The Renix closed system if properly maintained is supposedly a great system...but I've always found it to be problematic. Between the odd hose setup and the pressure bottle and/or the pressure bottle cap usually being a piece of crap. I have converted both of my Renix rigs to the open cooling systems with 97+ hoses and a new radiator and no heater valve. I have had no significant issues caused by this conversion and mostly all positives. It's a fairly simple conversion, but it does cost around $200 (including the radiator and hoses and a radiator cap) for parts and an afternoon for a shade tree mechanic.
Same here. I'm of the opinion that if you need to replace the radiator, you're best off converting and getting rid of the fail-prone pressure bottle and heater valve. There are a few staunch supported of the closed system, but they tend to be the guys that spent a some effort getting it reliable and replace the bottle every few years.
