    Default 604 heater

    Well seeing as winter is fast approaching i thought i would catch a nice warm day to put the heater all back together in the 604

    going back to xmas time the 'O' rings that seal between the heater tap and the matrix decided to die while travelling along into Bathurst for a family xmas day together

    after all the festivities my brother in law and i decided it was time to bypass the heater tap so we could continue on to Sydney on boxing day for the rest of the family get together

    we used a piece of copper pipe and joined the two hoses together inside the car and then proceeded to top up the coolant again after new stuff was only put in the car a matter of days before hand

    anyway a while after that i found the car had a slightly blown head gasket so out came the chemi weld and fixed that up but the car still seemed to overheat or get hot way too fast

    so out came the thermostat and found that it had fallen in half inside the housing, so i replaced that with another one to which i also found that the gallery to the overflow bottle on top of the thermostat housing was blocked up with rusty coloured gunk so that was cleaned out

    i then decided to replace the radiator with another known good one to see if that cured the getting hot too fast syndrome and it did so that was another step in the right direction

    all this time i was running a very weak coolant mixture in the car which had to be replaced with new stuff but i wanted to be sure everything else was going to be working the way it should be first

    so today was the day to attack the heater tap and get it all back the way it should be without it leaking coolant all over my left foot while driving

    i went down to the local bolt shop and picked up a pair of 'O' rings for the grand total of 40c

    put them in place and put everything back together and the replaced the drain plugs in the engine and radiator and proceeded to fill it all up

    started the car and ran it through all the normal bleeding of air to find the heater tap was dripping

    checked the screws to make sure they were right and it still dripped and then it stopped

    bloody beauty i thought but to make sure i ran the car for around about 3/4 of an hour in the front yard and still no drips

    then i thought i'll see how hot the heater is the fan has decided to go on holidays

    tomorrow i will chase the wires back to see where the problem lies

    but it was all in a days fun and more fun to go with 1/2 a dash to be pulled out but i know there is a loose connection there somewhere as when i fiddled with the switch it would start up and shut down and i tried another switch for it to do the same thing

    just thought i would share that with you guys

    ah yes it is all good fun

    well i found the problem with the blower fan and all it was was the little switch on the lower heater control

    a little bit of CRC in the switch and all was fine again

    while i was there i fixed the glove box light and the courtesy light next to the glove box

    the next job will be changing the passenger side door lock so i can use the same key in either door and the ignition switch that way i'll have one key for the whole lot

    electric central locking and a wheel alignment will be the next jobs as will checking the rocker clearances which i keep putting off it's a pain to get to the right hand side with the A/C sitting on top and the lack of room getting the rocker cover off from under the brake booster
