pm26 Posted December 3, 2011 Share Posted December 3, 2011 All,Been away from the forum for ages - just really running my car into the ground until I hit the magic 21!However, with winter fast approaching (already here ) I noticed that my heater does not blow very hot (yes I have engine temp!). I'm about to go outside and get behind the glovebox, but does anyone know any other possibilities? The engine temp rises fine, so my immediate guess is that the cabin filter is a bit clogged up!Any help would be great Cheesr! Link to comment Share on other sites More sharing options...

markheaysman Posted February 23, 2012 Share Posted February 23, 2012 Hi, Unfortunetely I know the problem, it's the heater matrix.I used to work for Valeo Climate Control as a test engineer. Valeo used to make the whole heater system for the Honda Civic as well as Rover models.The heater matrix was made in-house by Valeo and one of it's major problems was a displaced or incorrect fitment of the rubber baffle seal.This seal is situated in the top tank of the heater matrix, it's job is to stop water from flowing straight from the water inlet to the water outlet. The correct flow should go down one side of the matrix and up the otherside to the outlet. When this seal is not positioned correctly a percentage of the water just goes straight in and out of the matrix, thus reducing the available heated water traveling through the heater core.Obviously depending on how much of a percentage leaks past this seal effects the heaters output.We used to do a test, which was called a baffle leak test. The specified max limit of leakage past this seal should not exceed 1200cc per minute, take it from me a lot used to fail or just pass.As we only tested a very small amount that were actually produced, a lot of rubbish must have been put in cars.My first Aerodeck had a poor heater, but luckily my VTi's is ok.Hope this helps explain that Valeo's to blame for producing such crap heater cores.If I'd have known I would have acquired some perfect ones, would have made a fortune. Hindsights a wonderfull thing. Link to comment Share on other sites More sharing options...

FREAKBOY Posted March 7, 2012 Share Posted March 7, 2012 Well markheaysman covered that pretty well. Another option is that the matrix is clogged with gunge. A trick I have done before is to remove the water pipes to the matrix somewhere before it passes through the bulkhead, point one and the floor and attach a hosepipe to the other end, turn the tap on. If little or nothing passes through it's likely clogged. Run the hose for a while to clear it through. I've done this on sooo many cars over the last 20 odd years it's unreal. It's so often the case when you turn the tap on you get trickle..... trickle....blip..trickle....cough....trickle...lump.. trickle... gush...flow.. as it clears 14 years worth of poo from it's innards onto the floor. Oh and radweld really f**cks heaters up too. Quite often the simple things are overlooked. Link to comment Share on other sites More sharing options...
