I've got the standard unit in my 1992 cooper and its leaking.... thing is I don't think the matrix itself is leaking I think its the coolant pipe into the bottom of the matrix. Is this common? Easiest solution? Would draining the system and chopping half an inch out the pipe solve the problem? My thinking is the pipe may have gone a bit baggy where its attached to the matrix (the jubilee clip thing) holding it on is tight as hell, so its not the clip thats at fault.

Thats the first thing to try , if that dont cure it then it is the matrix.

I sure hope it doesn't turn out to be the matrix..... anyone know the best(i.e. cheapeast) place for a replacement matrix?

Another thought..... rather than hacking the end of the coolant pipe to the heater matrix, would using some plumber tape on the heater output be a worthy exercise?

I mean it really is just a drip, i remember fixing my house radiator for exactly the same thing a couple of years back.... obviously modern gas central heating is pretty high pressure so the tape is up to that, its gotta be up to a little metal water pumps feeble output surely?

Well it is the matrix....stripped it down and the bottom loop pipe has 4 holes in it.... tried my hand at brazing them, but no luck still a leak (albeit a smaller one).

So off I go to buy a new matrix.

My heater matrix is also leaking in my Pickup, I was going to remove the whole heater unit and not even both with a heater at all! Assume you can get a bottom hose with no heater take off and something to plug the clyinder hear tap.

I think by the time you bought all the replacement pipes and fitted them it would be less work/hassle buying a new matrix and fitting that. Only my thought, I quite like the idea of warm air in the cabin when its baltic outside... Even though you get the disadvantage of warm air even when you want cold in a mini haha.
