How to Check
For the practical test, the Tell Me/Show me question :-
Please open the bonnet, identify where you would check the engine coolant level and tell me how you would check that the engine has the correct level.
What you have to do :-
Identify high/low level markings on header tank where fitted or radiator filler cap, and describe how to top up to correct level.
Caution! Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator. Wait until the engine and radiator cool down.
Check the coolant level in the reservoir tank when the engine is cold. If the coolant level is below the "MIN", add coolant up to the "MAX" level.
If the reservoir tank is empty, check the coolant level in the radiator When the engine is cold. If coolant level is not at the top of the radiator, fill with undiluted coolant up to the filler opening and also add it to the reservoir tank up to the "MAX" level.
NOTE: Some older vehicles do not have a coolant reservoir tank. If this is the case for your vehicle, then just remove the radiator cap and check the coolant is up to the filler opening.
That's it. The coolant level has been checked.
