I really hope your right - I have put another thread on here, as my heaters are still cold, hubby is trying a new thermostat today, in the hopes that this is causing the problem. The pipe from the thermostat housing to the rad is warm but not red hot, and the one from the bottom of the rad is...

New update, water flow seems ok now HOWEVER thermostat housing is relatively HOT the pipe from the thermostat housing to the rad is warm (but I can hold it) but the pipe from the bottom of the rad is cold. BUT when the engine is turned off, that bottom hose gets warm!!!!! Could this be that the...

Hi I hope so too. The heater matrix has now been flushed both ways, and there was a clear flow! Had the inlet pipe from the bulk head to the heater matrix off today and the water trickles, rather than "pumps" out, even at high revs? It just gives coughs and splutters the higher the revs get...

Ah right! But theres no drips, however I have been told that they may not work to full capacity and therefore not beable to force the water round correctly. Would that be true?

Thanks for that - I though I was losing the plot then!

I'm about 10 miles from Bury!

We are near Burnley in Lancashire (well between Burnley and Rochdale). Bit of a way away from Cheshire???

I think that is going to have to be the way. I am going to try a new water pump first though. I have been thinking, and logically speaking, I first off lost my heaters, then the water pump went, then the head gasket went between the cylinder and the water jacket if that makes sense (or that...

I have been told that the head was pressure or crack tested, and also I beleive that the coolant system has been checked. Hubby checked every bloody pipe and has cleaned each one, before head was done, however I think that there could still be rust or something in there!! Is that going to be...

I think the thread you are referring to is mine (Help.....heaters cold on discovery 300tdi). That was the two month scenario, of going through water pumps, thermostat etc, then had to have the head skimmed. I am just so annoyed that the heaters are still cold, but then go aired at 3.000...

So how do I solve it then? I have bled it right (filled up to level in expansion tank, put cap on, filled rad, put cap on, and filled thermostat housing to top, put cap on) also filled pipes in heater matrix and put back on. ran round now for over half an hour, up extremely steep hills...

I thought about the dodgy stat first port of call. But why would it overheat on certain times and then be fine others! The pipes from the thermostat housing to the rad get hot, but the one at the bottom of the rad is aired. The pipe to the heater matirx is hot and the one coming away from it...

Yes water system dropped, fresh water and anti freeze put in! System was bled fine (thermostat housing and rad, and expansion tank filled and bled in the correct manner) Hubby has just done the same roads as me, (after filling the thermostat housing) and also a reall really steep lane, and...

You may have all followed my tails of woe on my Help!!! Heaters cold on Discovery 300tdi thread!!!! I have had my head gasket replaced, head skimmed, and for a very short time the heaters were aired. HOWEVER yesterday I took her (being my 300 tdi) on a 16-17 mile round trip, relatively flat...

You were right - head gasket was on incorrectly

Well, low and behold, we handed the head over to the pro's and it was indeed warped. They had to take a mm off it!! It is now all back together and working fine. Head gasket had indeed failed, head had indeed warped, and now we have lovely warm heaters!!!!! (hopefully permanently) So after all...

Once the head has come off again (as the oil kept leaking out) the head bolt snapped and the front tiny corner is quite clearly seen on the corner of the head as the offending gap!!!!! no where else. New torque wrench, new gasket and cleaned the head, going to put back on!!! We only went 200 yds...

Think we have sorted it - looks like the torque wrench we used hasn't torqued it properly. Going to re-do tomorrow - will post once we have sorted!!! Fingers crossed x

Well head gasket replaced, and all put back together. bled up and quick drive down the road, got 300 metres and there was a "pop" and low and behold the car cut out and there is an unbeleivable amount of oil seeming to be coming out of the area of the head at the front next to the thermostat...

HI, Thanks for the replies. I have only just read them, unfortunately after hubby has decided to take head off. He has taken it off, but all the bolts for the exhaust manifold etc were able to be undone with his hands!!!! That just obviously wasn't right to start with. When the gasket came off...
