What would cause a radiator hose to expand?
Why hoses become swollen The first is too much pressure. Finally, hoses can become swollen when exposed to very high heats. If your engine has overheated (due to a stuck thermostat, low coolant or for some other reason), it’s possible for superheated coolant to swell the hose.
Can a busted radiator cap cause a car to overheat?
As detailed in our radiator cap article, a busted one cannot hold pressure thus coolant cannot effectively travel around your engine’s cooling system. For that matter, a leaky cap will leak your coolant too. A radiator cap that can’t redirect hot coolant to the overflow reservoir can also cause the radiator hose to collapse.
Can a car overheat with full coolant on?
As such, modern car designs incorporate a cooling system. The most common of course is a liquid-based heat exchanger in the form of a radiator. Sometimes however, there are several things that can go wrong with a car’s radiator. And even sometimes, your car is overheating with full coolant.
Why is my car over heating and building pressure?
Car is overheating and building pressure in top water hos… First problem i noticed was that the car will over heat after 10 minutes of driving but if i accelerated or revved the engine the temp will go down. This worked for about a month, then i popped the radiator, so i changed it out for a new one.

What causes a car to overheat with no coolant?
A radiator cap that can’t redirect hot coolant to the overflow reservoir can also cause the radiator hose to collapse. In particularly bad instances, your hoses might even explode. Having a collapsed or blown out hose of course cuts off the flow of coolant to your hot engine, thus causing overheating.
Can a blown head gasket cause an engine to overheat?
A blown head gasket can push air/compression into the coolant system, and cause air locks which makes your coolant to overheat. It can also cause engine oil to mix with the coolant and cause a restricted flow. A Blown head gasket is often an expensive repair, as you have to remove the head of the engine.
What to do if your car is overheating on a short trip?
Any of the above causes for overheating on short trips. The car is overloaded or being driven too hard. The Fix: Lighten the load and back off the gas. The radiator or block may be clogged. The Fix: Reverse flush the cooling system and fill with fresh coolant.
