After 8 months of procrastination, I've finally investigated the slow coolant loss in my Nf v8 fairlane.
Just recenlty i had the timing cover replaced which corroded right though, i assumed that was going to be the end of my coolant worries.. I was wrong. there is still a small leak which has allways been there since i bought the car, nothing to be worried about really.
I found it comming from the left hand head at the front, (facing the front of the car) not where it joins to the block, but from a round hole about 5cm in diameter, Is this a welch plug? What would of caused this to happen? corrosion maybe? Is this normal for a car thats just ticked over 100,000k's? how much would it be to have it changed?
Much releived after it not being a head gasket. :s5
Have you got a digital multimeter? You can get a cheap one for around $20, I bought mine on-line, forget where though, Dick Smith should have one. You can use it for checking battery condition etc, so it is money well spent.
With the MM, turn to 20 volts, open the coolant top, put the red + in the coolant, don't touch the sides, and the black - on the neg battery terminal. Should read .3V or less (mine is .09). If it is more than .3V, you probably have electrolyis happening . Do this with engine off, and again with engine running with your normal power goodies running, AC, lights, radio.
Electrolysis is caused by some electrical gear grounding through the coolant, ie not earthed properly.
