jimmy_neutron Posted July 16, 2008 Share Posted July 16, 2008 a year or so ago my engine was running cold. I traced this to a faulty Stat which was not fully closing. After i changed the stat it ran at 2/3 the way across the temperature guage. I calibrated the guage by removing the engine temperature sensor and using a thermometer etc. I found that 2/3 was about 91' and that vertical on the gauge was about 85'. As the stat doesn't open till 88' i thought it must be the guage at fault and did nothing about it. I always planned to fit a VDO guage, but aint got round to it yet. Everyone on ere talks of an 88' stat going into a 200tdi. However by accident i looked on page 3.1 in the haynes manual and it clearly says that it should be an 82' stat and my temp guage seems to agree too. Any opinions ??

Lars L Posted July 16, 2008 Share Posted July 16, 2008 Yep, Haynes must be wrong... My parts book for Disco 200Tdi says 88 degrees and nothing but. That is what I put in when overhauling the engine and the VDO meter shows a wee bit before 90 degrees. Quote Link to comment Share on other sites More sharing options...
western Posted July 16, 2008 Share Posted July 16, 2008 200Tdi should have a 88 degree stst fited, I've tried a 74 & 82 in mine & found the heater wouldn't give hardly anything & engine was running to cold, my temp gauge on a good run sits just left of centre. only 1 listed for Defender 200Tdi engine in EPC LR part ERR2803 2500 cc - L/R - 4 Cylinder - Diesel - TDi - Turbo - 11L - 200 TDI - 88 degrees C Quote Link to comment Share on other sites More sharing options...
Ex Member Posted July 16, 2008 Share Posted July 16, 2008 Based on my VDO gauge... The 88 degree thermostat opens at 88 and closes at 82..... These are not Swiss watches. Quote Link to comment Share on other sites More sharing options...
