Type 4 cooling advice

Discussion in 'Mech Tech' started by Byron Bamboo, Sep 10, 2017.

  1. Should these be blocked up with rubber bungs?

    Just taking exhaust off to clean up as it's all been fitted with exhaust sealant and a mess and noticed these rubber bungs.

    Also note that the exhaust has been getting mega hot, so hot the heat exchangers are going white.

  2. someone has put them in there to stop the airflow through the heat exchangers which in turn stops any neat coming into the cab. maybe your heat exchangers were leaking. so no they shouldnt be in there but you need to investigate why they are in there
     
  3. No there should be little aluminium flaps ... someone on here used to make/sell them.

  8. You need flaps if you have the aux fan as they prevent hot air being blown back in to engine when at idle

  9. On another note:

    Is there something missing on the end of the fan shroud casting (4 bolts)?

    And is there usually any more tinware around the oil cooler?

  10. nothing missing off the end, its where an AC compressor can be bolted if it is ever fitted. i think the oil cooler is missing the brackett that supports it. it will bolt into the top left hand of the 4 bolts
     
  11. Yes support bracket is missing

    Where that masking tape is ...there should be a steel pipe entering the top of the heat exchanger....and a pipe going to it from the snail fan at the top in the engine bay.
    Your best looking at a fully working heating and cooling system on a type 4 ....looks like your missing under tins too ....All of it is important .

  18. Also looking for a set of cooling flaps.

    In the states on this engine they'd left in the oil cooler flap and welded it down.

    Anyone got a set?
