What will cause overflow to bubble and car gets hot?
1) Thermostat is bad
2) Radiator is clogged
3) if your losing fluid or hearing a noise, check your water pump.
If your not losing fluid or hearing a noise, the service the radiator by having it flushed. If this doesn't solve your problem, then change the thermostat. If your still having the problem then your radiator may need further service or even replacing.
I'm having the same issue right now. I'm replacing my thermostat next. If it still is running hot, I'm going to take the radiator out and have it serviced.
Good luck! And remember, DONT let the temperature get in the red!!
What makes the liquid in the overflow for the raditor bubble Also it's making antifreeze come out the engine seal not the head gasket what would cause this?
The overflow bottle may overflow if: 1. The car is overheating - this means after the coolant in the radiator gets heated up and expands it flows to the reserve bottle but the radiator doesn't cool down to suck back the coolant from the overflow bottle, but just keeps on sending coolant to the bottle. 2. You may have put excess coolant in the bottle - hence heated coolant from the radiator didn't get enough…
I don't think you can actually overfill a car with antifreeze. There is an overflow chamber that prevents this. Perhaps this overflow can be overfilled but in that case the worst thing that can happen is the little plastic cover pops off and you get some excess antifreeze on the ground. It might also depend on the car. when car gets hot it will push coolant to reservoir (expansion) and when cold, into radiator. this…
This might be the result of an increase in coolant temperature. Once the engine stops the coolant is no longer being circulated and cooled by the radiator but it is still picking up residual heat from the engine. Heated coolant expands and can sometimes overflow. You might also have a bubble of air in the system. Try bleeding it. Or maybe the check valve in the pressure cap is bad.
COULD BE ATF LEAK TRANNY FLUID GETS COOLED BY RADIATOR MAYBE BAD RAD. CAR RUNNING HOT? 91 Seville's use coolant tabs from factory, that can lead people to think they have engine problems. You should have your car a check by a mechanic who can use special tools to check for blown head gaskets or other problems.
