Hi All, I picked up an M&W P-2000 Dyno a few months ago. I've run it enough to learn how to use it, and get it good and warm. I decided to get the oil coolers fixed, because they were leaking. With them fixed, I'd like to know how to prevent that from happening again. It looked to me like somebody left water in the lines and it froze in the tubes of the heat exchanger and broke them. I also read about a problem with the larger dynos blowing up from steam pressure? I'd like to know: 1. How should I use the cooling system? The manual only says to run the water, but should I start out running the water? Seems to me if I wait until it's up to 180* and I turn the water on, it could crack the tubes from thermal shock. 2. Do I need to use the water each time I use it? Seems like if only using it for short periods, I can just let it cool off from 180*, if I even run it that long at a time. 3. Is it possible for residual water, if using it disconnected from water supply, to make steam and break the heat exchangers? 4. Am I WAY overthinking this?
Any thoughts or experience would be helpful! Thanks!-Andy
