G'day Folkes,
Need some help, has anybody experienced water loss from their 80 diesel.
I have had it pressure tested and to have had no leaks.However they did find a faulty thermostat.We had replaced that and now a few weeks later we seem to
be losing water again.sometimes up to 1-2 litres.It is a concern the cruiser has only done 220000 klms.it is just a pup.Any ideas than the possible cracked head
(hope not knock on wood- compter desk)let me know.
Thanks Again.

Hi
Have a good look around for white residue from coolant.
Places to look are around the rad, thermistat, water pump etc. Sometimes the pump seal leaks when cold, but not when hot. If u can feel or see residue from spray from the fan when cold, it is the pump, and what a joy they are to replace.....did the last one in the Tibaburra Caravan park....the cam cog, belt, and backing plate all has to come out....and go back in the right way!
A hydrocarbon
test is probably your next port of call if u cant find the culpret.
Did the motor overheat badly with the thermistat problem??
Problem is (and ive seen it many times) that once u overheat things, everything starts to fail...water pump, rad, etc etc. The top and bottom tanks are sealed by orings, the water pump by carbon seal.

Andrew,
when i did my last 4wd trip i noticed it was getting very hot
and overheated.i was towing a camper trailer as
well.and it wasn't
a hot day at all.Since replacing the thermostat it doesn't seem to overheat anymore.i have checked the oil throught the dipstick
and it doesn't look milky at all.still nice and black.
Thanks for your response
Don
