2000 Winnie, Radiator Cap

I have a 2000 Winnie. Can not see where the radiator cap is located. Is there one ?

you are correct. there is none. it works off the reservoir only.

I want to flush water in my Radiator. My Winnie does not have a radiator cap. Does any one has a good procedure for flushing ?

the most likely way to do the flush is to open the valve at the bottom of the rad and then pull the top rad hose off. This allows the fluid to dump out and be flushed with water. Do all the safety stuff regarding capturing the waste fluid, check clamps, etc etc. I'd also pull the T-stat and replace with an OEM one, new gasket, flush the whole system. Pretty easy, although somewhat messy, job.

Thank you for the advice. A couple of questions:
1) Any suggestion for where to buy the Thermostat ? Adv Auto, Auto Zone etc or the dealer
2) If I take the T-stat out, can I some how use the garden hose to flush the fluids out ? or do I fill the Rad with fresh water and run the motor for 10 mins and dump out again and repeat this many times etc ?

A tip that is often overlooked... After flushing your system, be sure to not use regular "tap water" when filling the system back up. Either use distilled water mixed 50/50 with a quality pure antifreeze or buy the ready mixed 50/50 solution they now conveniently sell.

Too many tap water systems in the U.S. have highly mineralized and / or chemically treated water that is not good in the engine long term.
