Question about 1999 Cadillac DeVille
I have already tried bars leaks head gasket sealer it only starts saying engine coolant hot after 15 miles of driving it with the ac on outside temp 105 f degreesone time i drove it 52 miles no problem what so ever istill dont think is a blown head gasket no white smoke out of tail pipe commpression on all cylnders 160lb no water on oil new water pump new radiator new thethermostat dexcooll antifreeze installed iam puzzled .
Computer glitch , have it checked for DTC'S - diagnostic trouble codes . Not all codes turn on the check engine light . Plus DTC'S for the BCM - body control module won't turn the check engine light on at all , could turn on a yellow wrench symbol on the insturment cluster .
Stop putting head gasket sealer into the cooling system , could clog it up.

hi... it all depends on the colour of the smoke... usualy blueish smoke will mean it is oil burning and your piston rings may be getting worn if it is black then it might be running too rich etc.. a little bit of water is fine infact usualy it is a good sign that your engine is not running rich or lean so it is pointing towards oil seals... also if it was running rich it would probably do it more when it was cold
