Default Not that bad

I've done this job three or four times now, and it really isn't too difficult.

They tend to leak into the left hand passenger footwell.

You take it out on the passenger side.

I clamped the engine bay hoses without any issues, but I do have a proper hose clamp.

Remove the carpets as far as you can. Taking the matrix out results in spillage, which otherwise takes ages to dry out.

Get new Volvo O-rings.

Get a branded matrix. Cheaper ones have fewer channels and don't heat the passenger compartment so well. The ones I've had from PartsforVolvo were fine. The Eurocarparts one was rubbish.

Fit a new thermostat whilst you're at it.

Make sure you put back the little drain hose. You'll see what I mean when you get there!

Hope that helps.
