What causes radiator hoses to split?
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. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum.
Where does the radiator hose attach to the thermostat?
The upper hose attaches from the top of the radiator to the top of the engine at the thermostat housing. The lower hose attaches from the bottom of the radiator to the water pump of the engine. If you suspect either radiator hose is failing, watch for the following symptoms: 1. Leaking coolant
What are the different types of radiator hoses?
There are 3 different types of radiator hose connections, gear clamps, banded clamps and wire clamps. Gear clamps, which are sometimes called worm clamps, and banded clamps, which are also called screw clamps, are typically made of stainless steel and wrap around the hose. You adjust these types of clamps with a screwdriver.
What happens when a radiator hose is not replaced?
Radiator hoses circulate coolant from the radiator to parts of the engine that need to stay cool. Over time, radiator hoses can weaken. If they are not replaced when necessary, they can completely collapse, causing the engine to overheat and unable to run. In extreme cases, a collapsed hose can cause the engine to burst.
How to get the top radiator hose to be hot?
1 Remove the splash tray and push the coolant catch tray in. 2 Remove the thermostat cap, usually on the top hose at the engine. 3 Clean the stat seat on the engine and cap. 4 Lube the new stat seal with fresh coolant and fit it, check the orientation (Jiggle valve up). 5 Tighten down the cap bolts and torque to approx 10Nm (89in lbs).
How to know if your radiator hoses are hot or cold?
Start the car from cold, run the engine for 10 minutes or so and check that one hoses is warm and the other cold. That indicates the stat is closed as it should be, so far so good. Now drive the vehicle until normal operating temperature is reached. Shut off the engine and check both hoses, they should now both be warm.
What happens if one of the radiator hoses collapses?
If they are not replaced when necessary, they can completely collapse, causing the engine to overheat and unable to run. In extreme cases, a collapsed hose can cause the engine to burst. This article covers how to check radiator hoses, which may help you keep your engine from overheating. Find both of your radiator hoses.

What does the thermostat on a radiator do?
The thermostat has a special function within the circuit, it’s job is to restrict coolant flow back to the radiator when coolant temperature is below 180 deg F (83 deg C). Above this temperature a wax filled cylinder within the stat melts and expands causing the valve to open proportionally until fully open at about 199 deg F (93 deg C).
