Probably a blown head gasket
There is no radiator cap, you must fill through the coolant reservoir.
The cooling system on this vehicle does not use a radiator cap on the radiator but on a remote tank. It may have a different (larger) cap on it than what you are used to seeing on the radiator.
The coolant filler cap can be located in two places....depending the model of vehicle. On late model cars, it's located usually on the left or right side of vehicle in the engine compartment. Usually its a clear plastic tank with hot or cold markings on it. And the top of tank has a cap on it usually with the word coolant on it. On older cars, its located on top of the radiator which is in front of the engine. Normally located on the left side of radiator. It will usually be made out of a hard plastic or metal with the words caution..underpressure...or coolant, etc.
Could be thermostat is not opening or collar on radiator is defective and needs to e resoldered sounds like a blown head gasket.
Drain existing coolant from the plug at the bottom or rear of the radiator Flush radiator with clean water until water runs clear Re-fill radiator slowly (to prevent an airlock) with a mixture of 50/50 water and antifreeze Run engine to normal operating temperature with heater on Re-check coolant level
There is not a radiator cap, there is a coolant reservoir and it has a plastic cap that controls the pressure in the coolant circuit.
A lot of vehicles don't have the radiator cap on the radiator , they use a thread on style cap on the engine coolant reservoir ( that is the pressure cap / radiator cap )
No , the " radiator " cap / pressure cap is the thread on cap on the engine coolant reservoir
there is no real radiator cap. On the left side of engine compartment there is a coolant jug. This where you would add coolant to radiator.
If you have a threaded cap on your coolant reservoir that is your " radiator cap "
The thread on cap on your engine coolant reservoir is your pressure cap / radiator cap
The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
The thread on cap on your engine coolant reservoir is your pressure cap / radiator cap
Run engine to normal operating temperature witout radiator cap Observe coolant circulation If coolant blows out of radiator - could be a stuck thermostat If no circulation could be a bad water pump
It's only radiator cap is on the coolant reservoir.
The "radiator" cap is located on the coolant reservoir.
It uses the cap on the coolant recovery tank as its "radiator cap".
