"<#<"WaKaBam:">#>!!" The first water-pump on the Ford 1500 Shibarau engine (20 hp) lasted twenty years, and the rest of the components of the engine have never been a problem; however, if you run it out of fuel, it will be a (PITA) too! I do change the anti-freeze on the tractor more often than the others, that have had equal use, and with a higher concentration of anti-freeze for lubrication. The first water-pump lasted a couple thousand hours.
Also, welcome to this site, there is an infinite amount of talent here!!
