Hi guys, we have an 04 3L diesel patrol and it has been running low on power getting up hills for about the past 8 months. We were told it was probably the filters at first which we had changed. The car has always been serviced religiously at every 7-9000kms as it is out work truck we keep up to date with everything. So long story short, it started making a dripping noise every time you turned the car off (this was straight after a coolant flush they did). After this, it overheated once about 4000 kms into the time after the service and coolant flush. There was never any drip marks or any evidence of a leak anywhere. Took it back to mechanic after overheating to which they did another coolant flush and straight after that we went to out first job about 5 kms from mechanics and it spat coolant everywhere and from them on has been gurgling like crazy!! The gurgling is definately coming from coolant tank too. We took it straight back to mechanic and they basically had no idea and told us to trade it in.. So we have taken it to another mechanic who said it could be an air lock which is what we were hoping for but unfortunately it is not. So it's either (from what I am told) the head, the block or the gasket. I am thinking of putting a 4.2 engine into it rather than buying a new car as we have put a lot into this. I have heard the big symptom of a cracked head is blowing white smoke which our car doesn't ever blow any smoke at all. Just wondering if anyone has any ideas at all before we go ahead and spend money on this. Thanks all!

Hmmm. I am no expert but It sounds to me like a cracked head or head gasket or both.

My wagon (2003 model) cracked a head and spat its coolant so I replaced the head to have it happen a few weeks later again.

It was only after replacing the motor and a heap of other stuff (this is a pilot/escort vehicle that my wife drives and MUST be reliable) that I found that the glow plugs stay on for up to 5 minutes after a cold start. I then put a momentary on/off button on the glow plug relay wire and all has been well for the last year.

My guess would be to do the head/gasket and then do the glow plug mods. use the search function on this site. Some people are using a timer system that seems to be pretty fiddly and a lot of mucking around to do what a simple button will do but the choice is yours. Good luck and I hope that for your sake that Its as simple as a dodgy radiator cap. Probably not though with an alloy head on a cast iron block, they all seem to crack heads sooner or later.

Oh yeah. Welcome to the forum :)

Thanks bog meister really appreciate your help! Spoke to the old diesel mechanic and he agrees that it does sound like a head :( Will do some more research this weekend but for now it's looking like a conversion to the 4.2L. Do you know anyone who has had this done and have they had problems down the road? What did you replace your motor with? Sorry to hear you had the same problem happen twice!! Thanks again for your help mate.

Could be a few things including blocked radiator, faulty thermostat or water pump.

Take it to a mechanic who knows what they are doing. Unfortunately there are not many good ones around.

It could be something simple, get it looked at.

Take it to a radiator works and get them to test for gasses in the coolant. No gasses mean no cracked head, or block, or even a head gasket. Just blocked cooling system.

PS change your mechanic. Where are you?
