Jeep Wrangler TJ Radiator
Safekeeping Tips for a Longer Jeep Wrangler (TJ) Radiator Lifespan
Keeping your radiator in good condition prevents engine failure. This is primarily because your car's cooling system gets air through the radiator when the vehicle is running. With continued use, your Jeep Wrangler (TJ) radiator can get damaged and eventually fail. To extend the lifespan of your vehicle's radiator, perform necessary care and maintenance routines such as below:
- Wash the radiator fins once a year.
Make it a habit to clean the radiator's exterior every 12 months. You can do this in an hour or less, depending on how familiar you are with the radiator and its nearby components. Just be sure you have the tools prepared, including a hose with nozzle and a soft-bristle nylon brush.
Once your car has cooled down, use the nylon brush to cautiously brush the radiator fins. Brush them in the direction of the radiator fins, as brushing them in the wrong direction can cause it to get deformed. Also, be gentle when brushing the fins, as these can break if you brush too hard. After brushing the fins, rinse off the radiator body using moderate streams of water. Avoid using pressurized or very strong streams of water, as the radiator fins can get bent.
- Monitor the radiator fluid level.
Check your vehicle's radiator level regularly by opening the hood and looking for the radiator fluid overflow receptacle. This side tank is usually attached to the edge of the engine compartment. Examine the indicators to determine your radiator fluid level. When the fluid level is already low or empty, refill the tank with new fluid; make sure you keep a 50/50 mixture of radiator fluid and mineral-free water.
If you notice that the radiator fluid level is always low, then you probably have a leaking radiator. Check the hoses, as well as the radiator body, and find the leaks. Fix the leaking components as soon as you spot them to prevent further damage to the radiator system.
- Perform a radiator flush once a in a while.
Keep radiator problems away by flushing the radiator every now and then. Be careful when opening the radiator, because the fluid can erupt and leave you with burns. Never take out the radiator cap when the engine is still hot. Once the radiator is flushed, clean the radiator first before refilling it with new fluid.
