condition of the vehicle. If they were to miss something, that might expose the buyer to unforeseen repair expenses. So, of course they are going to proceed on the side of caution by listing everything they can see and test. And, they cannot look inside the engine either. So, some items might need to further diagnosed by a physical repair shop or monitored for follow-up later. They are not able to do an exhaustive review given their fee of approximately $200, their limited time associated with that fee, and being mobile with limited equipment. I do not think it is reasonable to expect them, or any other auto inspection service, to ascertain the location of an oil leak either. A lot more time would be needed to diagnosis this. It is even difficult for a physical shop to determine the exact location of an oil leak. Sometimes, it is easy to determine while other times it is difficult if there is a lot of oil caked on an engine. Sometimes an engine will have be cleaned and then monitor where a leak occurs over a certain duration. So I think that a lot of the negative comments are not justified nor are they reasonable. I just thought that I would share my opinion and perspective for future users of the inspection service.read more
