    Hi!

    We have a 2002 VY v6, it has been overheating. We replaced the heater valve tap as it was cracked thinking that was the issue but it has not stopped the car from overheating.

    Coolant is not bubbling over but there is a bubbling noise from the engine oil and smoke.

    Is there anyone who might be able to help us with what the problem may be?
    Thank you!!

    Did you bleed the cooling system as per the factory requirements?
    Sounds like you're out of your depth. Take it to a mechanic.

    Yes they have bleed the cooling system, I am posting on behalf of my father as he is not internet/forum savvy.

    So I will let him know that you said he is "out of his depth". Thanks for that..!

    Reason i said that you appear to be out of your depth is to do with the description you have given. The boiling temperature on coolant and oil are very different.

    Also, if you continue to operate the vehicle while overheating in your attempts to diagnose the issue you could do irreperable damage to the motor that will cost more than taking it to a mechanic.

    Do you have any secondary leaks?
    What Percentage is the coolant concentration at?
    Is the thermostat operating correctly and at the right temperature?
    Are the fans operating and being triggered correctly?
    Condition of hoses?
    Condition of waterpump?

    Good to hear the issue is sorted but do you mind posting what the actual fault/fix was so that anybody searching my find the answer in the future :)

    To me it actually sounds like it was a faulty radiator cap?

    Smoking? from where?

    Sounds like the tune isn't right if it's stalling on idle.

    Sorry but that is BS, engine should idle fine regardless of the temp as there are specific tables in the tune for the idle. Sound like a crap quality tune to me.

    If you can hear bubbling in the coolant system ,particularly after shutting down the engine it normally suggests the pressure cap is faulty.
