306 D Turbo heater problems - gazsa401 - 09-10-2016 Looking for some advice on heating not getting very warm I've recently put 2 lots of Wynns coolant flush fluid in and cleaned out the cooling system But for some reason I'm only getting luke warm air coming blowing through Any ideas thanks RE: 306 D Turbo heater problems - Mattcheese31 - 09-10-2016 Losing any coolant? Bled properly? 306 D Turbo heater problems - gazsa401 - 10-10-2016 (09-10-2016, 08:00 PM)Mattcheese31 Wrote: Losing any coolant? Bled properly?I've ran it and bled it until fresh coolant has come through Would you recommend having both bleed screws open at the same time thanks again RE: 306 D Turbo heater problems - Mattcheese31 - 10-10-2016 you need to create a header tank ie pop bottle in the radiator to get the coolant all the way up to the matrix, or blow through the overflow pipe with your hand over the rad cap hole,think there's a guide on here RE: 306 D Turbo heater problems - carlukepeugeot - 10-10-2016 Yeah, as above, the filler neck of the the radiator is lower than the highest point in the system (ie the heater matrix). So in order to get coolant all the way to the matrix and push all the air out, you are supposed to get / make a header tank. I usually use an upturned 1L coolant bottle. Cut the bottom off, and use O rings to make sure that you get a water tight seal between the bottle and the filler neck when it is inserted. You also need to plug the overflow hole on the side of the filler neck otherwise it will all pi5h out!. You basically want to fill the system, working your way from the bottom bleed screw up to the one at the matrix level - ie open the one on the rad top until coolant flows out clear of air, then close. Now repeat with the one on the hose from the heated fuel filter. Fill your makeshift header tank to whatever level is required to achieve this. By the time you get to the heater matrix one, you will need to fill the header tank quite a bit. Again, once coolant runs clear of air, close it off. Now run the car and let it heat up until the cooling fans kick in (keep the header tank fairly full). The engine should take in the coolant in the header tank. Lastly let the car cool. Hopefully all the coolant went in from the header, which you can then remove and just top up the level if required. Remember, it isn't important whether or not you have the hot / cold valve set to hot or cold, as on the 306 the valve adjusts the amount of hot air which is delivered rather than the amount of coolant flow through the matrix - on the 306 the matrix always has maximum coolant flow, one of the reasons it is so important to do all this - the matrix forms part of the required coolant volume for effective cooling of the engine.

I've successfully wrapped masking tape around the opening of the bottle until it becomes a snug fit in the radiator filler neck. RE: 306 D Turbo heater problems - vincent1 - 11-10-2016 ive also used insulation tape around the bottle cap threads which seems too work well i also had this problem with luke warm heating i fully flushed the cooling system changed the stat bleed the system numerous times still cool in the end changed the matrix and it was like a new car heating really good never had a issue after.I guess some of the matrix tubes was partily blocked alowing only a little hot water too flow through the matrix. RE: 306 D Turbo heater problems - r3k1355 - 11-10-2016 Yea it's a total lady garden to bleed it properly, and if you don't air will get trapped in the system and can cause you issues later. 306 D Turbo heater problems - gazsa401 - 11-10-2016 (11-10-2016, 08:37 AM)vincent1 Wrote: ive also used insulation tape around the bottle cap threads which seems too work well i also had this problem with luke warm heating i fully flushed the cooling system changed the stat bleed the system numerous times still cool in the end changed the matrix and it was like a new car heating really good never had a issue after.I guess some of the matrix tubes was partily blocked alowing only a little hot water too flow through the matrix.Is the matrix easy to change thanks RE: 306 D Turbo heater problems - Mattcheese31 - 11-10-2016 (11-10-2016, 04:59 PM)gazsa401 Wrote:(11-10-2016, 08:37 AM)vincent1 Wrote: ive also used insulation tape around the bottle cap threads which seems too work well i also had this problem with luke warm heating i fully flushed the cooling system changed the stat bleed the system numerous times still cool in the end changed the matrix and it was like a new car heating really good never had a issue after.I guess some of the matrix tubes was partily blocked alowing only a little hot water too flow through the matrix.Is the matrix easy to change thanks i wouldn't say easy, took me about a day but i'm a slow worker lol, people that know what they're doing quote 3-4 hours RE: 306 D Turbo heater problems - vincent1 - 11-10-2016 yes took me about 6 ish hours there is a guide on the internet to do the swap hopefully someone will post a link too it for you Edit!! heres one i guide i found http://www.306gti6.com/forum/showthread.php?id=78999&page=1 RE: 306 D Turbo heater problems - The Phil Billy - 07-11-2016 im going to try this tomorrow! ive been having a night mare to try and get it to bleed through the matrix properly i even tried having the front end up the slope into the workshop thought it might oh helped but was still a bugger RE: 306 D Turbo heater problems - ADV_93 - 12-12-2016 Is your heater tap opening all the way?

Any further advice would be appreciated thanks RE: 306 D Turbo heater problems - Mattcheese31 - 13-12-2016 one bleed screw screw at a time, radiator, thermostat then heater matrix, get the water level above the highest bleed point and make sure the thermostat has opened, it swallows about another litre when it does RE: 306 D Turbo heater problems - vincent1 - 13-12-2016 Sorry i missed this bit where you said this Just want to add something more for advice really I changed my radiator last year plus fitted a new cam belt water pump and thermostat My heater worked great before I changed all those things but since then I just can't get the heater to blow hot (just luke warm) So that's why I'm trying the heater resistor or would you still recommend the matrix as well thanks so it does still sound like a airlock somewhere all you can do is just keep trying to bleed it whats the temperature gauge go up to in the car? was it the correct temp new thermostat you fitted? 306 D Turbo heater problems - gazsa401 - 13-12-2016 (13-12-2016, 05:06 PM)vincent1 Wrote: Soory i missed this bit where you said thisI forgot about the radiator bleed screw doh!!!! I also lost the bleed screw near the fuel pump it fell into the bell housing (school boy error) it's took me ages to buy a replacement screw The temperature gauge went up to over 90 then the fan kicked in and it settled back down to running temperature I'll try again tomorrow to sort it and let you know Again thanks for your help and others on here |
