KRC's all new CT525 complete crate engine kits are designed just for dirt applications. The water pump that comes on the CT525 has no provision for a mechanical fan to attach. KRC's kit replaces the water pump with a clockwise rotation Stewart Pro Series water pump. Also included is KRC's idler-tensioner to keep proper belt tension and prevent belt slippage when using a mechanical fan. In addition, a R-LOK crank adapter and pulley, Pro Series water pump pulley, water bypass fittings and hose kit, water pump fittings, water pump spacers, hardware and spacers and installation instructions are all included.
