are you suppose to remove the timing chain tensioner in replaceing the water pump on a 1996 nissan maxima?

Question

i just want a 2nd opinion because the book says the job can be performed without removing timing chain cover by removing the timing chain tensioner.

Answer 1

Do it all the time remove the two black covers remove the tensioner from the rear cover. Take your time place rags around and tuck them in so when the last bolt comes out the tensioner and unloads the spring and push slug does not fall into the chain cover then as the book say turn the slack by rotating the crank slightly remove the water bump bolts. Then using 2, 8mm all threaded bolts in the two threaded holes on the pump flange to pull the water pump out. You did drain the engine block drains and pulled out the special drain bolt by the thermostat. If you get antifreeze into the chain case you must change the oil also. A word of warning old design chain tensioner might take forever to pump back up. That can be prevented by installing the newer design chain tensioner. 1997 and up have the fast to pump back up tensioners. It will rattle like heck and sometimes takes 30 miles of on and off the throttle driving to pump up an old style chain tensioner. You never have to remove the chain case(s) unless you want to repair that oil leak softening up the right lower control arm rear bushing. And use vasoline or light grease to lubricate the new water pump's o rings. and you should be able to push it all the way back in easily and replace the 3 bolts

Answer 2

I would not for any reason let someone who is not experienced with vehicle touch your timimg belt. If they make one slight mistake you will be screwed, You can bend your valves. So no no no dont do it that way. Cause if you cant afford to have a professional do the water pupm and timing belt which is always best to do together you wont be able to afford for some to change you bent valves. Find a shop that will let you make payments..
