fluid leak and try to leave town

I found a small puddle of pink fluid to the out board side of the generator at the front of our 2019 dutch star 4018. Is this automatic transmission fluid in the front of the coach. I don't want to drive until I know what it is. Thanks for any help.. David

Could be power steering fluid, or coolant from the generator. The power steering reservoir should be in the rear in engine compartment….see if it is low.

I also remembered the tank and pump for the hydraulic levelers is also in the front.

Agree with pasdad1. Definitely not auto transmission fluid though. That would all be centerline in the rear.

By "outboard side of the generator " do you mean , under the drivers seat; steering column area ?

What chassis ? Freightliner or Spartan ?

Only ATF I can think of in that location would be from jacks or slide mechanisms (hydraulic) or power steering that use ATF.


What color is your coolant in main engine? Heater core is up there with engine coolant.


Same for your generator coolant.


You should be able to feel/smell the difference between ATF and coolant.

I have since got underneath and can see it is a hydraulic reservoir. There are three of four of the cylinoids on top and it is leaking pretty good. I will try to buy the correct fluid and top it off. I have no idea what this is used for other than the landing jacks.

Same reservoir and pump are sometimes used for slide extension.


Have you identified the exact source of the leak? May be as simple as an O ring on a solenoid or could be a bad hose or even just a hose end that needs to be tightened.

That is your HWH pump that hydraulically powers your jacks and full wall slide. It shouldn't be leaking fluid unless someone overfilled it. You need to look to see if it's coming out of the cap, a broken hose or a valve.

IF this is an HWH system, you can use their CLEAR fluid or RED ATF.


Since it already has red fluid, suspect someone has previously added ATF.


Any auto part house/Walmart.

I suspect it is from your HWH system which powers you jacks and HWH slide. Ours had a leak when new and was due to a hose connection at the HWH unit that was no tight. Tightened the connection fixed the leak

Others have helped, but how long has your coach been sitting in that spot? Suggest to dry everything off and run your slides and levelers to see if you can make it leak again.
