Heating Problem

I've just noticed when i've got the heating on Hot it seems to only be giving cold air and not hot?
The fans are set so they running all the time but surely that wont be causing it

How hot does the car get when you have been for a run or does it get a little warm when you have been driving for a bit? id take a guess that somebody has took the thermostat out. ...

Leighton the temp just slighty stays over C?....Well under halfway even after a good run? The thermostat is still there but the fans were kicking in past halfway and car would show overheating hence the reason the fans are always on now

try flushing the rad had same problem with my honda

I need to do that as i need to know what aquamist injector system its using(am useless Leighton)so i can use the correct stuff

How do you know the thermastat is in place?

Pulled the hose off to check and it was there

more than likely the thing is airlocked
put your hands on heater pipes going into bulkhead if one is cold then its a blocked heater matrix under dash, if both pipes are cold then its either airlocked or possibly a blow on headgasket pumping air into coolant system
this is all assuming your stat is working correctly

A blow on headgasket? does that mean headgasket is knackerd?
I'll check as soon as am home from work if both pipes are cold?

another thing to try is let it run with the rad cap off and get all the bubbles out and that will tell you if its got an airlock, rad flush worked for me slightly as it was blocked up at the matrix so pour some in for a week or so then get the system flushed out

Thanks for info
I have noticed that the heaters are blowing warm air but not Hot and the rad cap doesn't seem to be hot enough to burn your hand like it normally does?
As Bob said i checked the 2 hoses going to the bulkhead next to the fuel filter they were both boiling hot and so was the hose going to the thermostat

If thats the case have you checked the slider cable? to make sure its flipping over to hot?

if both hoses are hot then water must be circulating through the matrix but sometimes if some of the waterways are totally blocked then water will bypass them and run through the unblocked ones.
if i ewr you i would disconnect both pipes from the big metal pipe and put a hose on there and back flush it under pressure.
then do as digifaze suggested above

the only other possibility is your slide heater control is not working correctly hence not shutting off cold air valve as it should do

slide heater control is that the thing thats on the controller cold to hot sliding button??

yep

Great minds think a like lol. .... Hopefully its this usy

Yes mate you should hear it flop over a flap or something like that. maybe try chase the cable down to the matrix to make sure you can see the arm moving im not entirely sure with the pulsar matrix ive never had the pleasure and hope i dont either lol

il be giving you a job next lol

Im not sure you could afford the tea bill bob

Lol its me leighton
Sorry which 2 pipes do i remove to pressure flush?

Have you checked the cable first make sure its working on the matrix before you go stripping shit off. ... I presume bob is on about the two pipes you checked to see if they were hot the one to take of is the one that goes on the big metal pipe from what i gather from what bob said is that must be the out on the matrix so by pushing water down that way it will be back washing the matrix. ... Am i right lol

I'll check the cable first Leighton
If nothing i'll blow the pipe

yep your correct leighton and i bet i can drink more tea than yow lol

Hmmm i can see a tea off coming on lol

Got to the problem it was the cable..
Just need to tighten the cable
