peugeot 306 1.9td HELP!

Sounds to me as if your heater matrix is blocked up, sometimes you can clear it out with a hose pipe. I had the same problem with a Renault 21 not blowing hot air. I disconnected both pipes to the heater matrix and let the hose pipe run through it for 15 minutes. Re-connected it up topped up the antifreeze and all was well again. nice hot air. GGJ

Ding! Exactly the same on my wife's 106, brown rusty sludge the consistency of toothpaste came out when I flushed it

Hi!! Right...... The garage are right, the head gasket will be nothing to do with them-it is just standard wear and tear unfortunately. Ive recently had mine done. But.... from what uve sed....it dusn sound to me like ur head gasket has gone.... because the head gasket goin shouldnt have any effect on the hot air ur getting thru?!! Also head gaskets r EXPENSIVE, so be careful the garage arent trying to rip u off. Right, 1st things first. check inside ur radiator. Is there any brown gunk/liguid? secondly, check underneath the fuel cap. is there any water or a white solid inside the cap? If there is any of those then ur head gasket is probably going. Regarding the hot air, I would have said it sounds more to me like a wiring problem?? Coz if uve had the thermostat changed, i cant understand why it wouldnt work unless there is a problem sumwher wiv the electrics. Id be weary about this garage. r they trying to get u to pay out to get the work done? Hope this helps a little!!

I think you mean oil filler cap.

Could be a blocked heater matrix. Sometimes you can flush them out otherwise it's a right job to change them.

A second opinion is always worthwhile.
