I am in the process of improving the cooling in both of our coaches. The Royale because I no longer want to use the engine oil cooler in the aluminum radiator (don't trust it after the three failed engines in a row), the Clasco because I don't think the stock radiator is as efficient as it could/should be for where we live (it is hot in the summer time and we have to climb mean grades of 1000 to 3000 feet no matter which way we go. In both cases I want to improve the transmission oil cooling as well.
I removed the front fender liners from the Royale years ago and saw an immediate improvement in cooling with no ill effects from water splash, so likely will do that on the Clasco as well. The Royale is a 78 so has the air deflectors stock and I already added them to the Clasco. Both have lower rock shields for the radiator.
So, here are my questions from the collective brain trust:
1) should I use active (fan assisted) or passive external oil coolers?
2) should they be placed near the radiator where the heat will be directed into the radiator or away so the heat is directed away from the radiator?
3) if near the radiator, should they be in front of the AC condenser or below it?
4) Looking at the back of the radiator the lower hose is quite a ways above the bottom of the core so it seems the lower part of the radiator would do far less heat exchanging than the top. Is that really the case?
5) any other steps you would recommend?
Thanks.
