What was the gauge doing? Was the radiator fan coming on at all? Did you
ever hear it kick into high speed? I would at least put the 2.1 radiator
temp switch in if you don't have it now. Then of course you should purge
any air out of the radiator so it will cool as best it can. It is pretty
simple to add a switch in the dash area so you can manually kick the fan
on at its highest speed if you find the temp gauge rising too high
without hearing the high speed come on.

What steps can you suggest for cooling our engine? We are running a Bostig. We have a tool box (Harbor Freight trailer tongue box) up front which partially covered the lower vent area for the radiator. We removed the lower portion of the grill to increase air flow.  That helped.  Then at one point we took off the tool box.  That helped too. We thought about cutting the opening larger, behind the main grill.  We know that the box was blocked some air flow, but we are going to need to put stuff up front on that metal tray (see photos)..... what else can we do to reduce temps?  Oil cooler?  Two stage fan motor? Different fan switch?  Water Wetter or similar, as discussed here? Any other suggestions?Geneva 1985 Vanagon with Bostig
