Thread: D1 300TDI overheating issues Broome Please help!

"With the cap off and i give it a rev and back to idle water gushes back out the top of the expansion cap so I don't think its the pump."

Something is up there. My understanding is you can rev it at stand still with the cap off and it won't go everywhere. Is the coolant level half way up the expansion tank when you do this? And it rises all the way to the top and out?

If I had to guess, I would say check the thermostat. Possibly a blocked radiator.

If you feel the top and bottom radiator hoses, is there a significant temp difference?

So when you rev it the level wont change.

When you go from 3000 to idle by taking your foot off it fountains up but returns to the correct level. dose not overflow out of the tank.

Could be an air lock in the thermostat housing.
My Engine saver was intermittently going off.
The coolant ejector was blocked. Cleaned it out and now I can see a jet of water shooting up in the expansion tank.

The viscous coupling can be bodged up by taking the outside edge of the spring out of the retainer and turning it Anti-clockwise until rests on outside of the retainer. This will give it more lock up but will suck up some horsepower and fuel economy will suffer.

Water will shoot back through the expansion tank when revved if the thermostat is not open. If you let it idle up to operating temp then there should be hot water flowing through the expansion tank.

What is this coolant ejector you speak of????
Is that that little black thing that helps to remove air from the system? where is this located???

Stephen, Whatever you do don't leave Broome with a dodgy cooling system. I am aware you have time constraints however, it's not worth it. I live in Derby and travel the Kimberley extensively and am not aware of any competent radiator repairer O/S of Broome. There is a NATRAD service in Broome at Cnr Tanami Dr & Florence Way, Blue Haze. They would be the best tip but being a NATRAD service center they would be as dear as sin. I used one in Sydney once and it cost me 1k. As far as LR mechanics I don't know of any. What might pay you to do is drive around Broome and keep your eyes open for LR's and bail up the owners and ask them where they get there LR serviced. There are a few there. If the weather is fine tomorrow head down to Gantheaume Pt beach Just about every 4wd in Broome will be there, you might catch one there.
If i can be of any assistance you can PM me and i'll give you my phone number.

Cheers
Rob

Agree, need to check for air at the top of the thermostat housing and ideally check the thermostat is working. Be very careful undoing the thermostat housing plug if the engine is hot though!!!! Don't want an explosion of hot coolant on your face!

I could be wrong, but I don't believe there should ever be any kind of "fountain". Coolant should flow through the tank, but the level changing significantly seems odd to me. More reasons to suspect air and thermostat issues. I'm open to being told otherwise though and concede that if the thermostat hasn't opened when it should have there could be excessive pressure and cause weird effects like level changes.

Ejector hose is the think black hose that runs from thermostat housing back to expansion tank and radiator via a join.



I don't think this could be causing the problem though.

TBH it could be leaking head gasket, but you should check the more basic items like thermostat first. Also, top and bottom radiator hose temperatures? Bottom hose should be luke warm. If the top hose near the radiator end is not hot (or not as hot as the water pump end), that also points to thermostat not opening.

Yep that's it.
Located to the left of the AC compressor sort of floating.
hoses go to expansion tank, thermostat housing, radiator.
Mine was blocked, thermostat to expansion tank.
I used wd40 to soften the crud and then compressed air. It is now free flowing in all directions.
