Try any Mazda dealer & yes it will need to be bled, any work on the coolant system needs to be bled afterwards.

Thats exactly right if its for a 2.5 diesel I have my new hose in front of me now I have not fitted it yet!! AVA had one last week too ask for Andy see if they still have it.randombit wrote:been havin trouble getting hold of this hose now. but have been given the mazda part no. s09g61214.
Hi Steve. Ta for the kind thoughts. LCA didn't pick up the problem because the leak did not drop the header tank level far enough to trip it, when the Bongo was last on the road. It's all "dripped away" while I was in hospital - ouch, a bit near the mark that!bigdaddycain wrote:Sorry to hear you aren't 100% Dave...

Bad news on the leak mate... Did you determine why the LCA didn't pick up on the empty header tank? This just goes to show that a visual inspection of the hoses is what's required...I only rely on my LCA to pick up an overnight coolant loss really, some are over complacent about not checking just because an LCA is fitted.![]()

Looks like a rear heater matrix problem.Ron Miel wrote:Wrong! Managed a full limbo under this afternoon, and:Ron Miel wrote:>

1.) The leak is at 61-211A, here - http://www.lushprojects.com/bongopartsm ... mgno=.html
2.) It's not a pinhole leak where the coolant is dripping. Coolant is running down from a hose-end leak, where it connects up into the rear heater matrix.
Tried shifting/tightening the hose clip but that didn't do the trick. Coolant is still messily running out and it will need a full drain down now to be able to see exactly what the problem is, and whether or not it could be repaired with say just a new clip, Rescue Tape, or whatever. So, instead will order new hose and clips first, then drain off, fit new items, flush, refill, bleed, etc.
Not the best game with two new bionic knees and a pared down prostate!
