2.7 turbo diesel terrano 1994, everytime i go out in it i need to top up the coolant but no obvious leaks when it sits in the garage? never seems to lose more than a litre, did one trip the other day around 150 kms and topped up 1 litre, did a 40kms trip the next day and had to top up a bit less than a litre, never seems to use any more than that, temp guage sits half way all the time and no warning lights come on.. i am not sure if it head gasket or not, genuine 130,000kms from new.. what else could it be and is there a way of telling if head gasket for sure?? thanks

check the pipe hose clamps in case they are loose and dripping

that too, but sounds like a head gasket to me, about to give out big time.

what colour is yr oil if its going creamy definatley a headgasket other option is go to repco and get a tee kay head check or get yr local mechanic to do it for you can be expensive to buy it for a one off check

actually did an oil/filter change last sunday, oil was as usual, black, not sludgey, and still appeared in good condition, no signs of milky looking oil, also did a coolant change and that was perfect green, this is why i dont know if it is head gasket or not engine runs perfect and as usual, just dont know where the water is going looks like i will need to book it in for a check..

have you checked radiator cap and radiator for pin holes ?

I think I'd be assumeing the worst muskie

well must have been an airlock or something in the cooling/heating system, seems fine now since topping it up, will monitor it though

i suggest looking at the radiator cap and hose to the overflow bottle as it is only 1 ltr each time it sounds like the ammount that would normally expand into the overflow bottle and then suction back into the radiator as the collant cools down lot easier to start checking these items first after that get the sustem preasure tested by an expert
cheers and lol

that is exactly what the problem was been fine now for a week so i assume everything is now ok, but i will keep an on on it.. thanks

also when you replace the water and antifreeze should always run it up with the heater on or you can get a airlock in there also
