Jeep Wrangler YJ Radiator
Maintenance Tips to Follow for Jeep Wrangler (YJ) Radiators
Getting stuck on the side of the road because of an overheated engine in your Jeep Wrangler (YJ) is never a pleasant scene, but this can mostly be prevented by taking good care of your radiator. The Jeep Wrangler (YJ) radiator is the first line of defense against overheating in your truck's engine, but without regular maintenance it will fail eventually.
In this guide, we'll share some basic yet highly effective tips on how to maintain your Jeep Wrangler (YJ) radiator:
- Keep the radiator topped up.
Keeping the radiator filled with coolant at all times arguably remains the best way to keep the radiator running smoothly. While Jeep Wrangler radiators are designed to be self-contained, coolant will still gradually leak out of the engine. This slow drainage will eventually decrease the radiator's ability to cool the engine, so make sure to keep an eye out for the radiator's coolant level and replenish it when necessary.
- Check for leaks and other signs of damage.
If you notice your truck's radiator loses more coolant than normal, it may indicate leaks on the system. Leaks are a common cause of radiator failure, and may require immediate repair or replacement of the unit depending on the severity of the damage.
Aside from visible signs of cracks, holes, and other types of damage, other indicators of a leak in your radiator also include a noticeable smell of antifreeze in the hood and the sharp rise in the engine thermostat despite running under normal operating conditions. If any of these symptoms appear in your Jeep, have it inspected by a mechanic as soon as possible.
- Avoid using water from the tap.
Filling the radiator with water straight from the nearest faucet will save you money right now, but it comes at a steep cost in the long run. Aside from being ineffective in drawing heat away from the engine compared to engine coolant, tap water also contains calcium impurities which can build up and clog the insides of the radiator.
- Flush the radiator regular.
Flushing the radiator should be a standard practice in your radiator maintenance checklist. Most auto repair shops offer flushing services, although you can also drive up to your local dealership and ask whether they can also flush your Jeep's radiator. Normally, radiators should be flushed at least once every two years or 40,000-50,000 miles.
