Your Jeep’s radiator works continually to control your engine temperature. Your engine needs to be hot enough to work efficiently but not hot enough to cause damage. In time, your radiator can become damaged, and you’ll need to visit your Jeep dealer for a radiator repair. These are a few of the signs that your radiator has a problem.
Signs You Need a Radiator Repair at Your Jeep Dealer
Damaged Radiator Cap
The radiator cap’s most important function is to maintain high pressure in the cooling system. High pressure in the system is essential as the coolant must be able to move quickly to absorb and remove heat. Heat generates pressure, and if the pressure inside the system rises too high, the radiator cap temporarily opens to bleed off the excess pressure.
The cap is tightly screwed into the top of your radiator, and it has two seals that ensure that it has an airtight fit. Air in the cooling system will reduce the pressure and will create air bubbles that can block the hoses and tubes. Constant heat and pressure can damage the seals over time, and coolant can leak out. We’ll examine the radiator cap and replace any damaged seals to fix this problem.
Old Coolant
Coolant is a vital part of your cooling system, as it absorbs engine heat and transports it to the radiator where it’s dissipated by heat exchange. Like the other fluids in your Jeep, coolant needs to be changed regularly according to the service schedule in your car manual. On average, coolant should be changed every 30,000 miles or two years.
Older coolant becomes acidic and can damage the radiator, water pump, hoses, and other vital parts of the cooling system. In addition, it is thicker and slower, which reduces its ability to swiftly remove engine heat. If your coolant turns acidic, we can drain the system, flush it to remove any remaining debris, and refill it with fresh coolant.
Blocked Fins
The thin horizontal tubes on the face of your radiator are also known as fins. They provide a large surface area to speed up the heat removal process. When you’re driving, air enters the radiator via the grille and blows across the tubes to dissipate the heat in the coolant. Unfortunately, air isn’t the only thing that blows in. Leaves, twigs, dirt, and other debris will enter through the grille and can clog the fins.
If your fins are clogged with debris, cooling becomes much less efficient, and this can cause your engine temperature to rise. If the engine gets hot enough, it can overheat and suffer extensive damage. We can fix this problem by clearing the debris, and your cooling system will work efficiently again.
