any one replaced heater matrix help and advice please

lol.......its an all day event with or without taking off the dash...search for the guide on how to...its been posted before...also IIRC you can buy a nissan primera matrix cheaper but the same

It takes about 10 hours if you'vr never done it before. It isn't technically difficult just a lot to remove to get to the Matrix. I advise you remove the full dash as it will take longer fiddling around with just all the bottom pannels off.

 

I also advise that you get new rubber (or silicon replacements) heater matrix pipes that come from back of engine to the heater matrix pipes that poke through bulkhead.

gonna start doing mine this weekend, been dredding it for ages!

I did mine in 7 hours first time. Then I had to take it out again when I broke my car, lol

got clutch booster to do at the same time

 

not so bad but i have a new headunit to go in at the same time and will probably have to rewire all my gauges again!

Just to let you know that the next time you do it it will only take you about 7 hours :smash: :slap: :rofl: :rofl:

 

PS I had the aircon assembly out as I was also fitting a new EFI ECU harness

I need to do mine too, apparently you can do it by taking the clutch pedal off, its on a slide so slides out towards the clutch, no real benefit from removing the dash, but dont quote me ;)

1)You Have to remove all the lower panels, The framework that supports them, the cross support bar the centre box and gear shift suround, the clocks, the sreering wheel.

 

1b)Then if you want to go clutch peddle method you have to be Quassy Modo or Origarmy to get the clutch peddle box off. Which means rummaging down the back of the engine. Believe me you still have restricted access .

 

1a)Dash out method means as 1) but just removing the dash and upper air ducts. But you have free easy access to everything and you can see which wires need unplugging which you can't the other way and end up having to cut wires etc.

 

+ which ever way you do it all the lower ductings need to come of so you can slide the matrix assembley out of the end of the aircon assembley.

 

Last thing to know. When you reassemble make sure you reconnect all the sensors and fit in correct places in the ducting or you'll have no control over the air temp you sellect.

Mark, i have had my air con removed so can i also remove the air con assembly from the dash, will it go back together without it?

No you have to leave it in place because your Heater fan for the blowers is at the the bottom of a vortex type intake that draws air from out side or inside the car and blows it over the heater an aircon martix to exchange the heat or cold. The Aircon matrix is between the fan housing and the heater matrix. I suppose you could remove the matrix but you'd have to seal the pipe holes through the bulk head and reinstall the Aircon matrix housing. Or just leave it in case you change your mind.

ok ta

You need a "greg" !, Seen him replace them at SWZ in a couple of hours, without dashboard removed.

I took the air con matrix out cause it does weigh a bit!

 

Tape over the gap on the housing and popped her back in!
