How to Diagnose Toyota Camry Radiator Overflow Tank Problems
Overheating is a big no-no for your car. To prevent this from happening, make sure that you have a well-functioning cooling system, including a good-quality radiator overflow tank. The tank, which is sometimes called the expansion tank or the coolant reservoir, does exactly what its name suggests-it catches coolant overflow from the radiator. This way, you can be sure that no coolant reaches the ground and becomes wasted. The function of your radiator overflow tank doesn't end there, as excess coolant stored in the tank is also siphoned back to the radiator once it cools down. To prevent having an overheating engine, we've listed the tell-tale signs of a damaged radiator overflow tank, so you can fix the problem early on.
Excessive bubbles may be art for some but definitely not for your Toyota Camry radiator overflow tank. Bubbles in your coolant suggest problems in your head gasket. To verify, turn off the engine and check the cylinders of your Camry. You can use a cylinder leakage tester to see if bubbles are present in the cylinders. The presence of bubbles means that combustion gas is leaking into your car's cooling system. This needs immediate repair, and it would be best to head to a car service shop right away. Aside from the trouble of overheating, you may have to face blown parts (e.g., head gasket) if you ignore this Toyota Camry radiator overflow tank problem.
Another common and equally nasty Toyota Camry radiator overflow tank problem is leaks. Luckily, this glitch can be repaired even by a home mechanic. To rid your coolant reservoir of leaks, make sure first that it is clean inside out. Pump out the remaining coolant and remove the bolts and other connections. Don't forget to wipe clean the exteriors of your Toyota Camry radiator overflow tank, too. This should help you locate the cracks better. To seal the leaks, apply a two-part epoxy compound on the affected portions.
