Hi,
Do the radiator hoses feel firm, yet supple when you gently squeeze them?
Does the top radiator hose feel warmer than the bottom hose after the engine has been run?
'''Be careful, ensure that the engine is switched off and the key removed from the ignition when you go to check.'''
If the bottom hose feels 'cooler' it may be that the thermostat is not operating (opening).
To check this:
''Start the engine from cold'' with the radiator cap removed. As the engine warms up, after a while the thermostat will open and you should see the coolant start to move in the neck of the radiator.
''Be careful of the coolant. As it gets hot it expands and may overflow out of the open radiator neck''.
If you do not see any 'flowing' motion, the engine coolant thermostat may not be opening, allowing the coolant to circulate through the engine to cool it. If the movement seems sluggish then you may have a blockage in the radiator core, restricting the flow.
-Also, when you engine is hot can you see (or hear) whether the radiator cooling fan is operating?
+Also, when your engine is hot can you see (or hear) whether the radiator cooling fan is operating?
