I'm taking the coach camping next week for the last time this year. She runs a little warm at 60 to 65, 3/8 or more on the factory gauge. She ran that temperature all the way from Texas in 95 degree ambient temperatures. It will cool down when I reduce the speed, so from what I have read here, the radiator is not doing its job. I know the bottom exposed area of the core is pretty beat up from road debris. My plan is to remove it and have it recored. As has been written here by others, now is the time to do some other work since it will never be easier than when the radiator is out. So I plan to replace the water pump, timing chain, and fuel pump.
As a lot of the forum threads regarding these are older, and it seems the best choice of parts seems to change with the various Chinese factories making them at the moment, I would like to ask for recommendations for the best water pump, fuel pump, and timing chain choices.
I've read several threads regarding timing chain replacement. Opinions vary. Most people favor the Cloyes True Roller chain, and that is what I intend to use. However, some folks advocate the double chain version, while others say there is no reason to use it as the single row chain will outlast the engine.
Another advantage of the double roller version is the ability to retard/advance cam timing, which I don't think the single roller allows.
So recommendations based on experience, please.
Brand and type of timing chain?
Advance cam timing, or no?
Brand of water pump?
Brand of fuel pump?
Thank you for your opinions.
