Hi Joe

Find a garage that has one of these

If you remove the water pump and the shank if the broken bolts are exposed,try removing them with a bolt extractor.you may have to heat it up with a small torch. A propane torch used to sweat plumbing fittings will work.If the bolts are broken off in the block you will have to center punch them and drill them out.

Hi ,here's a guide on how to do,I have a 85 Nissan 720 4x4,just replaced my water pump,The guide isn't just right,to get to the bolts holding the fan on,we'll the radiator needs to come out,just 4 bolts,maybe 10 minutes.The pump is kind of hard,cause of the way the bolts are.I also replaced my 3 belts,thermostat and both coolant sensors at thermostat housing and radiator cap,the temperature sender broke apart,gauge wouldn't work,lasted 28 years.Had mine 20 years.Check out mine.Here's a site for 720 owners,join,it's free,I'm a member.

To remove the pulley wheel from the power steering pump you typically have to remove 3 bolts but to get to those 3 bolts you have to use a socket and go through the holes on the pulley itself.

Water pump is driven by timing chain idler and is mounted on the rear of the timing chain housing. Disconnect the neg. battery cable. Drain cooling system. Disconnect oxygen sensor connector.
Remove upper exhaust manifould heat sheild. Remove exhaust manifold brace. Remove lower exhaust manifold heat sheild. Loosen manifold to exhaust manifold spring loaded nuts. Remove radiator outlet pipe to water pump coverbolts. Disconnect exhaust pipe from manifold.
Pull down on the exhaust pipe to disconnect it from exhaust manifold bolts. Disconnect outlet pipe from oil pan and transaxle. If equipped with manual tranaxle, remove exhaust maifold brace. Leave lower radiator hose attached and pull down on radiator out look pipe to disengauge from water pump. Leave outlet pipe hanging.
Lower vehicle. Remove exhaustmanifold to cylinder head nuts. Remove exhaust manifold to cylinder head nuts. Remove manifould. Remove timing chain front cover. Remove timing chain tensioner. Remove bolts bolts securing water pump cover to cylinder block. Remove water pump to timing chain housing nuts. Remove water pump attaching nuts. Remove water pump and cover assembly. Separate componets as necessary.
WHEN INSTALLING WATER PUMP MAKE SURE YOU FOLLOW THE TIGHTENING SEQUENCES THAT AFFECT SEALING. My frist one I messed up and broke the pump so becarful.
Installation
If cover was separated from body during removal, join this componets with a new gasket and hand tighten bolts. Apply bearing grease to splines of water pump drive. Set body and assemble into position.
Install and hand tighten bolts securing cover to cylinder block. Install and hand tighten bolts securing cover to cylinder block. Installand hand tighten nuts securing body to timing chain housing. Lubracate outlet pipe "O" ring with antifreeze. (I use RTV) Connect outlet pipe. Install and hand tighten bolts. Tighten bolts and nuts to specification in the following sequence. I'll ad the torque spec. at the end but this is where if you tighten out of order something will break.
pump assembly to timing chain housing nuts.
pump cover to pump body bolts
pump cover to cylinder block bolts (Bottom Bolt First)
outlet pipe to cover bolts
To complete installation reverse removel procedure.
Torque specs are 19 in. or 26mm all except water pump cover bolts which are 124 in or 14Nm
I never torque the bolts just make sure there done in the right order.

you have to put M8 bolts in 2 M8 threaded holes on the water pump.

Here are some. Hope it helps =D

sounds like you have had a frustrating time.... sorry to add to it.... i believe the balancer has to come off to replace the timing cover.

I am sure the leak is the water pump based on years of Escort work, The ZX2 is equipped with a 2.0L DOHC V-Tech engine. The water pump is on the front (rt side of car) of the engine block, visible with the hood up. NAPA autoparts replacement instructions are to loosen the belt drive pulley from the pump BEFORE removing the serpentine belt. Once the four bolts are loose, take the belt off (good time to replace?) remove bolts and old water pump (four more bolts)- it will be tight, but it comes out- clean gasket area and install new gasket and pump in reverse order. That includes putting the pulley on and hand tightening the bolts, put on the belt, finish tightening the bolts to the pulley.

no need to pull the engine off. if you ar sure that there are no more bolts holding the water pump, tap it lightly with a hammer in the separation position . it is just stuck with the gasket. im sure it will come off the engine.
