My 98 spartan chassis american dream is over heating when I am idling for any peoroid of time. I see the fan motor appears to be hydraulic. there is a round tank at the left of my engine compartment that appears to be some type of power steering fluid. My question is can anyone tell me what type of fluid tp put in this tank. It is low and I am hoping that my fan is not working properly at low rpm.
I just done know what type of fluid to add.
thanks

Why don't you call Spartan give them your vin number they should be able to tell you.

There should be a label on the tank specifying the type/grade of hydraulic fluid. Some say AW 46, I don't think mine is that high a number, more like 36. I would go look at mine (99 Spartan MM GT chassis) but I'm confined to my house, torn calf muscle. I just found this Spartan Chassis maintanence info: Spartan Chassis RV Maintenance Schedule | Brakes & Hydraulics - Part 3

There are filters in that tank also, might need changed???

jd956jd956 · 05-27-2014, 12:02 PM

Yes! There is a filter inside and it should be changed every other year. Changing it is easiest if you pump as much fluid out through the fill/dips stick hole as possible first. If that filter is old and dirty, it will limit fluid to the hydraulic cooling fan in lieu of to the hydraulic steering pump. The steering pump takes priority over the cooling pump. Spartan will provide you with correct filter part number.

do you have to remove the tank? or do you just remove the Top of the tank

Just the top of the tank, be very careful about contamination (clean hands etc.).

It may be worthwhile to have a heavy truck shop replace the fluid and filters at this point.

I checked the filter. My mechanic said he replaced the filter when whey put a new power steering pump on last fall. The fan is not working at all now. I am trying to find the sensor that tells the fan when to come on. I think it is either the sensor or the hydraulic fan motor is bad. you can turn the fan but not freely which I think is the way it should be.. Any help at this point would be welcomed

My 93 Pase had a temp switch on the side of the Cummins. off the frame between the engine & the side radiator is a nydraulic manafold with a couple solenoids. My fan has two speeds, low & high. Should be running in low all the time & will kick into high speed when the temp goes up.

Ok so I am at the Fleetwood, Spartan service center in Decatur Ind. The problem is a Valve body for the hydro. This directs 4.5 GPM to the power steering and everything else to the fan motor. The Fan on my unit is a single speed that runs all the time. It is not running now.(I installed a electric fan to get me here, Worked pretty damn good too) Thus the mechanic said that is why I am seeing MPG up to 9.8.. Damn the bad luck. He said when the fix the fan that will drop more than likely..

speedman42 · 07-09-2014, 09:05 AM

Wow the Service at Fleetwood was great. They have a lot with electric hook up for you to stay if needed. They also allowed me and my wife and dogs to stay in the coach while they did the work. They pulled us in a 6AM. They fixed our curtains that needed some of the tabs sown in, They fixed one of my basement doors for me, fixed my power gear leveling system, replaced proportional valves for my fan motor and steering (They are both Hydraulic and run off the power steering pump,) They also fixed a short in my electrical system causing me to loose all power.
The price for all of this $1245.00.! They have certified spartan chassis man on site. I am a very happy camper..
