    Water/coolant leaking from bottom of engine??

    Hi all.
    I have just bought a 1983 N12 EXA and trying to get it fixed for RWC.
    Rego expired 2 years ago. Strangely, it has only done 125,000 KMs...

    There are a few problems that I can see, but I have no experience in fixing a car though.
    The engine starts and runs fine, except the leaks from muffler, the turbo (also?) and issues stated below.

    1. When the engine is running, there's water coming out from the bottom of engine. It is not fuel or oil. Water from radiator?? Can't see where it is coming from.
    2. When I pour the coolant into the radiator, after abt 5 secs of pouring it comes out at the bottom of engine (on the driver side, can't find the source). No leaks at the radiator though.
    3. For the turbo, when it revs up to 3000rpm, turbo kicks in, i can hear the "whistle sound" of the turbo but the engine starts to "cough". Felt like going to stall.
    Is this because of the holes in the muffler? or problem with turbo?
    It runs fine below 3000rpm though.
    4. Also, the radiator fans are not working. And, the locking handle of sunroof is broken. Anywhere to find the parts?


    Engine sounds good, clutch and gearbox works fine too.

    can someone help me with these issues?

    Thinking of sending it to the Mr Muffler. Bad idea?

    Sorry about my poor english.

    Thanks!

    Jack the car up and lie on your back underneath. Check the hoses that go to the oil cooler on the back of the engine block. You'll probably need a torch.

    Remove and clean the plugs that go to the ECU under the passenger seat. It's a common problem.

    Thanks Paul!

    I will do that when I find a jack that is working.

    Btw, my N12 is in Gold too.

    As i stated in the previous thread and as Paul said, chances are its the plugs into the computer under the passenger seat problem, take them out and clean them, wiggle them gently when the problem happens and see if it works, there is a thread on here exactly how to fix them i think use the search function if it is the plugs.

    tried the Stop Leak, but it didn't work.

    tried patching the muffler with muffler bandage... failed too.

    gee... should I spend the money to get it on the road??

    anybody wants to buy it off me??
    i am completely hopeless in fixing cars...

    Thanks, guys!

    I will bring it to a mechanic next week for inspection.
    Hopefully it won't cost me too much.

    Hi all.

    How much would it cost to replace the water pump and get the muffler fixed?

    or is it too much trouble to do it myself?

    thanks!
