Hi all. I'm very confused, a whole bunch of threads seem to have completely disappeared - hence the new one. I had huge problems getting my heads off, eventually resorting to all kinds of fun and games to get them off.... Anyway, I've just had a call from the machine shop telling me...

Hi all. I promise, I have tried to search for an answer to this question, but I've not come up with anything useful.... In a nutshell, I'm going to attempt a HG replacement shortly, but having never done one, I'm after some help on what bits I need to buy...? And any guidance on where to buy...

Hi. I don't know where you are, but when I had LPG problems I eventually got them sorted out by going to an absolute genius of a bloke, Simon at 'Yorkshire Autogas' - www.lpgc.co.uk. They are between Wakefield and Doncaster. I'd been back and forth to a local 'LPG specialists'(!!!?) in...

If you're going to take the trouble to create a false quote with my name on it, please ensure you punctuate correctly. I've heard that you need three eggs in the header tank, and the bucket of sand needs to go in the top hose.... didn't I hear that from you...? That bed you got out of the...

I'm sorry I wasted 5 mins of your life, but the point I'm trying to get to is to get various opinions on the same topic so I can attempt to make a considered and educated decision. Wammers has expressed just such an opinion just now, and I've had 2 or 3 other suggestions in my other thread...

Hi all. I figured a new thread would make sense. I've had some help on another thread about my overheating problem for a 2000 4.6 V8 P38, and I'm now thinking I've either got a blown head gasket or a cracked block. I'm thinking of my next step, and I'm considering using one of the additive...

So, taking all of the replies into consideration, I'm now moving towards thinking it must be either a failed head gasket, a slipping liner, or a cracked block (joy!). I've just got another car for the missus, so I'm going to hang on to her old one until I've sorted the Rangie.... so it is now...

The configuration of our engines is obviously a bit different.... on mine, the thermostat is located near the bottom of the rad, and is like a cream coloured plastic cylinder with 4 pipes coming off it. You can't get to the actual thermostat to remove it, it is sealed-in to the unit. I guess I...

I checked the spark plugs last week, looking for just that, but all plugs looked normal to me - and the same as each other. It has had 2 new thermostats. The one I fitted was from Island 4x4 on ebay. I paid £20. That is the current one. I still have the previous one, but I don't think...

Now you mention it, yes. Not always, but I have noticed on several different occasions it hasn't started 'first touch' like it always used to.... Does that tell us something?

Water pump is new....

I'm not sure.... I did notice a lack of heat once, but I can't be certain it was every time... You said you 'had' a similar problem.... how did you solve it? Test runs are long enough to get up to temp, but I've been cautious about how far from home!! Certainly a few good test runs in...

My interpretation is that the top of the rad can get hot because of the water coming in from the 'top hose', but can't circulate properly through the rad until the thermostat opens... Water pump is new. Rad new. Confused. I'm increasingly thinking it must be a failed HG, but I can't...

Ok, I've done a bit more.... - I've completely disconnected the LPG vaporiser and capped off the coolant pipes for now. - Having inspected the hoses, one looked a bit knackered - the one with a 'U' shape coming off a t-joint - header to thermostat I think... Anyway, I've changed that (once I...

I forgot to ask something else.....! If my overheating problem is down to some kind of blockage (causing poor circulation), is there any kind of 'dislodging fluid' I can use to clear the blockage?

Managed to get my OAT coolant from the local motor factors this morning. I was amused to see his blank face when I asked for it... he'd never heard it referred to like that before either (I felt a bit less dumb). A quick read of a label later.... it made reference to 'Organic Acid something or...

Is it as simple as 'if its pink its ok'? - Or is there such a thing as non-OAT pink? What does OAT stand for? Sorry if these are dumb questions...! Delightfully, I've been using blue stuff for a couple of years.... I guess another flush is required! Does pink taste any better? - I always...

Hi all. I won't bore you all again with my overheating problem, but I've run out of antifreeze and need to get some more. I've read various things suggesting that the wrong antifreeze could cause problems.... I'm guessing that if I go to my local LR dealership I'll be screwed on price...

So gas can get in via the LPG vaporiser?? Would I be able to smell that in the coolant header tank? I guess it is the lesser of the evils.... I can reasonably easily bypass the vaporiser for a while to test, so I'll do that later.... If it is a head gasket or cracked block, how can I tell?

I'm not sure it rings a bell, but it certainly has me confused....:I've done new rad, 2x new thermostats, attempted fastidious coolant system bleeding & filling, and coolant level is fine (until it overheats and blows out of the cap!) though possibly rather diluted at this stage. I suspect a...
