Hi Guys
I'm posting this on behalf of my dad who, if we're honest bought a bit of a pup. It's a Third Series one (made in about 98, am I right?). Since he has bought it, we've discovered all manner of sins and gradually repaired. The current problem, highlighted by the cold weather is the heater/blower. Only lukewarm heat comes through.
Having researched here, I've read that you can't really 'flush' a blocked heater matrix because blocked sections are bypassed under pressure - am I right?
We think it is blocked because amongst other things, the radiator had to be replaced and the old one was completely laced with gunk and rad-weld. Which we think has blocked the heater matrix as well? Am I along the right lines? Also the inlet to the heater is hot and the outlet is cold. The back blower (between the two front seats) seems to work okay.
As an aside, during the summer we also discovered the car had NO thermostat in the engine bay (filled with mastic plastic) - we think in an effort to botch an overheating problem.
So, does anyone concur that all this means we need a new heater matrix, how hard is it to refit (we've been told it's a 'weeks work' and includes removing the steering rack) and is it worth getting a breaking one or new one? How much are they?
Sorry for all the questions! Trying to help my dad...
I bought a '94 series 2 a year before and it hasn't skipped a beat....
