Hi all,
I need to replace the heater matrix on my BMW 530I MSport 2006. But I refuse to pay 700 to 800 pound for a days work. I know its complicated but still a days work. I work 12 hours and mostly on my feet and I make a 150 a day. I may be able to do it myself but not when it's cold like now. Also after watching a video on how to do it, I might be able to take everything off but putting back together will be tricky. For someone who has done this before, it will be a easy job. Is anyone willing or knows anyone who has done this work before and will not charge a extortion rate.

A bit about the car, looks lovely just as I had seen it advised. Didn't check the heating. Realised a few days later. I have changed the electric water pump and thermostat,along with a radiator. Who ever had the car before, put kseal to mask a radiator leak. But still no warm air, the specialist garage came to the conclusion matrix blocked. They did say they tried flushing by sticking a hose pipe up there. So not sure if they tried hard enough to dislodge anything. I have spent alot by doing the above along with a major service. Anyone have ideas how I could attempt to flush the system myself, anything I can use. Or a place which can change the matrix and not charge a arm and a leg. Thanks

I'd remove the pipes and flush myself to make sure it's blocked before removing and replacing. Do a reverse flush, it usually works better if there's something to flush. Having said that, I don't have the same car so no idea how easy it would be to do .. though I've done it many times on landrovers .. ;)

Thanks. I will do that but was a bit worried that I might damage the core and it might start leaking. Anyone has any ideas what might work to dissolve the kseal, nothing harsh.

Problem is it's doubtful you'll remove the k-seal it's that good ... I've used it for curing head gaskets on crap cars and it works brilliantly .. for a few weeks at least .. ;)

Dunno how you know it's K-seal, but if someone's used K-seal in a rad/heater matrix then the core is 99% junk anyway and a new matrix is needed, so why not just flush it and try, you never know if it's K-sealed or just crap in it ... A new matrix might be reasonable cost, my new full radiator and Aircon condenser cost ~ £220 see thread MY BUST RADIATOR

Do not assume that your heater matrix blocked! Flush it through an just run with it! If it does not flush then you have a problem?

I flushed it back and fourth and used holts speed flush. It worked mate, I have heat finally. I even replaced the oil filter gasket along with the cooler one. I will put a post up on here next week and tell you guys how I did it including the hurdles I had and there was a few. Thanks
