is there a heating diagram available somewhere? when i have the engine bay open tomorrow ill check to see if any of the pipes are in the wrong places and check to see if the return is blocked, ive got some electricians cable hook things in the shed so ill stick those tgrough and see if theres any crud.

as suggested i have finally found that the pipes have been removed for some reason, ill try to reconnect once i figure out the other issues.
thanks all

the pipes for the rear matrix have been removed? matbe yhey were blocked, it was suggested to me that if my pipes were blocked, it would be easier to use rubber radiator hose and just replace the full pupe. today i have found they are not blocked, and that there was actually no thermostat in the engine, nowni need to figurenout why :/

Pipes removed due to corrosion, so would flush the system with rad flush AND drain the block after say 100 miles or so. Clearly van has not been looked after

thanks all, i have been flushing the system then running then flushing etc, i think the front matrix may be blocked up as it only gets luke warm,next job is to try and clear it

need to flush with hosepipe to stand a chance of dislodging I reckon some has tried so mechanic in a bottle!!!!

dave, to check if the matrix are blocked i dont the following,

remove the return pipe (left pipe) from the filler tube
jam a piece of spare hose in the end (enough so it can reach the floor)
remove the flow pipe from the firewall end
warm up my filling hose and jam it over the flow inlet
hold it in place and get someone to turn on the tap

the matrix filled up and i was able to see the water flowing from the return pipe showing that the matrix was not blocked.

for the rear matrix, seeing as i was installing a new thermostat, i took off the flow pipe from the thermostat housing and jammed a hose on the return pipe tonpush water through and check if the pipes were blocked, they flowed fine but i still have no rear heating so im stumped for now on that one untill i have some more free time to do further checks
