Robis Pinzgauerforum

I’m having difficulty bleeding air from the heater circuit part of the water cooling. Engine part is ok but no heater due to air lock. Any ideas would be appreciated. Sorry I don’t speak or read German.

Welcome Martinpk222, to Forum.

First tell us which type of water circulation do you have. There was 4 main typs and different up-grad versions ( search function top right ) . To dedicate your system tell your Vin Number and/or show pictures of the opened service flap on front nose and pictures of the left engine side+ top view.

If you can localize the area as heating circle, remove all hoses from metal tubes, because there is rust between tubes and hoses-so air sucking in, also remove and check the black heating valve under dashbord left side, by see-through check if white sealing shim is damaged and particular drops running at regulate shaft out- so air bubbles also can get in system. very seldom the heater it self get air-unseal- more leaking water.

Note: if you swapped the cooling liquide completly , it takes some time to get all bubbles out of system...

Hi it is version D I believe. With by pass valve on thermostat installed. It also has only the expansion tank under the hood at fro t of vehicle. I have disconnected many lines and filled with coolant before running. I will check to make sure all hoses are sealed too.
I will get pictures soon.

How do I insert photo into forum? It won’t let me?

Hello Martinpk222,

ok, by VIN it is a P93 Execution ; station waggon, Intercooler with Auto Box,RHD, with Version D water circulation -the last one, including pre-running E-Pump with bybass system, watch to for system D shematic here

for your model you have to search after pre-setted sign "P" at all groups, be carful there are differents in bloc https://www.puch.at/en/products-spare-p ... servoir-p/ it shows the same shematic like RHD , but part numbers are LHD- no RHD P93 free parts book online available.

To reduce translation problems or disproportion , it make sence to limit the search by telling the tabel of contents or better construction group ( OEM spare part system)

https://www.puch.at/en/products-spare-p ... nt-supply/ check all shown black painted hoses for setting ( refit all screw crap (hose clip number´s 3) ) and check pipes 22 +23 before for under-rusting in hose setting areas (some are rusted through below)

For the heating regulation valve group are no pic´s available ;it is this one ( pics shows one with loosing four outside cramps ) https://www.ebay.de/itm/Mercedes-G-W460 ... Sw~zde3SYQ check exactly the white shaft for dropping water, water running lanes..much air get´s in but low water loosing. note or photograph direction before dissasamble ( flow direction !) arrow sign
