Hi there I have 2 noises in my 1988 k1500 5.7l tbi.
The first one I noticed going about 70 mph you would hear a screeching/whirring noise for just a split second then immediately it goes away.
Engine warning light comes on.. after turning truck off and back on again the light goes away although the noise happens here and there coming from the engine bay?
Secondly I was traveling up an asphalt road while almost reaching the top of the hill I heard a rattling metallic sound almost like clanking while under load? Sounds in the engine bay although lower and more towards the cabin maybe...?
ANY HELP WOULD BE MUCH APPRECIATED
