Very little heat coming from heater. All good info, thanks. Definitely need to check my grounds anyway. Once I’ve worked out how to stop the alarm going off, every time I disconnect the terminal... To stop the alarm going off you just need to ensure you disarm the alarm and then disconnect the battery before the alarm self arms again. Link to comment Share on other sites More sharing options...
russelld Posted May 8, 2019 Share Posted May 8, 2019 The K series S2 only uses one of the sensors for both ECU and stack the other sensor is not used. The black one is the one that does both jobs : https://www.eliseparts.com/products/show/33/158/ecu-coolant-temperature-sender-s2/ Link to comment Share on other sites More sharing options...
Lithopsian Posted May 8, 2019 Share Posted May 8, 2019 S2 now? Well that simplifies things. See what happens with the new sensor, then I don't know whether it is better to hope for a stuck thermostat or not because it is tricky to get at. Link to comment Share on other sites More sharing options...
Caligarinet Posted May 9, 2019 Author Share Posted May 9, 2019 I had read that the S2 only used one sensor, but mine definitely has a black and a blue one fitted. Im fully preparing for skinned knuckles and lots of swearing to change this thermostat. 😬 Link to comment Share on other sites More sharing options...

The blue one is not used for anything on the S2, although I believe it is an entirely functional sensor. Link to comment Share on other sites More sharing options...
Martin R Posted May 9, 2019 Share Posted May 9, 2019 As above the Black one only does anything on an S2 K series. Without the Blue you would use a lot of coolant. Link to comment Share on other sites More sharing options...
