Need Help Asap!!!
I have an 98 528i BMW and yesterday i was in going threw the drive threw getting food and then i notice my car started to over heat. So i parked it for like 5 mins started it back up and it was normal then let it sit there for a min or 2 then it started to over heat again. So i turned it off let it sit for a little longer started it and it was back to normal so i was driving home and about 3 mins into driving it started to over heat alittle but then went back down. So pretty much when i drive it over heats then it'll cool down alittle then it'll over heat again its weird. I dont know anything about these kind of cars and i just got it last week. I was thinking it could be the thermostat sticking but the dude i got it from got a brand new thermostat, water pump, and clutch fan put in it the day i got it. And i also noticed when i start it up now theres lie ka dark gray of smoke coming from the exhuast. Any ideas ?!?!
Let me know THANK YOU!!!
