i have an 1997 c250 td, it has just started to overheat big time,
i am a taxi driver and had been driving for 4 hours and it started to loose power, when i looked at the gauge it was up at the red, i stopped for a while and then drove it home but it kept rising into the red, i am now fearful to drive it, as as soon as it heats up it goes up to red , does any one have any idea what would be causing this, and do you think i have done any damage by driving it home. there are 120,000 miles on car
