Temp Sender 300 TDi engine swap from 200Tdi
This was a project Defender i took on which was not finished correctly by the previous owner, among a host of other things when the engine was eventually running I had a problem with a higher than expected reading on the engine water temperature gauge, initially i thought it may be a faulty thermostat or a blown cylinder head gasket, however, it seemed to be running reasonably well, the thermostat was removed and tested, the engine temperature was checked using a digital laser thermometer which confirmed the engine was not overheating.
Turns out there are two types of sender for the 300tdi, one has a Green band and one has a Black band, the correct sender in my case was the one with the Black band.
I fitted a new sender with the Black band (purchased from Steve Parker 4x4) and its working correctly now, In my case a Green band sender had been fitted which makes the temperature gauge read incorrectly high.
I’ve removed the viscous fan and in the process of converting to an electric fan, i will post up how this goes.
Cheers
Jock
