Replace water pump

What I am really trying to find out is how can I depress the tensior so as to remove the pully and belt without removing the tenisor. If I can do this I want have to drop the AC compressor to remove the tensior thanks

There is a right and a left timing sproket I know of no rear timing gear on this engine, I am thinking you are refering to the right timing sproket ( gear ). I thing that might work looking at the front of the engine, is this correct?

Thanks that make since now, talk to you later with bloody knuckles

I did but I had to do it twice. I had a leak at the block behind the thermostat housing. I used a new gasket and put a little silacone on the out side of the factory sealer on the metal gasket, I think it called flipg. I had to remove the tenisor both times. I found it is easier if you put the belt on before tighting the tensior even with the pin installed. By the way the area where I had the leak was where the original leak was, and there was a little piting and I removed the studs and used a wire brush to clean the area. The only down side I think the radiator may have a small leak at the seam where the top is clamped to the core. I may have to have it reclamped. No visable leal but I can smell the coolant and it looks a little damp in that area. Thanks for asking and maybe others can learn from my experience. Lpeek
