Heater Matrix Changing

[crazylex]

Anyone ever changed a Heater Matrix in an IS ?

Or maybe someone has a work shop manual (like then CD's on Ebay) they can fax me the relevant page over.

No its not leaking, but when I had a bump 18 months ago it started making this odd noise at 4k revs +.

Eventually a year after the bump Lexus leeds said their must be something thats trapped in the heater matrix. they clamped the hose and then the noise stopped. When its not clamped and you rev it with your head next to the matrix you can definately here it coming from there.

I got a new one from eBay for £30. (although I had at £11.50 - but I reckon I got bid up by the seller using an alias - thats another story though)

I undid the pipe clamps inside the car where they come through the bulk head and it seems like it might just slide out. But that just seems to easy.

I wondered if it is actually clamped in the houing.

it does slide out, but it needs to be uncovered by the dash and the heater box

Cheers Mat, better allocate a bit more time than I thought.
