156 2.0 t/s Cooling issue
Had a look at a mates 156 today. When we started it up from stone cold, within a minute the electric fan kicked in?? temp gauge hadn't moved.
The rad and hoses stayed cold but the fan kicked in and out every few minutes and the temp rose to normal operating temp.
When I try to think what's up, nothing makes much sense.
I've had thermoswitches fail on other cars before, but the fan usually fails to kick in and they over heat, not stay on all the time.
If the thermastats stuck closed, the engine's not overheating?
If the thermastats stuck open the rad/hoses stay cold, but the temp gauge climbs steadily?
What's telling the fan that the rads hot when is not?
