What did you do with your Range Rover today

didnt know anyone else used it, though i guess it makes sense commercially. do you know if it was any better/worse or just 'different'?

Both GM & SAAB used the system and it was in some Jaguars too. I think a simple vacuum servo powered system takes a lot of beating. The only real advantage I can see for the electrically powered WABCO system is that it continues to work with a dead engine.

If the system is not holding pressure, the coolant will always boil.

Rather worryingly I seem to have the opposite. Parked her up last night. This morning before starting I popped the expansion cap off and coolant ****ed everywhere with considerable pressure. I've lent my other car out to a neighbour who was unexpectedly car-less so no backup and winging it in the Rangie. Each journey is an adventure.

I guess sniff test next?

Does anyone know why the p38 has funky brakes compared to just about any other vehicle and why land rover dropped the idea so quick?

Funky?

Possibly because the P38 was so damn heavy they asked a truck manufacturer what they thought. I suspect they ditched it after various garages failed to RTFM (RAVE) and a few bear misses later went for a more standard setup.

Release pressure and the coolant will always spew out of a hot system as the reduced pressure causes the coolant to boil.

No, it was still pressured this morning when cold!

Not used on Trucks as far as I know. WABCO = Westinghouse Air Brake Company. I think they started out doing braking systems for trains, they also do air brakes for trucks.

That's not good news

Sadly, that sounds more and more like a cracked head methinks

Yeah, I am trying to shy away from that but I am running out of alternatives. On the plus side maybe the scrapper head is sound. Only 1 way to find out!

I am going to take a leaf from politicians and just pretend the problem doesn't exist and state platitudes to myself over and over until everyone believes it and then we can all be shocked when I break down on the M6.

No, I don't think it was used on trucks (although who knows if some little ones had it fitted?) vut I suspect JLR went to them for advice and they cooked the system up. I did put two o's in there, didn't I?!

Module 2 just needs a fault clearing.

Now that’s encouraging to hear.

I think you're the first I have heard of on here with a failed EAS module. Good effort!

I love this forum. nearly every issue I encounter has been encountered before and the good burghers of LZ provided advice and solutions. However, I promise that with all the defects, both from the history and occasionally me that plague her - if there is a new issue to discover then like the chemists in Ytterby finding elements, I’ll be the one to find it!

Not as much as I do. Once opened a hose fitting on a turned off Quooker which I then discovered allowed a reduction in pressure causing pressurised water at 110 deg to boil and the resulting steam and boiling water to empty themselves all over my ankle. 3rd degree burns. I was sitting cross legged so bloody lucky it was my ankle!

Otto was doing the same but the heads were fine (got skimmed anyway), it was a blown gasket. Badly between 2 and 4 but also just a seep starting between 8 and the water passage.
As you say, only one way to know for sure and both need the same exploration.

I would say your thermostat is fubar its closing off when the pressure is high and no opening again

Pretty sure that isn't the issue here

I tried popping a matchstick in the expansion cap thread to stop it closing and then went for a drive. I'm now sat in a pub waiting for it to cool down and coolant all over the wing. So it is pressurising and pumping coolant out.

Once it (and I) have cooled down I will refill, take the match out and limp home. Booked the day off as I am going nowhere. I have a compression tester. I'll try pumping air in a glow-plug hole and see what happens in the expansion tank. I fear there may be bubbles.

This is an oil burner. Seems the M51 head cracks before the gasket lets go - usually.

2 thoughts, use a live match strike it and....... 2nd is tell it it's a ford or a VW and not a Land Rover
