What causes a radiator hose Cap to collapse?
Engine overheating is not necessarily a cause or effect of a collapsed hose. The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Caps are rated around 14–16 psi.
Why are there two hoses in a radiator?
Radiator hoses are a vital part of the cooling system that carry hot coolant from the engine through the radiator and circulate it back — cooler — to the engine again. There are two hoses, the upper and lower, and they’re thick and sturdy enough to handle both high pressures and immense heat.
What makes a radiator hose collapse?
The main cause of a radiator hose collapse is that the hose is not strong enough to be connected to the radiator, but you may also find that the coolant system has developed a partial vacuum, causing the hose to collapse. Coolant decreases as the car cools after use, sucking the hose into the radiator system.
Can a bad radiator hose cause overheating?
The radiator hose may be to blame because they crack and leak over the years from the high heat and pressure they are exposed to. The radiator hose is the most common cause for overheating. If the engine is allowed to continue to overheat, it may cause the engine to fail and the vehicle will no longer operate.
Why is my top radiator hose collapse?
If the vacuum valve in the radiator cap fails, the resulting vacuum in the cooling system can cause a radiator hose to collapse. A malfunctioning radiator cap can also constrict coolant flow.
