Having problems with your 1990 Honda Civic ?
I HAVE A 91 HONDA CIVIC AND HAVE HAD SOME OVERHEATING PROBLEMS. I HAVE CHANGED THE RADIATOR AND LEAKING HOSES. NOW TH PROBLEM IS WHEN COLD THE CAR WILL START NORMAL BUT AFTER I DRIVE IT A WHILE IT AND STOP, AND RESTART IT WILL HAVE A RUFF IDLE AND SOME WHITE SMOKE COMES OUT THE EXHAUST. IF I DRIVE IT THE SMOKE WILL STOP. I CHECKED AND THERE IS NO WATER IN THE OIL.(NOT MILKY). IT DOES SEEM IF THE CAR IS OVERHEATING BUT THE TEMP GAUGE READ NORMAL.
White smoke is burnt coolant. Take the car in and have a pressure test done on the rad. It's probably going to lose pressure slowly so get a compression test done on the engine. This will most likely show a leaky head gasket. That is the most common cause of white smoke out the tail pipe and could also cause your other symptoms. Hope this helps.
