What makes radiator hoses burst?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Another common problem is clogging of the smaller radiator runoff hose, which leads to the coolant tank. The coolant must be drained to replace the hoses.
What causes too much pressure in radiator hose?
The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure. That pressure buildup will eventually spell doom for your radiator hoses. If your radiator is too corroded, this can cause a leak in the body of your radiator even if the hoses are intact.
What causes a radiator hose to blow on a bad fan?
Bad thermostat would cause lower pressure in that hose not higher. Before that hose should blow the radiator cap should release pressure. Even on plugged radiator the cap to release pressure. With a bad fan clutch or water pump the hose shouldn’t blow. The radiator cap is the safety for the cooling system.
What causes the pressure on the lower radiator hose?
The lower hose is the suction to the water pump and really no way for it over pressurize. If anything you want to check would be the radiator cap. That can cause the pressure to go up in the whole system if your low on coolant and you start to over heat. Thanks for the replies.
Can a bad radiator hose cause engine damage?
In other cases a cooling system fault can cause the hose to collapse. In either case an inspection must be performed as a coolant hose that has collapsed cannot flow coolant properly. This can result in the vehicle overheating and engine damage. 5. Radiator hose is broken
What does it mean when your radiator hose pops off?
The hose fits on it snugly and clamps down tight. I would pressure test the system to see when this hose pops off. If it pops off at a pressure below what the cap is rated, then it’s not clamping tight enough. If it pops off above what the cap is rated for, then the problem would be the cap.
