Stonejag 10 Posted March 25, 2012 I noticed my Meyle one working after a long run the other day so it's obviously fine but not being turned on at the right times. According to the Bentley it's tested (along with the stage 3 radiator fan) by shorting the brown/red and brown wires in the connector to the yellow temp sender so maybe my issues were down to a dodgy sender all along? :shrug: Quote Share this post Link to post Share on other sites

VR6Pete 0 Posted March 31, 2012 All fitted. Lovely job. All aspects of the cooling system now replaced and now leak free :) Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted March 31, 2012 does it come on all the time? mine comes on with ignition and seems to run all the while Quote Share this post Link to post Share on other sites
VR6Pete 0 Posted March 31, 2012 Yep. Should come on with ignition and after run triggered by the 2 pin black temp sensor if hot hot hot :) Quote Share this post Link to post Share on other sites
Stonejag 10 Posted March 31, 2012 Is it wired direct to the switched live from the ignition? Mine doesn't run with the engine on...:( Quote Share this post Link to post Share on other sites
VR6Pete 0 Posted March 31, 2012 My obd1 and obd2 have always come on with ignition... Just as it comes. No direct feed from ignition or anything... The below might be of use to test your yellow sensor.. Assume you've already checked the fuse in the fan control module etc.. Quote Share this post Link to post Share on other sites
