1. The PT Cruiser is a lot easier on fluids than the prowler, I'll probably only do brakes and trans every other year on the Cruiser.
2. A smaller extractor would work if you just want to do brakes, but the larger unit pays for itself (at least for me) since it can do the Chrysler tranny fluids without having to remove the tranny covers. It's a 10-minute job, also quite clean.
3. The brake-bleed kit is a necessity, and the valve works for other purposes - it keeps the vacuum in the extractor to reduce pumping. For the front wheels, the extractor is up front and you can add brake fluid while you watch and control the flow. For the driver-rear wheel, you can watch the flow (and the color) but you have to run from front to back to shut it off. For the passenger rear, you're working blind since you can't see the flow in the hose while you're at the master cylinder. Next time, I'm going to get a longer hose (plain old Home Depot type of item) so I can work the extractor from the front while I'm at the maste cylinder.
