Hello I have a toyota mr2 86 and the coolant is boiling inside of the overflow container and there is small coolant drip from radiator in front of car. In need of suggestions
I guarantee you, the water is not boiling in the reservoir. There is no heat source there, and even if it came out of the radiator boiling, by the time the coolant traveled down the hose to the tank, it would have lost too much heat to boil.
But if steam is coming out of your radiator into that tank, it would look like it was boiling.
It sounds like you have a radiator leak, and that you are therefore low on coolant, and the engine is overheating. With the car stone cold, open the radiator cap and top off the coolant as full as you possibly can, then replace the cap. While you have the cap in your hand, inspect the rubber gasket that seals it when it is installed. If that gasket is not in good shape, the normal operating pressure will force coolant into the radiator excessively, leaving not enough to cool the engine.
After a short drive that is sufficient to reach operating temperature plus about 5 or 10 minutes, and then allowing the car to fully cool, open the radiator to see if it is still full. It should have developed no substantial amount of space above the coolant surface, it should still be full.
If there is space, perhaps there was some vapor trapped somewhere, so try one more time. But if you are developing space in the radiator, you have a leak.
