Bloody O'rings

Correctly fitted and seated O ring rings dont need any pressure or squash to seal. If yours are leaking they are not seating right. Over torquing the screw will just crack the casing leading to the mother of all repairs - the matrix removal....

And you dont want to be doing that I can tell you:(
 
Also seen one of the alloy pipes with a pin hole in it right next to the 8 shaped clamp that holds the pipes into the matrix.....
 
Or of course you could get over zelous with a pad saw when cutting the air duct to get access to said O rings.............

I remember seeing this photo before doing mine and was extra careful! I did the screw on the clamp up hand tight and certainly made a point of not applying any excess force.
 
Can I just say that I found the whole job of replacing my heater matrix O'rings not that big a deal abit fiddly but really easy but as I started I found it had been done before but had to enlarge the hole in the panel a little,it did drip a tad but my screwdriver did slip cos it was worn so went and got a newone and one more turn and it fine no drips in nearly 2 weeks, one question though can the leaky seals pull air in cos they didnt leak much beforw I started and I was getting overheats'but since doinh them no temperature rises at all rock solid even im heavy traffic jams, guna sort mh lpg problem next

They can draw air in but also there is a loss of pressure and pressure is what stops the water boiling.
 
Well its one job crossed of my list, I just bought walnut trims for the interior cos it doesn't have all of them fitted, ,why would u have some and not all unless some one replaced them crappy plastic ones, , cheers
