Installed right behind the car or truck's grille, Radiators are an important part of the cooling system. The Radiator is vital to the cooling system as it contains the coolant resources that are crucial to pass through the engine.

Research on Radiator for Chevrolet Trailblazer

Keep your Trailblazer's engine cool by keeping your radiator in good working order. The radiator is critical to your engine's cooling system, but it is made from delicate materials that can break. When this happens, your radiator develops a leak that can only be fixed by replacing the unit. You'll notice several signs to let you know when you need a Trailblazer radiator replacement. Don't ignore these signs because if your engine overheats, you could experience catastrophic damage.

What Does the Radiator Do in a Car?

The radiator sits at the front of your Trailblazer and it contains several tubes through which the coolant passes. As you drive, your engine heats up from normal use, and when it reaches a certain temperature, the thermostat triggers the coolant to begin flowing. When the coolant reaches the radiator, it's hot from engine heat it's absorbed by passing through hoses around the engine block. At the radiator, the heat is released to the atmosphere. The now cooler coolant returns to the engine to draw off more heat. As this process repeats, your engine stays at a safe operating temperature. The cooling system is closed, which means that there should not be any openings to allow coolant to leak out. When a leak happens, you won't have as much coolant, risking the engine to overheat.

Signs of a Bad Radiator

A leak in your radiator is obviously the reason for failure. You might notice bright green coolant on the ground under your Trailblazer when you park your vehicle. Sometimes, a leak is not readily visible. It's a good practice to regularly check your coolant level, and if it drops, you should suspect a leak somewhere in your cooling system. Check the hoses and connections, too, because a leaky radiator could be secondary to leaky hoses. Periodically look at your temperature gauge when driving. If it rises higher than normal, you may need a new radiator or even a 2004 Chevy Trailblazer radiator fan. The fan pulls outside air over the radiator, and a damaged fan can make the engine overheat just as a leaky radiator can.

Causes of Radiator Leaks

The most obvious cause of a radiator is a front-end collision. You may also lose the Trailblazer radiator drain plug when flushing the radiator, but you can purchase a new drain plug to fix that problem instead of replacing your whole radiator. Flushing your radiator is a good habit to have because debris in coolant can build up on the insides of your radiator and cause leaks later. Excessive heat from an overheated engine may also cause problems. It's best to determine the cause of your radiator leak and fix that before you replace your radiator.

Cost of a New Radiator

The price to replace your radiator depends on what model year of Trailblazer you drive. For example, a 2003 Chevy Trailblazer radiator replacement could run you $727 to $1147 with the new radiator and installation fees. If you install the radiator on your Trailblazer yourself, you'll save the cost of a mechanic's installation, and if you purchase your radiator from PartsGeek.com, you'll spend even less on the part than your mechanic would charge you. Saving money on your new radiator is easy with the help of PartsGeek.com.
