Can a bad thermostat cause white smoke?
Not directly, but it can crack or blow your head gasket. (Which will cause white smoke)
Happened to me =(
Heavy white smoke is usually caused when the engine burns transmission fluid, such as when the modulator valve is defective, causing transmission fluid to be sucked into the intake system. A stuck closed thermostat could cause the engine to overheat. If the engine overheated badly and repeatedly, a cylinder head could crack and allow coolant to enter the combustion camber. This condition would cause white smoke to blow out the exhaust.
White smoke usually indicates steam. I don't think a bad intake manifold gasket would cause it, but a bad or blown head gasket certainly would. More than likely it is a bad head gasket or a cracked head. White smoke means you are getting anifreeze in your cumbustion chamber (cylinder) and when it fires it is burning the moisture creating white smoke.
Bad spark plugs and leads can commonly make the engine feel like its 'hesitating' or skipping a beat, often worsening in the higher rev range. However it is not the cause of white smoke. White smoke is typically associated with coolant getting into the combustion chamber. The most common cause of this is a cracked head gasket, which you will need to replace in order to rectify the white smoke.
Can a bad oxygen sensor cause overheating and white white smoke from the exhaust on a 1992 Honda civic?
I changed the thermostat and put a new radiator cap on a 1996 Geo Tracker. Now there is white smoke coming out the exhaust. Could it be the fuel pressure regulator is bad?
Check for water in your oil, if so, this is a sign of bad head gasket. White smoke from the exhaust and loss of coolant with no apparent leak are all signs of a blown head gasket. You can also remove the thermostat (it is much cheaper to replace and easier to troubleshoot as well). If the temperature of the vehicle lowers, your thermostat was the problem.
Typically, white smoke after sitting over night is just steam from condensation or moisture in the air. However, thick white smoke while at operating temp is an indication that you are burning anti-freeze. You may have a blown head gasket if this is the case. Over filling oil can cause a white/blue smoke as well.
1992 Acura Legend LS coupe is overheating but the heator is not blowing hot there is a little smoke out the tailpipe only when the temperature has gone beyond the normal range?
Most likely your thermostat has gone bad. Cheap and easy repair. If its white smoke coming out the pipe it may be a head gasket,,the smoke is acutally steam vaporating out the chamber thru the tailpipe...if it starts a second then stops you may have just gotten away from a going bad engine and itsw the thermostat..have it checked..
Bad thermostat, air bubbles in the line, cooling fan relays not working, or the worst, bad head gasket. You can tell if it's a bad head gasket by white smoke coming out of the tailpipe, brown, sand-like gunk in the old radiator (and possibly new one) and oil mixing with your coolant. Does your heater still work? If not, there's likely a bad thermostat or air bubbles in the line. Make sure you reconnected all…
Can a bad thermostat cause your battery to go dead and ac blow hot air And what other negative effects can a bad thermostat have on your vehicle?
I've actually heard a bad thermostat can cause the evaporator core to malfunction.I've also heard of some a/c compressors will shut off if the engine temp gets to high which could be a thermostat issue. No, the thermostat has no effect on the battery or on the A/C. A thermostat either works correctly or it will stick open or stick closed. Sticking open will cause the engine to never reach full operating temperature, and as…
What could cause a 1992 mercury grand marquis to overheat after installing a new water pump and thermostat?
When you first crank up your car it puts out white smoke for a few min then stopsi have a 1999 olds alero its also losing water nothing in reservore and no heat help?
if the radiator is getting hot enough, yes the white steam is most definitly from the antifreeze. anti freeze gives off a slightly sweet smelling white smoke when burned. You will find the same or similar smoke from your tail pipe if you have a bad headgasket. bad head gaskets can allow coolant into the firing chamber and end up in your exaust.
