HOATG05 should be flushed and replenished every 5 years or sooner. The power steering requires ATF4. It does get dirty that PS fluid and it should be flushed out as well. I now use a mixture of ATF4 and LubeGard power steering fluid which immediately quietened down the pump and it now runs cooler. No stiff steering when cold either. I suction out the PS fluid once a year from the reservoir and get clean stuff in there.
i was kinda shocked to see this too i cant see how towing would create a need for a cooler for power steering fluid. a tranny cooler on the other hand would have been a better choice.
package but why a power steering fluid cooler also I agree an oil cooler would be nice also.
Maybe its because some people dont know how to back up with a trailer and theyre always cranking over the wheel. Or for slow speed trail climbing and having to make a lot of steering inputs. Theres a sythentic PS fluid out there. DC probably should have just done that instead.
is it the hard line that loops from drivers side to passengers then back to drivers on the front crossmember I think its there to act as a fluid cooler of sorts for the PS setup
ATF4 is used both in the transmission and power steering. I would personally suction out what ever is in the power steering reservoir when hot. Note level. (ATF4 Compatible synthetic) Then replace with Lubegard power steering with LXE....this stuff is good and will keep things in smooth quiet working order keep seals moist and help when cold. I used the 32 oz bottle as in this link 10. My pump was
Torque spec is 105 in lbs on the 545RFE transmission and 15 ft lb on the 42RLE. Never unhook your cooler line and pump out the transmission thats rediculous. If you change your oil every 30K the trans will last a very long time. All unhooking the line does is what someone else mentioned burns your pump up. Same kind of pump as your power steering you run that dry and what happens it whines and eventually

Section 19 page 20 in the service manual The power steering fluid cooler is located at the front of the vehicle.
All KJs as far as Ive seen have PS coolers in addition to the transmission cooler. The reason for the power steering cooler is DC has had problems with mini vans overheating the power steering rack they had a problem while testing the KJ in the real world(Rubicon Trail) with the power steering overheating so they all get a ps cooler. That is why the correct power steering fluid for any Chrylerjeep
really irritates me The 100 oil changes I meticulously followed every 3200 miles were with mobile one 0 w 40 an API CF oil an oil that IS NOT designed to be used in a diesel engine with an EGR AN EGR THAT EVERYONE IS FINDING CLOGGED UP AND SOOTED... The US MANUAL REQUIRES ONLY THIS OIL yet the car was supposedly delivered to the dealerships with a different oil MY CAR WAS AT THE MARINO CHRYSLER jeep
try to trace it out. my 05 liberty has a power steering cooler an AC condenser and a transmission fluid cooler that all run hoses around that general area it could be any of them. Have you run your AC since you noticed this
motor and 545RFE trans. 2. No info on the cruise yet but once mine is in and running I am going to try to make it work. 3. The truck NVLD is needed for full emissions in Cali. I am using my 98 tank with an 06 fuel pump. I am going to adapt the 06 truck NVLD. I should research this a little more actually because if I could use an 05-06 wrangler setup in the factory mount Id go that route. 4. jeepSpeedShop
