My '91 525i with 250,000+km overheated last night just before I got home. I managed to get in my driveway luckily.
I'm not much of a gear head but I will ask the obvious: What could have caused the sudden rise in temperature?
Some history of my car:
- noticed that I was losing coolant for the past few months. Had to top up a litre or so every 500km. Noticed a month ago that the upper rad hose was leaking due to a crack. Coolant would drip on one of the pulleys after I shut off the car. Replaced it but was still losing coolant. No leaks after replacing the upper rad hose.
- I suspect I am burning coolant and was told that was bad for the engine. Was asked to check the exhaust colour and smell. Seemed ok to me.
Any help would be appreciated. Thanks in advance.
