Oil in overflow bottle

May 10, 2010, 08:38:47 pm

Well I found the drain for the radiator and after draining all the coolant I found oil in the overflow bottle, not a good sign at all!! Since it was clean looking oil, my assumption is a leak in the hydraulic oil cooler mounted next to the engine radiator. Would anyone in the group know who made the hydraulic oil cooler? I have a call into FOT for help too.

Thanks,

I wanted to change the coolant in my coach before my big trip and wanted to see if someone in the group could give me a little help on the procedure? I have given a quick look underneath and did not see a drain plug or petcock on the radiator. So have a missed the location or do I need to remove the lower hose to drain the coolant or is there another drain location?

Thanks in advance,

Brad
