Question about 1998 Cadillac DeVille
Runs rough at startup then reaches temp around 198 and smoothes out and runs very nice. temp will run up when sitting for 5-10 min but when I go agian it comes down and runs fine. Service engine soon is on and Autozone cmptr reads elec temp sensor that I cant locate. I just bought it 2 weeks ago and it does have some white smoke that clears when it wams up so I dont know if it was condensation. It is losing about 1/2 gallon antifreeze per week. Do I have blown head gaskets? Will any leak stop work? Thank you.
Yes it is headgasket. Mine had same problem. Yours might not be severe as of now, you can try these other solutions. THERMAGASKET... Which you can buy online, and get your money back if it does not work... And stuff in a bottle at Autozone Repair headgasket with NanoTechnology! I would try and sell it quick, because these engines are very costly to repair and most mechanics wont even attempt headgasket repair, and plus you have to TimeSert the block...
