[QUOTE="Riley P, post: 52023, member: 2"] Not really much for pictures on the reassembly. More just some pointers. The most difficult part is getting the gaskets to stay while installing the water pump. The problem is that the old gaskets were stuck to the block and after cleaning everything, well obviously the new ones won't.:D The only way I figured to get it completed was by installing all the bolts in the water pump, hanging the gaskets on the bolts and slowly sliding the water pump into the ready position. This isn't too easy as the bolts are just sitting in the pump and any forward movement and they want to slide forward and out of the water pump dropping the gaskets! So be slow and watch all the bolts. I lifted the pump into place about half an inch from the block and threaded in one bolt part way on the passengers side then one bolt on the drivers side. A couple difficult checks and I could see the gaskets were still in place so I hand tightened all the bolts. Finish torquing the bolts at 11 lb-ft on the first pass and 22 lb-ft on the second pass. Re-install everything in the reverse order you removed it. I never found any difficulty reinstalling the hoses, they went on quite easily but I've heard of people using a little dielectric grease or Vaseline to get them on. Now, double check every bolt and don't forget the electrical connectors. Make sure the hose clamps are back in the correct position. With everything buttoned up, start filling the serge tank with the old coolant if it is good or new DEX-COOL coolant. You can get the premixed stuff or the pure stuff and mix it 50/50 with distilled water. Don't use tap water or drinking water. I filled the surge tank with with all the coolant that I drained besides the stuff that came out of the water pump. This filled the surge tank up to the cold mark. I started the car and let it run for about a minute then put the cap back on the tank. I let the engine get up to temperature by checking the DIC and checked the level in the coolant tank constantly. The engine got up to 197 then came down to 195 so I knew it was at least cooling. I jumped in my car and went for a very short drive around the block as it goes up hill and back down hill. Once home, I parked the car and waited until the next day to check the level and the serge tank was almost empty. I purchased a gallon of the premixed DEX-COOL as I didn't need much and filled it to the Max Cold level. I went out for another drive and once parked, found the coolant was sitting half an inch above the cold mark. Lastly, the most important step in seeing that I had to leaks was sitting back and having a nice beer knowing my car is back up and running again! [/QUOTE]
