More often than not, the radiator will have to be removed and checked for the presence of bubbles when it is submerged in water. The water pump may be tasked with moving the liquid coolant through the network of tubes and passageways in the car coolant system, but it is the radiator cap that maintains the optimal pressure needed to move the coolant-water mixture. Check the air intake piping, fuel filter, fuel pickup in the fuel tank, and fuel shutoff solenoid at the injection pump (1. problems contact webmaster@doityourself.com. If the engine overheats, it can cause cylinder heads to warp and, eventually, crack. Copyright© One of the most common causes of an internal car coolant leak is a leaky head gasket, hopefully not a blown one. The excess fluid flows into the overflow tube and goes into the overflow tank. Checking for external and radiator cap leaks is relatively easy. The reason it goes up and down is because after it gets to a certain temp, your fan kicks on and pulls air through it and cools it back down. Typically when bubbles appear in engine coolant it is because combustion gasses are being forced into the cooling jacket of the engine. Once the leak is identified, you will want to mark it clearly with a marker so that you do not lose track of it in later steps. Failure of the water pump bearing seal or its gasket, or external damage, can cause a coolant leak.
