coolant leak

[we350z]

Cool - where exactly is that drain plug located on the block? how do i get to it? Pics? While draining should I jack the rear up to try and get more of the of the old fluid out? I'm not quite sure i get what you are saying about the pb blaster on the water pump with respect to the coolant pipes? can removing the wp itself or installing the new tstat dislodge the pipes or are you talking about re-assembly? Confused.

As for the tubes, I usually spray some penetrating lube on the front of them (at the back of the waterpump) to help loosten the front o-rings and keep the rears intact. And when you refill it have the bleeder screws removed when you fill it to the top, then put the bleeder screws back. With the main fill cap still off start the X5 (with the heater on as well) and you should see a stream of coolant pissing across the opening. Have someone hold the throttle to about 2500rpm and the stream should be solid and strong. If that is the case you should be good and fully bleed. and you can go ahead and cap her off.
