Flushed with success
 

cold passenger side heating has been resolved with a flushing additive (Wynns), running the car for a couple of days, then reverse flushing the matrix. Better than taking the matrix out!!

well done that man

Hello, I have the same problem on my 75 2.5 v6.
I will try to purge my cooling circuit.
Can you explain to me how you proceeded and what is this product?
Thank you very much.

Flushed with success
 

the product available at any car accessory shop is a radiator and matrix flush and cost about £8 i think. Simply add to the cooling system, after having let some coolant out, then drive for a few miles in low gear so it circulates well. When it's cooled off disconnect the inlet and outlet pipes to the matrix and use a hospipe to reverse flush the system. I was lucky that this cleared out the gunge that was part blocking the matrix. I gather that doesn't always work unfortunately and the cure then might be a new matrix.

Thanks you, i 'll try this. :}

The product that I used years ago was Holts speedflush. It could be added to the cooling system (after removing enough coolant for it to displace). The instructions then said to run it up to temperature several times, then flush the system with water before draining again and refilling with coolant mixture. As various products were either acidic, or in some cases, alkaline (not good with aluminium!) it was important to flush out well, or risk further damage by the product! Check the instructions on your product carefully to avoid damage to alloy parts or seals.;)

Last year, I tried putting two dishwasher tablets into the system. I drove with it for about a week and then I changed the fluid. Everything is fine and everywhere is warm.
