View of the thermostat ( 87° ) & thermosat housing and the infamous temp. sender # 2 (BLUE)

The Westy trouble maker's..., change those damn parts, PERIOD. (Those are 30% of the van problems)

The Blue temp sender #2 (on the left side of the thermostat housing) is for the ECU or fuel injection mixture, the black temp sender #1 is on the front of the thermostat housing (90deg of the blue one) and this one is only for the front temp gauge in the dash, The red coolant level light in the dash (behind engine temperature gauge) is directly attach to the gauge (on top) on the expansion tank. For now I did not find any indication about the location of the so call buzzer for the oil pressure sender on the Canadian version.
