I've looked for anything that can point me in the right direction, but all I've found is that the yellow light with the words "check engine" means either the oil pressure is low or the coolant temp is too high. My problem is that my oil is topped off and the coolant in the resevoir hasn't gone down. No I dont have real oil pressure or coolant temp gauges and yes I'm getting there, but right now it doesnt seem like either of those should be tripping the light. The light comes on as soon as I start the engine which makes me think the circuit that the light is on grounded out or something bc even in this heat it shouldnt be overheating before its running. The only thing I can think of is that the cooling system might have a leak and instead of sucking in coolant from the resevoir when it needs more that its just sucking in air through the leak. when I pull the radiator cap off when the truck is cold are you supposed to be able to see fluid in there? short of draining it I'm not sure how to see how much is actually in there and I havent had a chance to drain it yet. The temp gauge was *working* but now either is bottomed out like its off or way towards the cold end of "NORMAL". it's starting to tie my brain up in a pretzel, any help would be appreciated
