- E300 td est 1988 avantgarde, astra est 1.3 td 6 speed 2006.
Hi I have a e300 td est auto 1998 and have had a new belt water pump idler and gearbox oil change all genuine merc. Yet while towing my caravan the temp goes from normal 80 or under to 80-100 on guage then a big long hill and she rises even more and starts to smell. If I put on the heaters this helps .when over the hill heaters off and she is ok again still higher than when not towing. any clues please. my merc indie could not fault the car when i had the oumo etc done. ps the pump etc was done for peace of mind it had no leaks or faults. milage is now 126,000.
