Three weeks ago, I popped the coolant tank on my 89 XJ 4.0. It's been too cold outside to get anything done, so I put a blanket over the engine and a trouble light on under (whats left of) the hood. After getting the water pump off, I discovered ice in the block and a tasty-looking green snowcone slushie as well. The water pump impeller had sheared loose of the pulley shaft, the thermostat is locked in place, and I blew the heater control valve in half. The engine actually still runs, no sputters, ticks, creaks, or white smoke. I run it for about 1 minute every day to make sure it still works, and it is flawless in operation. There is no apparent separation at the head gasket, and no cracks in the block or head, no warping in the head. I discovered the radiator was well on it's way to going bad, and the hoses are screwed.
Would any of you recommend for or against thawing the block out, throwing on a new water pump, thermostat, radiator, hoses, heater valve, and coolant tank, and seeing what happens to it? Could the block and head be damaged at all?
