Symptoms of a Broken Jeep Cj7 Radiator
A combustion engine works best when it's at a fairly high operating temperature. However, work it too hot and your car may stall and overheat. That's why the motor of the Jeep CJ7 needs a reliable radiator to keep the temperature at a safe and workable level. The condition of this part worsens as the Jeep is used and abused. The following are some of the many symptoms you should look for to know if your CJ7 has a broken radiator:
Seeing a puddle of coolant and water on your garage floor after parking the Jeep overnight is one sign of a radiator that needs servicing. The liquid you see should only stay inside the components of the cooling system the whole time. If this gets out, it simply means that the radiator, one of the hoses, the pump, or any other part of the system has a leak. Take your time to spot any breaches and see if the problem can be solved by simple repairs or if a complete installation of new ones are necessary.
Depending on the type and brand of coolant your pour in your Jeep's radiator, its color should either be somewhere in between a blue, green, or yellow hue. It should also have a smooth and flowing consistency that's close to pure water. Symptoms of a bad radiator are when the liquid inside it, or on the puddle on the ground (if you have a leak), is brownish and feels sludgy. These indicate that the radiator has lots of internal rust and corrosion, and some of the bad particles have ended up in the fluid. Radiators in this state should immediately be replaced.
Weird temperature readings
A working radiator and cooling system should show you a gauge with a fairly stable temperature reading. A needle that acts in a weird and unpredictable manner is caused by the same rust particles being washed away from the radiator. Rather than staying in the fluid, these relocate to another area inside and hinder the proper flow of coolant. Replacement is the only solution for this type of situation.
