I have stuffed the grill with Screwfix lagging and it certainly makes a difference, Have got a Renault 890C thermostat in reserve but my thermostat appears to be working as per spec... if it aint broke.............. I have not done the battery mod, I did have to fit a new battery after buying the car but to date have not been stuck despite many many short (less than 2 miles) journeys. Occasionally she's a pig to start, I have to watch the glow plug light like a hawk, start immediately and keep cranking till she fires which can take a frighteningly long time. The thermistor's readings are also part of the idle revs and emission control systems (God bless software) Placing a 22K resistor in line with the thermistor appears to tell the computer that the engine bay is 20oC less than true. (assuming the thermistor is a NTC 3950 (this is the closest match I can find relative to the small data set in the ws manual) Extrapolating the figures from the workshop manual and then restricting the data set to the relevant range gives the following; (sorry can't find out how to insert the graph) (At 40C the ECU will think it's 2C, at 20/25 around -1C etc. (with 22K resistor inserted)., within this range the thermistor is fairly linear So my thoughts are there is going to be more diesel in the cylinders than is optimum.... Thoughts ????
