Give us the year, make and engine info for more suggestions.
There are many possibilities. It could be caused by timing issues, vacuum leaks, faulty fans and a bad water pump.
My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.
yes, leaking coolant is what happens before the pump totally dies, then you have overheating and possible engine damage soon after the leaking.
Happened to me in France, you can still move the van but beware of overheating...
No ,more damage will occur including overheating
Yes, but you run the risk of the engine overheating when sitting still.
the head may need to be skimmed or a new head to be fitted
Is your fan coming on?
i don,t know but mine is the same it takes a quart after 600 km. i,m sending it back to where i got it rebuilt
Could be the head gasket. Very common problem with this engine and model year Windstar.
White smoke from the exhaust indicates you have a blown head gasket or cracked head. Stop driving the car until this is repaired or you will do serious damage to the engine.
i have replace the thermostat, checked the fans,filled with water and it is still overheating. Very often, the waterpump leaks and stops working only years after it was last replaced. Coolant is probably not flowing from the engine to the radiator to be cooled.
Overheating often warps the head. If the heat was high enough then the engine block could be ruined as well. Check the compression to see if it is still in the right range, this will help determine the amount of damage.
