Research on Radiator for Hummer H3

The radiator's primary function is to cool the vehicle's engine. It is the sole system that prevents the engine from overheating and sustaining serious damage. By removing the heat from the engine coolant, the radiator is in continuous operation, and can degrade or fail for many reasons. The results are, of course, very noticeable. Your vehicle will overheat. Radiators are one of those automotive parts that can be easily replaced, but at a cost, but by purchasing parts from the right place, you can save substantially.

How an Automotive Radiator Works

As liquid circulates throughout an internal combustion engine, it becomes very hot. Liquid coolant is pumped through various channels that run through the engine system, and all of it eventually passes through the radiator. As it does, heat is transferred from the fluid in the tubes to the outside air, so the liquid cools. The engine is cooled too. Intake air, air conditioner refrigerant, motor oil, and automatic transmission fluid can be cooled in this way as well. If not, Hummer H3 radiator replacement is required.

Automobile radiators consist of a network of small tubes. A honeycomb of fins help to move the heat away, in a fast and efficient manner. These fins can become bent, which will make the radiator less able to do its job. The fluid is usually circulated by a centrifugal water pump. A thermostat controls the temperature; it is able to control how much liquid flows through the radiator.

Radiator Problems

In addition to bent fins and failed thermostats, radiators can develop coolant leaks. Cracks and corrosion can be the reason. Radiators can also fill with sludge, which can cause damage. Leaking coolant can diminish the amount of fluid in the engine system, causing it to overheat. A Hummer H3 radiator leak is a good reason to visit a mechanic and most likely have it replaced.

How Long Does It Take to Change a Radiator in a Car?

Hummer H3 radiator removal doesn't take a long time. You can have a new radiator and be back on the road in two hours. Installing the part is simple for a professional because it does not have moving parts and fits into a specific location in front of the engine, and behind the grille.

Price for Replacing a Hummer H3 Radiator

The Hummer H3 radiator replacement cost is in a similar range to other automotive parts you might service. For a 2008 model, parts and labor will range from $520 to $716. You'll get luckier if just a radiator fan motor is needed, which is under $200 to replace. For both upper and lower radiator hoses, it is generally under $300. Labor charges will always factor in, since a mechanic must do this work, but you can save on parts. PartsGeek.com offers all the auto parts and accessories you'll need for less, because we sell them exclusively online. There is no overhead of running a brick and mortar operation. You get essential parts that will save you cash and keep your vehicle running like new.
