One of the most important parts of a car is the radiator. Some even say it’s the most important part of the car.Whether or notthat is true, the radiator is needed for the proper function of the engine. Without the radiator, the engine will overheat and you won’t be able to drive your truck. Maintenance on GMC truck radiators should be done at least twice a year to keep in top shape, but there could also be some signs that you need to replace your radiator.
Leaking Coolant: Coolant is an important part of the system and one of the things that keeps the engine functioning at the right temperature. If you see leaking coolant that is spilling to the ground underneath the truck, then there could be a problem with the radiator. This can happen while you are driving or when you are parked. A colored dye test will be done to check out the radiator's cooling system. If the dye leaks out, then the radiator could be cracked and will need to be replaced.
Overheating Vehicle: If your truck is constantly overheating, even when you aren’t driving that far, this could indicate an issue with your radiator. Once your truck overheats the second time, you need to address the issue. If the issue is left for some time, then it can cause more damage to the radiator.
Discolored Coolant: Radiator coolant is typically yellow, green, or red. If the radiator is older, the coolant can turn to a rusty color and then become a thick sludge. The sludge is bad for your radiator and eventually will clog the system. If the sludge accumulates in the radiator, you will need a new one.
Low Levels of Coolant: If the coolant levels are low and the coolant light is on a lot, then it’s time for a check up. If you ignore this problem, it could be too late and you will eventually need to replace the radiator.
Rust Accumulation: When doing maintenance on your truck, check the coolant for any signs of rust. If it’s a brown color, this could mean you have rust accumulation in the cooling system and the radiator will need to be flushed. Use distilled water and coolant that is high quality when refilling your radiator to avoid failure and having to replace it.
A Bad Thermostat: If the truck is always overheating, then it could be because of a faulty thermostat in the radiator system. It’s one of the most common causes of radiators overheating. The thermostat should be replaced before you have to purchase a new radiator.
A Car Accident: If you have been in a head on collision, then your radiator is more susceptible to damage and may need to be replaced. Repair can be complicated, so sometimes it’s cheaper to look at new GMC truck radiators.
