Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 2004 Jeep Wrangler. Leaking coolant is one of the more common types of fluid leaks on Wranglers. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your Wrangler's engine and keeps it from overheating. Coolant can leak from the reservoir or from the hoses, in 2004 Wranglers with the 4.0 liter engine, coolant leaks are most likely to occur where the hoses connect to the engine. The video above shows you where the coolant reservoir, hoses and connections on your 2004 Wrangler Rubicon are located and the steps needed to fix minor leaks.

A few things to note about coolant is that it is sweet tasting and highly toxic, so it can end up in the dog's stomach pretty quickly. If you ignore a small coolant leak long enough, you will run out of coolant, which leads to an overheated engine and other serious, but highly avoidable, problems. In many 2004 Wranglers, an anti-freeze leak can cause the temp sensor to record high engine temperatures. Always protect yourself with safety glasses and gloves when working with the coolant on your Wrangler.

Why is coolant leaking from the front of my engine?

Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak. The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak.

Can coolant leak from the engine block?

A cracked engine block can cause a range of problems. Ultimately, since the circulation system that cools the engine is comparatively fragile, a cracked engine block will lead to coolant leaking out of the area it is needed and leaving the engine to overheat.

Where is most common place for coolant leak?

One common place of a coolant leak is the radiator pan gasket. The drain plug can also cause leaking, and if the cap that seals the radiator can no longer contain the pressurized coolant, it will leak or spray out from underneath.

What happens if a coolant is leaking from the bottom of the engine?

Without the proper coolant level, even a short drive could cause your engine to overheat and stop working. This chain reaction is much more difficult to fix than repairing a simple leak. If you have a very small, slow leak, ensure your coolant is up to the normal level and drive your car to our shop.
