Car is overheating Inspection

HomeServicesDiagnosticsCar is overheating Inspection

How this system works:

Every car has a system that circulates coolant, a mixture of anti­freeze and water, through the engine to absorb heat created by the combustion process and the friction created by moving parts within the engine. The hot liquid is then air-cooled to dissipate the heat, and the process repeats, over and over again. If any component in that system stops working and you ignore the problem, your car’s engine will melt into a solid block of useless metal in no time flat. A basic cooling system is made up of the following components:

Common reasons for this to happen:

An engine will overheat any time the cooling system is malfunctioning (i.e., when the coolant doesn’t absorb, transport, and dissipate heat effectively). Diagnosing the reason why your cooling system is on the fritz is more complex, but there are several common culprits of an overheating engine:

Low coolant
Although said above, it is worth reiterating: Your engine relies on coolant to dissipate heat. If you don’t have enough coolant running through the system ­­due to leaks, ruptured hoses, loose hose clamps, whatever heat will build up, and your engine will overheat. So check the coolant level regularly, make sure the ratio of water to antifreeze is correct per your owner’s manual, and have it changed every year. If the coolant is low, do not just top it off and forget about it. The cooling system is sealed and the coolant had to go somewhere. It may have leaked outside the engine and you just can’t see it yet or it has leaked inside the engine where you normally would not see it, but it had to go somewhere.
Bad cooling fan
A cooling fan draws air through your radiator when your car isn’t going fast enough to ram it through on its own, such as in slow-moving traffic. A simple way to diagnose whether there is a problem with the fan is to let your car idle long enough to heat up. Then, look under the hood to see if it is running. If it’s not, call a mechanic immediately.
Faulty thermostat
If your car regularly overheats at highway speeds, have the thermostat checked by a mechanic. But at highway speeds, your engine is doing a lot of work and needs a lot of help to keep from losing its cool. If the thermostat doesn’t open, not enough coolant will flow through the engine to keep it cool.
Plugged coolant passageways
Your car’s radiator and cooling system need to be clean to be cool. Over time, the radiator builds solid deposits that can clog it and prevent the coolant from circulating properly. A quick, inexpensive radiator flush every year can keep the system in shape.

What to expect:

A top-rated mobile mechanic will come to your home or office to inspect the entire cooling system and determine the source and cause of the overheating issue. The mechanic will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

How it’s done:

The mechanic will check for any fault codes in the car’s onboard computer system. They will check the entire cooling system, looking closely for leaks and any mechanical damage. The mechanic will also check for any indication of major internal issues.

How important is this service?

Lack of cooling system maintenance is the number one cause of engine failure worldwide — not only in automobiles, but also in motorcycles, boats, and generators. In the ‘70s, there were issues with bearing failures. In the ‘80s, there were problems with pistons. In the ‘90s, the main problems were focused on oil consumption. Thanks to advancements is metallurgy, engineering, and manufacturing techniques, those failures are all a thing of the past. Keep clean oil in your engine and keep the engine cool, and it will enjoy a very long life of service.
