the only real difficult hose is the one thats about 2 inches right next
to the distributor.... that one requires the removal of the water pump..

but the res should be easy... hose clamps use a screw driver or ratchet..

pull it off and all the water will come out immediately...

then just replace the opsite way you took it off... then fill with fresh antifreeze throw in some wetter water (redline) and take a drive.

this adventure will lead you into the spark plugs and the next thing you know you will be rebuilding your own engine.
