Just taken the car out to get to the merc at the top of the drive and noticed that the passenger side footwell is completeley drenched! Reached around and the entire dash behind the glove box is dripping wet...all the windows steam up if i have the car on for even 30 secs...wtf?!?!?!?!

Thats your heater matrix under the dash, there was a rencent thread on it, could that be the cause

??

Dono...can a duff heater matrix cause the car to pressurize overheat or is this a new problem?!!!?

Sorry buddy no idea !!!! Would have thought it wouldn\'t help, but the over pressurize could have popped a pipe on it !

Yep, Your effectivly removing coolant from the system and replacing it with air which does not cool as Effectivly. Water boils at a higher temp when its in a Closed space but if you vent it then heat up it will boil, Its the steam that you can feel over pressurize the Pipes

Try conecting the two Matrix lines to each other where they go through the Bulkhead (so you bypass the Matrix) this will tell you for sure if its your Problem. Just make sure you blead it up well. Also you won\'t have warm air in the Car so this is a short turm fix to see if its defo your Problem.

Unfortunatly a heater matrix is not a Nice job to do (you have to remove the dash)

What should i use to connect the two lines? Is there a pic of which ones i need to conect to each other?

I\'d just join them together with a peice of metal pipe and some jubilee clips.

If i remember correctly (this is along time ago so don\'t hold me to it) but i think you can conect the Bottom pipe to the Steel pipe the Top one is conected to (if you get where i\'m coming from)

I Don\'t remember using any extra Pipe or Clips at the time it was a "at the side of the road" fix.

Rixio · September 10, 2006, 01:59:13 PM

Will go out and try that now! Lets hope it works...

Just make sure you bleed it well.

Rixio · September 10, 2006, 02:14:53 PM

You mean bleed the coolant system or the heater system? If its the heater system how do i bleed it?

Grizzly · September 10, 2006, 02:45:07 PM

No i mean once you take the Matrix out of the Equation you\'ll need to bleed it up well as it will have lots of air in the system.

I\'d just stick some tape over the Matrix Pipes so you don\'t get the Crap of the road in them.
