burrowssj Posted June 12, 2011 Share Posted June 12, 2011 hello im kinda new here but I have been reading these forums for a while. I was wondering if someone could shed some light on the heating system in a 1600 crossflow. Basically I flushed the whole cooling system twice an used that repco flush. the water is now nice an clear but the heater still does not work. I assumed a leaking/blocked core so today I ripped it out an put the hose into it an abit more orange filth came out but it doesn't appear to be leaking at all :/ If anyone has a 1600 crossflow with the single throat carb could they describe where the heater hoses go? Il post the pics of how mine goes an hopefully someone can point me in the right direction of whats wrong with it. mine goes waterpump > heatercore heatercore>carb the weird thing about it is that it goes to the carb which has a double hose connector on it with abit of hose thats been blocked with a bolt an clip check out the pics any help would be much appreciated(this is my 2nd old car do up so im no expert) Quote Link to comment Share on other sites More sharing options...
Beaver Posted June 12, 2011 Share Posted June 12, 2011 if thats your heater core in the engine bay then there is no way you will get any heat in the cabin. it is normally under the dash and the fan blows air through the heater core (which is hot) hence getting hot air in the cabin Quote Link to comment Share on other sites More sharing options...
kyteler Posted June 12, 2011 Share Posted June 12, 2011 I assume he's pulled it out from behind the dash though, Beaver. To try flush it easier. The heaters in the Escorts were never too flash from the outset but it should still be enough to defog the screen, etc. Quote Link to comment Share on other sites More sharing options...
Beaver Posted June 12, 2011 Share Posted June 12, 2011 I never assume, it makes me look like (more of) a cunt Quote Link to comment Share on other sites More sharing options...
peteretep Posted June 12, 2011 Share Posted June 12, 2011 It doesnt matter which hose goes in which pipe, check that the fan blows a reasonable amount of air and that the heater box isn't blocked either in the airways or the waterways. Trying blowing through the pipes of the heater and if there's little resistance then it should be pretty good. To clean the air ways you really need some compressed air but if you can see through a good portion of the fins then it's probably ok. Basically to get it working as best as possible make sure everything is as clean and free flowing as possible I wouldn't worry about the blocked off hose on the tee, the elbow from the carb on my old motor corroded and had to be replaced, so someone may have replaced yours with a tee from a car with a dgav carb which would have used the tee line for the choke Quote Link to comment Share on other sites More sharing options...
Valiant Posted June 12, 2011 Share Posted June 12, 2011 Whats your thermostat like? Where does the temperature gauge sit when the car is running? If its right down at cold replace the thermostat. the vent controlls on the heater box could be causing you troubble too, not letting the warm air out.

dominic Posted June 13, 2011 Share Posted June 13, 2011 ^agreed with regards to thermostat In my escort, with a recored heater, any water temp less than 80 degrees at motorway speed will result in very mildly warmed up air. Around 90 - 100 degrees on the motorway is ok, and at slower speeds and its quite toasty. Just what i find with mine anyway. Quote Link to comment Share on other sites More sharing options...
89fordguy Posted June 13, 2011 Share Posted June 13, 2011 hoses look right. when i built my car i had my heater and radiator recored and the heater is still shit. Just escorts i guess Quote Link to comment Share on other sites More sharing options...
burrowssj Posted June 13, 2011 Author Share Posted June 13, 2011 thanks everyone for your replies an information much appreciated, I pulled it apart to check it for leaks it was of course originally in the dash I managed to get it fixed and blowing hot air! was so happy I decided to remove the whole system all together so I could check it for leaks an make sure it wasn't blocked, I think there was abit of gunk in it because when I stuck the hose on it with pressure it flushed more rusty crap out(why do people let old cars get to this state I really don't know) once it was coming out clean I did the same on the heater hoses, I have a feeling the T junction was to blame as I took it off an could visibly see there was rusty gunk all through it, flushed it out with the hose reassembled an it blows nice warm air out now! was totally stoked that it worked an I have a heater for the cold cold chch winters! thanks again all.. now just to sort the other faults of the car haha oh an p.s its a mk2 1600 crossflow automatic CORTINA (autos are shit I know but I love having the bench seat with column change) Quote Link to comment Share on other sites More sharing options...
