Can coolant leak from reservoir cap?
If the cap isn’t releasing excess pressure properly, that pressure can force the coolant to leak out at the point of least resistance. This can be from the cap, a hose, engine gaskets, the water pump or even from the radiator itself, especially if you have an older vehicle with lots of miles on it.
When to remove the coolant surge pressure cap?
Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If a hiss is heard, wait for that to stop.
Where is the radiator surge tank cap located?
The radiator surge tank cap that vents pressure in the event of excessive cooling system pressure is located on the lower outboard side of the radiator surge tank. The radiator surge tank cap that is located on top of the radiator surge tank is where the cooling system is filled.
What happens when coolant overflows the surge tank?
When that happens, coolant can overflow the surge tank on to the ground, or if there is no tank, coolant is lost. The surge tank usually is marked with minimum and maximum levels.
What does it mean when your Radiator Cap is leaking?
They may tell you the cap is leaking under pressure or intermittently. Coolant goes into the reservoir tank as it expands. The radiator cap releases the extra pressure by sending some coolant into the overflow tank. If you have a bad radiator cap, the coolant could get released too quickly and cause the reservoir to overflow.
