TSpark Thermostat Replacement
The 156 16v Twin Spark thermostat is mounted at the opposite end to the cambelts ... i.e. the rear of the block, and underneath the intake pipes. Before replacing, my temperature gauge struggled to even get to 70°C especially on a motorway run. In traffic it would climb to 90°+ and the cooling fan would cut in as normal. But for me this indicated a thermostat stuck in the open position. Long term this would affect my fuel consumption. Now from cold I can watch the temperature slowly climb up to around 90°C, when the thermostat opens and the temperature then drops again as all the cool water in the rad starts to circulate. It will momentarily drop down to just above 70° and then stabilise to around the 75°-80° mark, depending on traffic/driving conditions.
