    Hi there, I'm a bit of a rookie with my commodore; only had it 3 weeks and she's overheating (so says the temp gauge - but no heat will come from the heaters???) anyway a check under the hood and this part is spitting steam/water can anyone tell me what it is? Cheers!

    Its the heater tap/valve it let the hot coolant flow into the heater core in the cab and that where you get the heat from its vacum operated from your dash switch


    When the dial is in the cold part this vavle is closed and when in the hot its open . :thumbsup: :thumbsup: :thumbsup: :thumbsup:

    Looks like you need a new one, not very expensive from memory. The are made of plastic and become very brittle with age.

    It is the Heater tap. Very common component to fail.

    Awsome, thanks a lot for your replys!!!

    Would that also cause the temp gauge to show its overheating when its not?

    Maybe because it's leaking you are low on water and it is getting hotter than usual.

    Did you fill it up with water or coolant after you did the flush?

    Did you bleed the cooling system correctly?

    No, after she heated up during the flush I just let her cool down and i drained the fluid and havent done anything since, I wanted to replace the heat tap before refilling the coolant system.

    As far as bleeding the system correctly, I removed the bottom and top radiator hoses and performed a reverse flush, but not much liquid was coming out of the top hose, I suspect because of the faulty tap. I read round the forums and the only other thing I could have done as far as i know was to remove those two plugs from the block. Is there anything else i could do?

    Thanks for your help.

    When you fill it up with coolant, there is a bleeding nipple where the top radiator hose connects to the engine. With engine running, let it heat up to normal temperature then unscrew the bleeding screw just a little until all the air escapes and coolant starts to flow out.

    Righto- Just picked up new heat tap, and some of those pellets.

    2 x Q's:

    1) Where should I put the pellets?
    2) Where should I fill the coolant up? through the radiator? or that pipe next to it with the yellow capped dip-stick??

    Cheers for the help.

    Regards,

    Mike

    Have you drained and flushed the coolant reservior tank?

    Once coolant reservior tank is emptied

    First fill up that pipe (coolant reservoir tank) with coolant to just above the MAX mark on the yellow capped dipstick.

    Then the pellets and the coolant go in the radiator.

    The reason for not much water coming out may have also been if you had not removed the Thermostat the water could not pass through the engine with much volue.. But thats just from what i read as what you may have missed, also a reverse fluss would be done by the water going in the top and out the bottom as the water flow comes out the top and in the bottom when the engine is running, i hope that this has also helped you out when you do this in the future.
    cheers

    The thermostat housing is located where the top radiator hose connects to the engine.

    You will need to take the engine cover off and undo the two bolts on the thermostat housing to gain access to the thermostat.
