Mikey S 29 1 Cars Posted November 9, 2008 yes mate, undo it with the engine not running and wait for the air to bleed out. it maybe neccesary to blow into the header tank to force the air out. once the coolant comes out uniterupted, put the cap back on and try it.

Guest sam-kearney Posted November 9, 2008 mmm frustration now,, couldn't wait till the morning, so i went out and gave that a try there, yes i got a bit of air and then a load of coolant on the ground but still not much heat!!!! have i bigger fish to fry--or freeze-- now, would it be my interior fan it kinda whistles as its blowing not alot of power in that either ie: a sheet of paper won't get blown away from the window demister,, wasn't really a problem in the summer but its is now as this is my one and only car!!! i will be gratefull if anyone can give me a few pointers Share this post Link to post Share on other sites
grandos 16 Posted November 9, 2008 Did you top up the coolant while you had the bleed screw open? Make sure you keep checking the level. The way I bleed the system (may not be the correct way) when filling, is to keep topping the coolant reservior up till it gets to the MAX line. Then open the bleed screw at the back (heater matrix) then the bleed screw near the distributor. All the while macking sure the level is allways at max. Give the top rad hose a couple of squeezes to help move things along. I then close all the srews and start the engine. With the coolant bottle cap off switch you blower speed to max, temp to max and let idle for a few minutes. At this point I open the bleed srews again (just a bit) to ensure collant flows out (not air)then close them. If you get no coolant keep them open till you do. Keep checking the level of the reservior. This normally does the trick and then close the coolant bottle cap and check the engine fan cuts in and out. (at operating temp), one working perfectly cooling system Share this post Link to post Share on other sites

Guest sam-kearney Posted November 10, 2008 iv'e tried this now it is a couple degrees warmer now alright!!! nothing too sweat over tho =^( Share this post Link to post Share on other sites
mhyphenl 10 1 Cars Posted November 10, 2008 iv'e tried this now it is a couple degrees warmer now alright!!! nothing too sweat over tho =^( Just had the same problem with mine! There was no warmth at all from the blower. Firstly, under the drivers side of the centre console those two pipes come in from the bulkhead and into the heater. See if they're both getting hot, only one of mine was getting vaguely hot. Because the heater pipes are in the 'closed' loop, (ie thermostat closed!) Water should be circulating all the time. On mine I resorted to taking the pipes off the engine side going into the bulkhead and flushing water through with a hosepipe, I got completely covered in rusty gunk! Sorted it though.

Tom Fenton 1,542 Posted November 10, 2008 As above, disconnect the pipes into the matrix and give it a good flush out to see if you can shift any crap, and then bleed it again. Also is the thermostat working? The car should come up to temp reasonably quickly from a cold start. My 205 heater gets really warm so when working properly you should get enough heat out.

Guest sam-kearney Posted November 10, 2008 ohh yeah must give this a go!!! i'll get the garden hose out wednesday!!! how would i know if the thermostat isn't working!!! after a long blast when i get home and lock up the car the radiator fan still whizzes on for maybe a minute or two, is this normal procedure?? my last cars didn't do this? btw thanks for the help!!!

chris1986 1 Posted November 10, 2008 i just put a new heater matrix in and i'm warm again, feels much warmer than with the old one. worth flushing though and i always bleed these up with the engine not running and top up till water comes out of both holes, then run for a while and check level.

chris-stdt 0 Posted December 8, 2008 You shouldnt need a new one unless its leaking ,i had to flush mine out as i put some of that powder to stop radiator leaks in mine as a stop gap before fitting a new rad Completly blocked my heater matrix and all i did was take off hoses as described and flush matrix both ways a few times ,put pipes back on and i had heat !!!
