Bout to hit 300k tomorrow on my 2012 and I’ll I’ve ever replaced is the radiator and a transmission sensor. All the pulleys are oem
2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.
E36 on factory, untouched cooling system replaced earlier this year. Date stamps on the radiator, hoses, thermostat housing all indicated they were never replaced.
No, the best radiator is Toyota OEM it can last over 25 years.
It happened to me once at a night time. I just pulled over, stopped the engine and started again after several minutes and everything was OK.
Edit: After reading other's comments, I realized that mine also related to coolant system. Some time after this incident I replaced radiator because of a coolant leak. May be this warning is related to that.
Shortly after owning it I had to replace radiator, Dan shroud. Then my power steering rack and CV died. Just recently my master break cylinder just died
My first non warranty repair on my B58 540 was a $3k radiator replacement. That was at about 60k miles.
I got done years ago for a polished aluminium radiator in a 1985 4th gen Celica.
My first new car was an ‘82 Toyota Celica. I put 3 radiators on that car within 10 years. The OEM radiator had a copper core and plastic tanks, held onto the core with a crimped clamp all around. I don’t think that they paid much attention to expansion rates and coefficients of expansion of different materials when they designed these, and the seals would eventually give out and begin leaking.
You need to replace that. Bmws run hot. Only fix
