JD60,
Lots of good info given. Two points I don't see, though. With a 50/50 mixture of water / glycol antifreeze, your boiling point gets to 227 degrees F. If it's rich, let's say 70%, it will boil at 238 F. The above numbers are for an unpressurized system at sea level, 1 bar or 14.7 psi atmospheric pressure. My 60 has a spring on the radiator cap. Not sure how much pressure it provides, but let's say 4psi. At anywhere below 1000 feet above sea level, that usually means a boiling point of 236 F with a 50/50 mix and up to 260 F with a 70% mix, and 225 with pure water. At 200 F, you've got a lot of headroom. The downside of antifreeze is that a 50/50 mixture has about 12% less heat transfer ability than pure water as it flows slower through a pump and has more "surface tension" to surrounding metal. The other factor worth knowing is that if you blow a head gasket - water just becomes steam in the cylinder, while glycol does nasty things to clyinder walls and pistons. For more info, the world's greatest concentration of heat exchange experts are oldertimers in Arizona who've lived with swamp coolers! -- but it sounds to me like you're not in too bad a shape, just flush the system, blow out the radiator fins with high pressure air and refill knowning that more antifreeze in the mixture gives higher temps, yet higher boiling points.

Torque Wrenches - by Curtis Von Fange. When working with fasteners a torque wrench can play an important role in the correct assembly of critical equipment components. Lets examine in detail some of the reasons for using a torque wrench along with how to correctly use the variety of wrenches available. Applying the proper torque to a fastener accomplishes a number of tasks. First of all correct torque will hold the parts together. This may seem like a trite statement but � think about it for a second. Engineers have designed
