Craig, The only time I have ever had a leak around the otterstat was when the pipe was corroded and the seal wouldn't 't seal. A little silicone could helped, but sometimes the pipe may have to be replaced. As far as the bleeding of the air, That can be done at the bleeder on top of the water pump with about 99% total air removal. What's left on the top of the radiator is insignificant and wouldn't keep the otterstat from working properly. I'm in Texas when we run 90 to 100 degree a lot with no problem. This week we have been 95 to 100 and I just installed a Air Bleeder on a customers car and there was no further problem with temperature rise. If it turns out to be just a head gasket, that's not really a big problem, just be sure to mic the heads for warpage.

Ok my car passed the MOT and i have my UK reg and i got my car back from my father in laws garage (That saved me a bob or two). So it became obvious that i had a major leak from the otterstat...so i ordered the seal, clip and otterstat from dmch and took it to my local garage thinking it was a simple job...i would have done it myself but i wanted piece of mind. Anyway after replacing the parts it still leaks, exavtly the same from the otterstat as b4. The mechanic was recommend to me and said he tried everything. I drove it home (9 miles)from the garage and lost about 1/2 pint of coolant and it is now in my garage. Eberyone seems pretty confident it is not the Head Gasket (Please god not the head gasket(s))but after talking to the people who worked on it in my father in laws garage i think the local mechanic only bled the system from the bleed screw on the thermostat...should he also bleed it from the front of the car? How is that done? Could this be the culprit of the leaking seal? I have ordered an new seal stat and clip and the car is booked in or thursday. This is the only thing preventing me driving my D and discovering what next will go wrong:) any help appreciated craig DOC388 Vin 16723 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
