Jeep Cj5 Radiator Overflow Tank Troubleshooting
Everybody needs some backup every once and a while, and that's exactly what the overflow tank is to your radiator. When the coolant in your radiator gets too hot, it overflows. To ensure that this vital coolant doesn't go to waste, it is stored in the radiator overflow tank. And when the engine cools back down, the coolant is sucked back into the radiator. If your Jeep Cj5 radiator overflow tank becomes damaged, then it could lead to unwanted radiator and engine issues. To help you diagnose and solve such problems, here are some overflow tank troubleshooting tips.
A radiator overflow tank leak can become your greatest enemy as this would deplete your vehicle of coolant, which could lead to engine and overheating problems. Leaks are often caused by cracks in the tank that are brought about by wear and tear. Check your overflow tank to see if it has crack or if it is leaking. If either situation seems to be the case, then seal up the cracks to stop the leaks.
When you inspect your radiator overflow tank, keep an eye out for rust. If you don't spot the rust, then check your actual coolant. If there is a reddish, clay substance inside your coolant-or if the coolant itself shows a brownish color-then you likely have a rusted overflow tank. There are methods of removing rust in order to get your tank back to prime form and keep the coolant clean. However, if the rust has caused serious corrosion, then you're better off having the entire tank replaced/.
Loose brackets and bolts
A radiator overflow tank is typically held in place by brackets that bolt it to the vehicle. If ever these bolts come loose or your brackets break, then your tank may not be able to store the coolant properly. In addition to that, a tank that isn't properly supported could lead to tank leakage as well. When you check the condition of your tank, be sure to inspect its bolts and brackets. If these have come loose or are damaged, then have them replaced.
