I've noticed coolant dripping from the bash plate onto the garage floor. Looking up from under the car to the right side of the engine (under the alternator as you look up from underneath) I can see a trail of coolant (apparently) coming from a bolt that I think is a water pump bolt-I removed that bolt but the water definitely isn't coming from there. The water seem to be appearing from nowhere-like a spring from a rock! No matter how hard I try I can't pinpoint the exact spot that the leak is coming from-it's not spraying from a hose and it doesn't appear to coming from the water pump housing behind the fan. Any ideas? It's a very slow leak.
Also-has anybody had any water pump or similar work done on a diesel in Adelaide lately that they have been happy with-any recommendations for a competent mechanic?????

Hi Mark - no, the overflow hose is the other side of the engine bay and it's not coming from there. Good idea though - thanks

Funny things Water pumps. They are not always easy to pick if they are faulty. Best bet it to get the coolant system pressure tested. When under pressure the leak will be more apparent. Sometimes you have to also have the motor running while under pressure before the fault is found. A pressure test will find the fault though and some places may not even charge for this, we never used to. Cheers Tony

P/S Also the water pump should have a bleed hole (tell tale) between the fan and the bearing. When the bearing starts to go it usually starts bleeding from this outlet.

Thanks Tony - yes I'd read about a bleed hole in the Gregorys - I think that's what it's ultimately going to prove to be - the water pump seal. It's just so difficult to see that's where it's coming from.

I'll get it pressure tested.

Hi - I've got the Haynes (did i say gregorys?) Mitsubishi Pajero 1983-1996 Pajero Series NA thru NJ.

My Triton is not that year but I have found virtually everyrhing I have needed for my diesel Triton is the same - brakes, gearbox and transfer case lubrication details etc etc. I have never had to strip the actual engine down but I would think it's the same the 2.8 normally aspirated motor is covered in the manual-it's refered to as a 4M40 motor and that's what my Triton is.

I couldn't find one for a my Triton
