She now has a warm cabin
Firstly though a big thank you to DickieG who came up to help replace the heater box at very short notice today. Thanks Richard, you really are a star
We worked from dawn to dusk on it today with just a short break for me to visit the dentist for Root Canal part II. That's all done now and X-rays confirm it's been a success..
Replacing a heater box is a step on from a matrix replacement but a biggish step. And it's is essential to have two people on it. At one point we wondered if it was possible to even do it without removing the whole heater box but in the end it was just possible
We discovered on our way that the last person to replace the matrix did it with a crowbar, pickaxe and a sledgehammer
One dash bolt pillar was broken, one of the ones that pass through the bulkhead, and there were several cracks in the dash itself along with plenty of evidence of gorilla attacks and assorted bodgery
On easing the old heater box out we were staggered when it came out almost in two. It was split in half. No wonder it was not working very well - most of the air was escaping from the split..
But why was the box split. We found that when the old matrix came out. It was an odd one we've never seen before - black and looking more like a coolant radiator than a matrix and much heavier than the standard one. Basically, due to the design of the bottom end it fouled on the base of the box and the gorilla fitting it gave it a big shove and tightened the securing screws down on it and promptly split the box in half
Richard noted that the date on the matrix was different to that on the pipe extensions. Our guess is that the matrix was never designed for the Xantia and was faked up to fit by using the pipe extensions from the old matrix. It had just started to show signs of leaking too...
Goodness only knows what it was designed for
Maybe a CX perhaps or even a BX?
All's well that ends well and Rattiva is certainly warmer than she was..
As a bonus, we replaced all the blown instrument bulbs. I can see how fast I'm going now
Just a few jobs to finish off and all is done.
This is a picture of the old and new matrixes and split heater box. The odd matrix is the one on the right...
Again, many thanks for today Richard
