Over heating 1996 cobra
The car is overheating I replaced the
thermostat and reservoir cap. I don’t see any
leaks. Losses coolant within 10-12 miles.
White smoke from exhaust also some oil on
#1 plug when I changed them.
White smoke out the exhaust is not good, usually indicates either blown head gaskets or a crack in the cylinder heads. You can run a Block check yourself just buy the kit from your local parts store and follow the directions. Or have your favorite shop do it.
