4x4 how do u know if the heater matrix is knackered?
my cossie dont blow out hot air its blows in general but no how air?
theres obviously 2 pipes that go to bulkhead one is feed one is return?
should these bother be hot as each other or one hotter than other?

PassionFord Post Whore!!
I'd personally expect the one going in to be hotter than the one coming out of the matrix due to heat loss but not much different.
Have you tried bleeding the system? You could have an airlock.

Best way of bleeding any car I believe is to run it up to temp with the exansion cap off and the heater on hot.
I don't think there's a special way for a cossie
I normally squeeze the hoses but that might be just because I'm bored

you can but it would be best to take it out while its off
when i had to do mine i took the nipple out and ran the engine
nothing came out so there was a major airlock somewhere
i blew into the header tank and it started to flow again
also check to see if you have a thermostat
theres no gaske between the faces so you will need a tiny amount of sealant to put the cover back on

i think the therostats open at 82 degrees or thats when the fans kick in
i carnt remember and havnt got my manual here as my mates got it
but yes it should open before boiling point
what temp on the gauage do the fans kick in aswell
as if the stats late to open then the fans could kick ing and coll the water down before the water has chance to bve released form engine and flow round

with no stat the car will run cooler!
as the stat holds the water in the engine so when its at temp it opens and flows round the engine through rad etc to keep it cool
so the heaters will be cooler than what they are now
but if the stat is opening late the heaters should be very hot and and the car will be running hotter aswell
so now im lost
need to have a think about it now

but surelly if the stat dont get a chance to open cos the fan kicks in before it can open then there will be NO water going to the matrix which mean no warmth whatsoether! but if i take stat out then fair enough it wont be very warm but there will be water going in with a little heat?

the water will circulate around the heater etc before going into the rad after the stat opens.
sounds like its not being pumped round to me.
if the matrix was blocked, one pipe would get hot, the other remain cold.
i take it there is water in it lol???
touch the rad too, should be hot all over etc

ignore that last message i put water in without stat aqnd still dont make a difference. general engine temp is a bit lower.
the rad is warm all over so thats working.
the 2 pipes that go ino bulkhead which one is feed to matrix and which one is return?

when up to temp the rad should be hot, not warm!!
whats the inside of the header tank look like? is it all clean or is it dirty shitty water??
shounds like you need to give it a good flush though as in take the rad off and connect a hose pipe, and flush engine/heater matrix etc
but i still reckon the water pump might be fucked
