Onan leaking coolant

[Tha_Rooster]

I have a onan 7.5 hdka QD when I put coolant in bottle it leaks out question how do I check to see if it's the bottle, hose or something else

Start by removing the top cover. You may have to remove more of the enclosure if you can't find the leak under the top cover

There are I think 4 hoses plus the tank. Remove the top cover to check. NOTE the three top cover screws holding the tank are a different length than the other top cover screws. Make sure you use the correct ones when putting the cover back on.

As you face the control panel, the three screws are the closest corner screw, and one each way from it.

Can all of the top screws be access without dropping the unit do you know how many screws and where? Not much clearance on top to see.

Rooster, there are screws on both sides and the back at the top edge as well as the top front. If you can't pull your genset out from the coach you'll most likely have to pull the genset from the coach. Mine slides out like a drawer for access. If you don't have access to find and remove the screws then you're not going to have access to find and repair a coolant leak either.
