my 87 t2 has been over heating and i cant figure out why. i put a new radiator in it because it was leaking and i put a new thermostat in also. and when i first start the car it has a hard time getting started and when it does it smokes white smoke for a minute and sound like it is missing a rotor and then it warms up it sounds fine and stops smoking and all the power is still there . so any help would be appretiated.

Do you have to keep puting water in the car once a week or more.



Once you come to a complete stop and get out your car do you see water coming out you overflow tank ?



When it smoking go behind the tale pipe and take a wif of the smoke . what does it smell like?

you need to get a custom shroud to fit your fan. if engine continues to smoke, u need a rebuild.

smoking white + overheating is most likly your coolant seals are shot.



which requires a compleate engine rebuild or a new engine to fix.....

the smoke smells like gas and yes it spills coolant out of the overflow tank

Yea it sounds like class seal break age due to hundreds of reason.



Next step coolant system pressure testing to make sure.

White smoke that smell like gas could be a bad pre-cat.
