search for a good detailed DIY procedure for TB change comes up empty.. Anyone know if there is a good one to be had round here?

Do I have to pull the entire radiator or just the hoses?

DrOlds

Just the hoses. Once you remove the front motor mount, you will have enough clearance to slide the crank pulley off. You might have to put some weight on front of car whle engine is blocked to clear a bracket flange. This is actually a pretty easy job if you have the tool to hold the crank from turning.

Thanks. Is there an easy or safe way to hold the camshaft pulley in place? or do you just mark it with a sharpie or something?

DrOlds

You need to keep the crank from turning so that you can unscrew the bolt that holds the pulley on. Torqued to 170 ft lbs, I believe. There is a hex shaped "key" that fits inside the pulley, and you brace this with a 1/2" socket against the front mount. Then you take your breaker bar with a 5' floor jack handle over it and unscrew that bolt. Then you can pull the pulley off, its keyed, don't worry about marking it, and then remove the lower timing belt cover that will be partially glued on with the melted insulation from the crank sensor. Remove belt, change water pump, and reinstall everything. Earlier steps will include removing all 3 drive belts and one of the tensioners. Also, remove throttle body and set aside for better access. Read the manual to reinstall timing belt correctly-their procedure to install and tension works well.

thanks, I guess the crank sensor meltdown is why I had a blob of sticky black tar on the garage floor a while back.

The crank pulley bolt can broke loose by using a 1/2 in breaker bar and socket then wedging it aginst the floor or car frame. Then have someone bump the starter while you hold the breaker bar and socket securley on the bolt. I would remove the ignition source by removing the coil packs first.
It's really easy and works quite well. I've done it twice now.

How do you hold the crank to re-torque? Chain wrench around pulley?

I 'm in the process of changing the W/P-T/B...I'm gonna attempt the DIY with pics and all...flying off the seat of my ass...Now in order to take the belt covers off, it looks like the crank pully needs to come off...correct? Is it possible to do it with an impact wrench?
Thanks,
Ron

Not usually
