Great video! Thank you! After watching I was able to find the oil leak on my daughter's G6 and then replace the seal in a couple hours - after my mechanic diagnosed it as an intake gasket leak, paying him $1,000 and bringing it back to him 4 times! Not having a socket that large, I used a 1.5" pvc coupling and a piece of 1.5" pvc about 18" long to drive the seal in. I also learned that the pulley bolt is a torque to yield bolt that is supposed to be replaced - about $18 at the dealer.

I went to a tech school for a year, graduated to of my class, it was a joke, waste of a year, I could've passed without even trying, all we did was hang out a shoot the breeze and read a chapter or two and take a test on it every now and again, and once in a while do some repairs. I used my time wisely though and was studying by myself about driveability diagnostics and electrical, and CPU controlled systems... which is all cars now days... they was in there having us turn rotors and drums on a lathe... shit we will never do in the real world today unless you work at a machine shop...I really did learn allot from KZbin I ain't gonna lie... more than one year of tech school for sure!! hell when I'm at work and don't have access to service information I'll just whip out my phone and KZbin something real quick if I've never dealt with it before... it beats b not knowing what your getting into and just winging it and maybe creating more work for yourself. I always thought that if KZbin keeps going the way it is, theb only reason ppl will need a mechanic is because they don't have all those expensive tools. hopefully I won't even need to get my hands dirty soon if I can work my way up to be the go to guy for diagnostics.

I get conflicting answers on whether or not to put sealer on the outside of the seal or install dry. I do know the inside needs oil.

I use petroleum jelly to keep it lubricated, I would not use gasket sealer. It's already a 'seal'.

[@zuilok]

All good untill the very end. You are never supossed to use the bolt to drive the pulley back onto the crank. Because the bolt will in the beginning only engage on a couple of threads and you can strip them right out of your crank, you really dont wanna do that. Also the bolts are often stretch bolts that are one time use only. And it is never recomended to use an impact to put them back in once again because you really dont wanna strip the threads in your crank.

Nah its fine

I couldnt tell by watching and i dont think you mentioned it, but you should put sealant in the keyway of the pully before installing. Without sealing the keyway, you could have an oil leak.

Hi..yes u need a puller..the balancer is pressed on..don't forget to subscribe

[@aironnoles5588]

At 6:49 if your balancer lands look like that there's a chance it's going to leak ; due to the seal wearing grooves into the balancer's seal contact surface . Your options are to replace the balancer ($40-$300) , weld the grooves then machine the weldment back down to size ( dont know how much that will cost since I've only done method one and three ) , or use a re-sleeve kit ($40-$50) .

[@michaeldvorak5556]

Correct. Those balancers are aluminum and do get grooves. Depending on location of existing grooves, you could set the seal deeper so it rides on new metal. Doesn't the reserve kit come with its own seal sized for the larger diameter?

[@aironnoles5588]

I tried wedging a piece af wood between the balancer pulley and another pulley and no luck . The balancer would just turn trying to break the balancer bolt loose . I knew what I needed was impact tools but didn't have the money for impact gear ; Nor did I want to remove the radiator. . So I disabled my fuel injection system and put my breaker bar and socket on the balancer wedging it against the car's frame . Then I turned the motor over with the starter ; broke the bolt loose the first try . When I was ready to put it all back together I tightened the pulley bolt with quick jerky movements on the breaker bar similar actions that an impact would do , which makes me wonder if that's enough torque taking in account that the bolt will self tighten anyway when the engine starts running . Another option was to turn the engine in the reverse direction then quickly tighten it in the righ direction using momentum in my favor but no luck in free spinning the motor in reverse direction ; I did not remove the spark plugs which would have relieved any compression in the cylinders maybe making it easier to free spin the motor .
