Sometimes it seems the fans dont kick on when idle speed when i put my ac on the secondaries come on..seems its running kinda hot and is there to check relays easier? i mean there are three to check and i moved them around and checked um on the fog light connection and they all seem to work when i use the fog lights.its a 1996 Z28, Also i had to replace my radior cap was letting to much fluid out into overflow,could my coolant mixture be wrong for the cap to release presure? would that cause it to build up more presure? and how could a radiator cap go bad????? thanks guys

high flow bumper oil, muffler bearings,and a new combogulator swith,and high speed wipers,heh

Could have a head gasket going if you start to see to much coolant going into the over flow. Does it still have to much overflow with the new cap? Raidator caps should be changed every 2 years or every other coolant system flush. I think though that 96 GMs have the orange coolant so i would read the owners manual before draining the coolant.
