My 1989 90 has developed a strange fault with the water temperature gauge and I would be grateful for any advice please.
For about the past year, the needle on the gauge has barely moved at all regardless of conditions. I put this down to the 200TDI being a cold engine rather than any problem.
Within the last week or so, before I even start the engine, the needle moves towards the middle of the normal range without the engine even running. Engine starts great, pulls well but I now have no faith in the gauge.
Going to order a new temperature sender (Steve Parkers one - designed for Discovery into Defender engine conversions) but in the mean time, is there anything else I should check?
Thanks,
Andrew.
