Hi Guys ....I have a question regarding my 1992 Isuzu bighorn , I think it has the 4JG2 engine ? it's the 3.1 turbo diesel engine .My question relates to the engine using a small amount of water ,it seems to use approx 1.5 litres of water and then it seems to not use anymore, it doesn't overheat at all but its just never done this before ,in the past its cooling system has always retained the full amount of water and never used any .......I have had it to my local garage/workshop and they pressure tested the cooling system and found no problems with it ,it was holding pressure and it had no leaks ......I have had the same problem in the past with a Honda civic and eventually the civics head gasket blew ,I was wanting to know if anyone has experienced the same problems with their Isuzu 4JG2 engine and I would appreciate your input on the subject ......thanks and regards Scotty
