  1. Oh dear sorry to hear that. Had the problem with a broken glow plug myself but as the head was going to turner engineering for reconditioning they managed to remove it. I believe there is a special/technique but thats no help now!

    Just a thought could the head be repaired by a skilled aluminium welder and then skimmed? If not I believe there are new 300tdi heads still available which may be a better bet for long term reliability, that should be good for 250,000 miles or so.

    When I had similar symptoms on my 200tdi I found the head was slightly corroded around one of the coolant passageways this was causing the system to pressurise and the head gasket to blow. Even a re-skim didn't remove enough material to cure the problem so I had to source a good second hand head and have had no problems since. Would also recommend an elring head gasket and new head bolts. Maybe worth getting new/recon injectors at the very least have yours tested.

    I know this is going to be a relatively expensive job but done properly should last for years.

    Good luck and keep us posted.

  2. Can't pretend there's a lot of legroom for second row passengers but I've always managed and I'm 6'2", just make sure I stop every couple of hours on a long journey for a leg stretch. As said above its one of those compromises thats worth putting up with in my opinion.

    Exmoor Trim manufacture a kit which allows the seat backs to positioned further back which allows a slightly more comfortable seating position although not sure if this can be used on newer vehicles.

  3. One thing to try is to go on a run then leave the engine to cool completely (eg. overnight). Then slowly release the expansion tank cap in the morning. If there is a large hiss of air I would say the cooling system is over pressurising and the most likely cause is a faulty head gasket.

    You also mention your top hose split, another sign of excessive pressure?

    Another thought, can you actually feel the top and bottom radiator pipes are warm when the temp is showing 120 (proving there is actually flow through the rad). I wouldn't expect you'd be able to hold a rubber hose for long with 120 degree coolant flowing through it!

    I'll test the resistance of my gauge next time I go for a run.

  4. Surely if the temp was really 120 the coolant would be boiling? Sounds like a wiring issue to me.

    Can you see the point when the stat opens?

    On my 200tdi the gauge (vdo also) gradually rises to about 85 then suddenly drops back about 5 degrees as the stat opens and cool water is allowed to flow through the radiator. It will then gradually rise again and settle between 85-90 depending on how hard the engines working.

    Hope you sort it.

  5. Well just been out christmas shopping today with a different but still 88 degree stat in and its running noticeably cooler. Success!

    Highest temp I achieved was about 88 so much happier with this. Can't wait to test it in warmer conditions but more confident the cooling system is working ok and it was just the stat which was creating a higher operating temp.

    Another thing did become apparent though. When I switch the blower on full the temp gauge instantly rises about 2 degrees suggesting an electrical fault somewhere. Only seemed to be the temp gauge affected. Poor earth?

    Thanks for your help everyone will keep you updated.

    Cheers Mark

  6. I read on here somewhere that 82C was an option for the 200tdi, but nearly all were fitted with the 88C stat.

    I serviced my coolant system lately and thought that i would replace the stat whilst at it. I bought one - Waxstat 88C (i beleive they make them for land rover). I fitted it and ran the engine up to temperature. It heated up quick enough, but kept going! The temp guage went to the far right of the white section on the guage. In the summer, it usually sits at midway, in the winter, just to the left of midway. I took the new stat out and tested it - it didnt open until 95C and was fully open by 97C! Shouldnt have wasted my money as the old stat was working perfectly when i finally tested that (fully open at 88C).

    Funnily enough the one I've been running is a Waxstat bought from a land rover dealer! It too didin't start to open until 92/93 degrees and wasn't fully open until 95 .

    If the genuine stat isn't reliable then where do you get one?

  7. My 88 110 has a defender 200Tdi and when I got it the temp gauge sat in the middle I changed the Stat as I though tit might be the reason for slow heat up and it now sits just of the Red, even tried another stat but the same so I think I have the same issue as you!

    Sounds like a similar problem. Doesn't leave much margin for error if the needle is just hovering below the red!

    Must be that thermostats are pretty variable. Will let you how I get on tomorrow with a different stat.

  8. Middle of the gauge is the normal operating position, or always was when my 200Tdi still had the old gauges.

    Re. Thermostats, don't bother with anything but genuine ones.

    Sits well past the middle almost into the red, well it did until I installed a VDO gauge, now runs at 90-95 but not had the chance to work it hard in hot weather yet.

    Have just fitted a different 88 degree stat to see if it makes any difference.

