    2003 Deville head gasket blown signs

    Gentlemen I own a 2003 deville with 92K on it. I just replaced the water pump due to leaking coolant but now I have a new problem. while facing the engine it is leaking coolant on the left side now. It isnt overheating yet and I dont see any coolant coming out of the reservoir, checked the oil and no coolant in there either. Is this the signs of a head gasket going and what else should I look at to confirm this. Thank you very much

    Re: 2003 Deville head gasket blown signs

    I'm not sure I can give you any definite answers as I'm still learning about all this myself, but in the process of trying to diagnose chronic overheating in my Caddy, I had researched symptoms of failed and failling head gaskets. All I can share with you are the links I bookmarked from when I googled the topic. It's possible you've already seen these, and if so, I apologize. It turns out that replacing the alternator stopped the chronic overheating in my Caddy (it was the repeated failure of the battery that prompted the replacement of the alternator, but it turns out it helped the overheating problem, which I know is not your case).

    Re: 2003 Deville head gasket blown signs

    Northstar's do not leak coolant externally if the head gasket is blown. When you say it's "leaking on left" do you mean the left side of the engine? If so I would suspect either your reservoir tank has a leak or the hose that is routed on the front of the engine. FYI Northstar's do not mix oil and coolant together as well. When you fix your problem make sure you bleed the cooling system correctly otherwise you will have issues with overheating and most of time this is due to a clogged purge line (aka line that goes from surge tank to the right side of the motor. Can't miss it).

    I just hammered on the car to try to get it to overheat and the computer read check coolant while I was driving. Checked the coolant when i got out of car and it was fine. Car did not overheat either.

    When you refilled the system after the water pump replacement, how far up did you fill the surge tank?

    Because the correct full level is to the FULL COLD Line on the tank, about half way up, where the tank halves meet. If it's overfilled, coolant will be expelled through the overflow.

    Maybe I'm assuming it only leaked a small amount? Is the coolant at the correct level?

    how in the world could replacing an alternator -
    have ANY affect - on the "chronic overheating" -
    of your engine?

    -------------------------------------
    what else should I look at to confirm this

    first - check the PURGE LINE FOR PROPER COOLANT FLOW -

    the PURGE LINE is the only way of expelling air from the Northstar cooling system -

    it is a 3/8 diameter hose that goes from a hollow bolt in the thermostat/waterpump housing area of the engine - and plugs onto a nipple on the side of the SERGE TANK -

    with the engine running - there should be a gentle - constant flow of coolant - from the engine - to the serge tank -

    if there is no flow - the most likely cause is a blockage in the hollow bolt -

    follow the hose towards the engine - with the engine OFF - remove the hose - use a straightened metal coat hanger - or something similar - and poke it into the hollow bolt -

    the coat hanger should go in about 2 1/2 inches -

    once the hollow bolt is cleared - you can briefly start the engine to verify coolant flow - be sure to use some sort of container to catch the coolant so you don't make a mess -
    ------------------------------

    NEXT - do a BLOCK TEST -
    it is the DEFINITIVE TEST for failed head gaskets in a Northstsr motor

    At this point, he only has an external leak.

    Re: 2003 Deville head gasket blown signs

    Lets recap.
    1. You have a leak on the right side near the surge tank. (Left and right are always given as viewed from the drivers seat)
    2. Coolant is not overfilled.
    3. You do not see coolant leaking from the overflow tube.
    4. The engine does not overheat.
    Have you checked and confirmed that the surge tank is not cracked? Dried Dex leaves a chalky white telltale residue which may aid in locating your leak.
