Why is my 2004 Honda CR-V overheating?
While there are a variety of reasons your Honda CR-V is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Should my radiator cap be hot?
Doesn’t matter what the ambient air temp is, the radiator cap should be too hot to touch after a drive.
Can a defective radiator cap cause engine to overheat?
A defective radiator cap will cause engine overheating in a number of ways. Three of the ways a radiator cap can cause overheating are, 1) Not holding in pressure and allowing the coolant to vent out or escape the cooling system. 2) No providing the proper pressure and not raising the boiling point.
What causes a Honda CRV engine to overheat?
While there are a variety of reasons your Honda CR-V is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. When the radiator fans stop functioning properly, the engine temperature will rise.
How can you tell if your Radiator Cap is stuck?
Below are the top 5 signs. If the radiator cap is stuck, fluid cannot get released. This will cause pressure to build inside of the radiator, causing the hose to leak or break open. If you notice coolant fluid near the radiator or the radiator cap, then you clearly have leaky coolant.
Where does the radiator cap go on a car?
The radiator cap sits on top of the radiator and contains a spring-loaded plunger. When the car is cold, the cap can be removed to check the coolant level inside the radiator, or to add coolant. When working properly, the cap provides a tight seal that helps keep your car’s cooling system pressurized.
What to do if your Radiator Cap is loose?
Open the hood, check that your radiator is fully filled by opening the cap. Then tighten the cap and run the engine until it reaches operating temperature. If you see liquid around your radiator cap, then it is loose or broken and must be fixed.

Can a bad radiator cap cause the overflow tank to collapse?
While you’re in there, check to make sure your coolant overflow tank is working properly. You may have a bad radiator cap if the radiator hose collapses. The vacuum won’t be released by the radiator cap properly and it will cause the radiator hose to collapse during the cooling down period.
What does the pressure cap on a radiator do?
The part of a vehicle known as the “radiator pressure cap” contains 2 valves. Its purpose is to contain coolant in the radiator and ensure that the cooling system remains pressurized.
