Problem solved!!!! after much trying and 2 different types of Y piece and 2 attempts to plumb it in I've finally got it right
i bought a genuine ford Y piece http://i120.photobucket.com/albums/o192/jindal/2012%20quantum/IMG_20130128_070233_zpse2be132d.jpg fitted it in, all went quite neat actually http://i120.photobucket.com/albums/o192/jindal/2012%20quantum/IMG_20130130_075742_zpsaa5c7754.jpg eventually i fitted it so that the long straight leg links the bottom heater matrix outlet to the water pump inlet to provide a strong draw of fluid through the matrix (the Haynes manual shows the pump to the top matrix hose but my figuring is that once the fluid cools and condenses the cooler fluid will sink lower and be drawn off by the water pump) the inlet manifold bottom union goes to the side leg of the Y since it (in theory) gets a bit more push from the pump through the block and out the union under the manifold so diverting the flow to the side leg of the Y should be sufficient. then the union from the stat goes to the top matrix inlet to provide plenty of hot water direct from the block to the heater, and the results are that for the first time since i rebuilt the car 3 years ago i have a fully functioning heater, there are now no air locks since the transparent 90 deg elbows i mentioned earlier on as having no blue coloring to them from the coolant now have a strong blue colour to them http://i120.photobucket.com/albums/o192/jindal/2012%20quantum/IMG_20130130_181737_zps4b39812c.jpg so happy days and thanks for the input On Sunday, November 18, 2012 9:45:36 AM UTC, jin wrote: > > having trouble finding the answer to this, and ive asked in 4 places > so far > > could you guys take a look at your Y pieces in the heater matrix > circuit and tell me which way they go please? > > in my wisdom when i replaced the matrix last year i used a T piece as > it looked better and the pipes fell in the right position, but i only > get warmth through the matrix when the stat is closed (presumable > because there is more pressure) but when the engine warms up it all > go's cold inside, presumable because I've put the T piece with the > straight edge going across the manifold and the single leg going to > the union into the manifold, i guess that the Y piece single leg goes > to the manifold and the 2 closer legs go to the 16mm heater hosed? > > any info much appreciated, a picture even more so. > > -- -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
