Hi, I have a saab 1999 93 2.0 injection non turbo, non air conditioned, which recently burst the main coolant pipe which was weathered. I've replaced this and have since been worried that the radiator fan may not coming on when it should. When should the radiator fan come on. Normal operating temperature is halfway up the temperture gauge. So I guess it should not come on as long as it stays around this. How far up does the temperture needle need to go before the fan should kick in? I've checked the fuses and relays and all seem fine. I've cleaned and dried the connector going to the radiator fan. After a drive i noticed the fan was not on so i opened the bonnet and moved the wires about a little. I left it for a few seconds and the fan then came on, for about 1 minute, but i wasn't sure if it just kicked in or if it was a loose connection. This is one of the few times i have ever seen the fan on. So the fan itself does function. Does it sound like a problem? I'm quite concerned in case the engine overheats and screws up the head gasket. I'm trying to rule things out - There is some sort of sensor mounted on the front of the car just below the grill and in front of the radiator? It's made by siemens and about the size of a 50 cent (euro) coin, What is this? Is it related to the fan functionig? Hope somebody can help - Thanks for the help in advance.