  9. further there is ONLY a 88 degreestat listed in the LR parts books/Microcat for all markets, if your temp gauge is reading incorrect then the sender unit needs swapping or fit a VDO temp gauge with a matching sender unit.

    Ok then maybe just me clutching at straws.

    Have fitted a VDO gauge but recently temperature rose to 95/96 this whilst steady motorway driving in winter.

    Suspect that working hard in summer it would significantly exceed this.

    Just tested the three 88 degree stats in my possession and the one I'm currently using (genuine item) does seem to open a touch later than the others. Although I'm not sure its enough to make any difference I may as well give one of the others ago.

    Only other thought is that the britpart radiator I fitted doesn't seem any where near as heavy duty as the original item although had the same overheating issue with the old rad?

    Failing that might try a new genuine water pump although they seem a bit pricey.

  10. Had a long standing cooling issue with the 110 and now believe it may have originally been fitted with an 82 degree stat? (Heard rumours this was once an option on some 200tdis). When I changed the original a few years ago I never checked the rating and threw it away so will never know!

    As it was in the depths of winter it seemed fine and the engine warmed up much quicker. However in the warmer months it transpired that the gauge was reading almost into the red. I am now thinking this could be because the gauge was originally matched to an 82 degree stat.

    Decided to fit an 82 degree stat from a disco which i had lying around in the shed just to see if the reading on the gauge returned to normal.

    Just noticed the disco stat doesn't have the toggle through it which I assume is there to assist filling the system and avoiding airlocks.

    Anyone know why the disco doesn't have it and whether I should modify it before fitting or will it be ok as long as I fill up carefully.

  11. Having had a few temperature gauge issues with my 200tdi 110 I swapped the original gauge for a VDO gauge and sender.

    Engine now runs between 88 and 90 deg, rising to maybe 92 when working hard eg. towing uphill.

    It generally takes about 5 mins driving to reach operating temperature although I did notice in the extreme cold this winter (below -10) it struggled to get over 60.

  12. Iirc on the disco with air con the coolant temp had to be 110 deg c before the a/c fans switch on automatically to help out, this was on a 300 auto i owned and im sure td5 is the same.

    In my series2 i have a cappiliary gauge from a a mini fitted cost about 20 quid new from e bay.

    Just been out for a drive with the standard landy gauge fitted. After 10 mins temp is past halfway on the gauge - the same reading as it was submerged in boiling water!

    I'm sure there must be a problem with the cooling but the system has been replaced (rad, pump, thermostat, gauge and sender) which makes me think the engine might be generating too much heat for some reason??

    Any ideas?

    Might get the injectors/pump reconditioned but as engine runs very well (a touch of black smoke when accelerating hard but will do 80mph) this is probably money down the drain.

    Suggestions welcome.

    Cheers Mark

  13. check your idle RPM too, needs to be 750 to 800rpm, if to low the oil light will flicker. a new switch should cure your current problem, to test the wire just do a continuity check with a multimeter or test bulb.

    There is continuity between the spade connector on the switch to the the warning light on dash. Guess its new switch then.

    Thanks Mark

  14. Oil warning light came on the other day for first time in 10 years (except when ignition first turned on). Saw it flicker a few times and then it stayed on. When I stopped and restarted it was off again but reappeared after 5 mins. Engine running fine no oil loss or strange noises.

    Have tested the oil pressure by removing switch and screwing in pressure gauge. Getting a reading between 25 and 55psi (manufacturers recommendation) so pretty sure its either the switch or wiring. Just wondered if there's an easy way to test the wiring before I splash out on a new genuine switch.

    Cheers Mark

  15. By design though. All car makers do this with their temperature/pressure gauges & senders. Generally people are stupid and would panic over the normal temperature variations that actually happen. So they make the gauges non-linear, they'll only move if there's a heat problem big enough to be outside the normal range that the engine would experience during driving.

    Some aftermarket gauges are more linear, and you can actually watch the engine heat up and then cool down as the thermostat opens, for example.

    There's also the variation that will occur between manufactured gauges/senders, two Land Rover gauges would probably read slightly differently off the same sender, or vice versa.

    So best stick with original gauge and not be worried by fluctuations in temp? I guess by the time it hit the red it would be to late to worry as the engine would be cooked!

    I'm only worried as vehicle has blown two head gaskets although since changing to elring gaskets on this and a mates vehicle we've not had a failure.

    Cheers mark
