Dwayne,

Motorhomes are allowed over the dam, though they must stop for inspection and a possible search.  The climb is probably 8%, but it's at low speed and low gear, so it's not difficult.  Unless it's the middle of the night, the delay with the traffic and inspection can be long.  I'll keep going around until they open the new bridge.
Regards,
Brett

Dwayne,

Our valve did NOT come pre-adjusted. 

And as I posted earlier, spec is max 2200 PSI @ gov RPM cold.  55 PSI would not even be in the right league.

What I did was install a "T" in the line from valve to fan motor.  Placed a gauge in the line to set it up and then just replaced it with a plug.

Verify with James that yours should be set as ours is, but summer and climbing grades 1500 would be the minimum I would suggest.

Foretravel sent an instruction sheet for the CAT tech.  I was travelling back to Tallahassee during install.  I would have to think that an adjustable valve would have the pressure spec included.  I am getting a very small puddle over a several hour period each time I stop the engine.  Seems to be coming from the valve rather than the fan.  The fan is slinging a very small amount of fluid.  It just looks wet around it rather than an actual dripping leak.  I looked closer at the install to see where the fluid is coming from.  The pressure relief valve seems to be inserted into a rectangular box (which is where the seepage is).  I'll bet some tightening will take care of this but I'd rather add fluid and wait till I'm home to mess with it as I have a habit of making it worse if I screw around with it.
