How Long Does It Take To Replace A Radiator?

The radiator maintains the engine temperature with the aid of the coolant fluid. Without the radiator, the engine is nothing but a fireball. If the radiator is broken or does not work properly, the engine will overheat, leading to various issues. If it starts showing problems, you will need to install a new one. How long does it take to replace a radiator?

Depending on your skills with automobile mechanisms and previous experiences, radiator installation time will vary. However, before knowing about the replacement, it will be useful to know about the reasons that are responsible for damaging a radiator.

The Reasons For The Damage Of A Radiator

Several reasons can reduce the efficiency of a radiator and even damage some of its parts. These following things are likely to do the most damage to this important component:

A collision. The radiator is a vulnerable component that can be broken or damaged easily. You may need to repair or even replace it if the car has been on a sideways or head-to-head collision.

Frequent overheating. Overheating is not normal and can lead to serious damage to several components. The radiator is one of them. Although, its main function is to keep the engine heat under control, the system itself is more susceptible to heat-related damage. If the car becomes overheated frequently, you should not neglect this issue. The radiator may become damaged before time.

Damaged pressure cap. The function of this cap is to control the radiator’s pressure. In the case of excessive pressure buildup, the cap decreases it by releasing the antifreeze to overflow the compartment. The regular operation of the radiator depends on the correct pressure management. If the pressure cap is faulty, it cannot control the extra pressure, and the radiator damages itself by overworking.

A broken thermostat. A thermostat helps the pressure cap to control the flow of the coolant. So, the radiator takes a blow if it does not work properly.

How Long Does It Take To Replace A Radiator?

Replacing a radiator is a laborious process, and the time duration varies depending on the skills of the service person. A professional mechanic is unlikely to take more than 2 to 3 hours. It could take another 30 minutes to one hour because the process involves some extra services like removing coolant, broken belts, and a few other things, if necessary.

You may need more times depending on the conditions of some other parts. If the car is old, there is a possibility that electrical connectors and terminals are damaged and the fasteners are broken. You will need to repair and replace these parts for the radiator to resume its operation. Some mechanics may also want to change the antifreeze and replace the radiator hoses.

How long does it take to replace a radiator if the service person is an amateur? In that case, it may take 7 to 8 hours or more. First-timers may have trouble with small parts of the task like locating bolts and other elements. Doing the replacement and installation a couple of times will cut the duration significantly.
