JustGav Posted January 23, 2008 Share Posted January 23, 2008 Disconnect the pipes and use your plumbing skills to connect them together so the water flows through these pipes and bypasses the matrix. This bit is still under debate I believe... It is possibly better to block off the two pipes rather than join them, due to the way the coolant flows through the head. I remember looking at the coolant flow diagram and it appears as though bypassing the matrix could result in coolant bypassing portions of the head. I would like either Ian C or CW to post their opinions on this. Quote Link to comment Share on other sites More sharing options...
madmunky Posted January 23, 2008 Share Posted January 23, 2008 Interesting would like to hear opinions on this too but the pipes just run to the in and out of the heater matrix so i dont see why cutting the matrix out would cause any problems?

Because the matrix will act as a restriction to the flow of coolant in the system, by joining the pipes it will provide an unrestricted flow through the bypass.

gavin.starr Posted January 23, 2008 Author Share Posted January 23, 2008 i see what you mean i might put a small crimp in the copper pipe then to act as a bit of a restrictor Quote Link to comment Share on other sites More sharing options...
merckx Posted January 23, 2008 Share Posted January 23, 2008 This bit is still under debate I believe. Coolant flow diagram I haven't studied the diagram much before, but I can see that blocking them off deffnately looks like the thing to do. Does the heater valve close to allow the engine to warm up quicker anyway or is it used for temperature control in the cabin? i see what you mean i might put a small crimp in the copper pipe then to act as a bit of a restrictor It wouldn't be easy to determine what restriction would mimic the matrix.

gavin.starr Posted January 23, 2008 Author Share Posted January 23, 2008 yea i figured that, but i thought that any restriction would surely be a bit better than totaly blocking them off as there would be no flow through the areas in which it would usually pass to meet up with the matrix Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 24, 2008 Share Posted January 24, 2008 Either block off both pipes or join them, no worries, the heater water valve does both when the matrix is in use. Quote Link to comment Share on other sites More sharing options...

JustGav Posted January 24, 2008 Share Posted January 24, 2008 Either block off both pipes or join them, no worries, the heater water valve does both when the matrix is in use. Hmmm, but it never allows full unrestricted flow. When the heater valve is closed it will be the same as the blocked off pipes. However when it is open, it goes through the matrix, this matrix does provide a restriction. I'm still unsure that a full unrestricted flow is without risks aka the joined up pipe option. (I'm trying to find that thread where we discussed it the last time, with regards blown HGs). Quote Link to comment Share on other sites More sharing options...
