since buying my 145 cloverleaf last year the coolant temp has never been any higher than about 80 C (just marginly below the line). reading some of the posts on the forums is seems that the engine running temp should be around 90 C.
over the last couple of months the temperature has been dropping untill it reached around 55 C so decided that some action really had to be taken. i decided that the most reasonable thing to replace would be the thermostat valve. this was done a couple of days ago and the running temp is now back up to 80 C!!
reading through the maintenace maual the opening temerature of the thermostat valve is 83 +/- 2 C so this would, i think, correspond to a running temp or around 80 C. am i wrong in this assumption or missunderstanding the system!!??!!
the car temp will sit at 90 in traffic so the fan and fan sensor are working fine. fuel consumption is much better too. which is always good. does anyone know the resistive values for the NTC sensor on the thermostat.
any comments would be appreciated.
