The easiest way I have replaced a water pump, is when I had the engine sitting on the ground looking at me.
seems to me if the plastic on the radiator is going to break just removing the hoses, maybe it was time for it to be replaced too. every so often it is recommended to replace the hoses, are those not going to be changed from fear of breaking the radiator?
removing the radiator will give more room to work. also a good time to blow out the radiator fins and ac condensor.
that lower oil cooler clamp can be a bugger to get back on. It`s just like the top one, just reversed.
