Re: 77 yellow gmc swb
Got my fans on ,so I fired it up but the fans never came on till after I shut it off , I need a lower degree thermal switch or maybe mount it in a different location in the head/intake ? cant remember where the switch even came from but I thought it was a 180. also found out when they did come on the shoud neads some trimming around the fan holes , try again tomorrow !
