1994 K2500 Suburban 6.5 turbo.
So after My suburban is fully warm after an hours long drive on a 90 degrees day less than 5 minutes later I had to move it after shutting it down. I noticed the glow plug light ran a normal 15 to 20 second run time I could also hear the glow plug controller click on then off like normal. Everything else about the truck is normal and runs great. I checked it after several other drives and it always runs a normal glow time. Is this normal or should the glow time be much shorter or not at all when warm. Other diesels I have had never did this. Thanks
