alfa 156 @L TS cooling issues when moving slowly - fan not coming on
hi guys, hoping you can help with an issue I hae with my alfa 156 2L twin spark.
I had a new radiator fitted by a garage. Worked perfectly well when ever was travelling at speed and engine was cool as expected, howeer I was stuck in traffic for the first time in weeks and the car overheated.
I checked out under the hood and noticed that the radiator fan connections were not attached. this may have been an omission by the garage - they said they had checked the thermostat and fan so who knows.
anyhow, I hae a few questions I hope you can help with:
given that that there are 2 connectors for the radiator, and both fit each others socket, which wires go where - sockets are next to each.
thermostat appears to be working correctly as car stays perfectly cool whenever there is air passing through the radiator. how can I check that the radiator fan is working correctly? I've had the car up past 90 degrees and the fan does not come on. I believe disconnecting temp sender should have fan run continuously - where is the temp sender?
the fan relay was changed a few months back and all the connections are clean and dry. I believe there is a way of turning the fan by removing the relay and running a wire across the terminals. can someone tell which terminals need to be connected as I dont want to blow anything.
I have a multimeter if that is what is required to test it but i know very little about how the colling system works and the sensors involved and cant seem to find a haynes manual for the 156 which can explain how everything works.
thanks for your help in advance - its a great car and I want to get it running correctly so the overheating is an issue.
