Oh,man, I'm getting tired just thinking about doing that. What if you just changed the fluid 2 or 3 quick times in a row, say on three different days. That would "sort of" do it, wouldn't it?

you could get 95% of it - it's the residual metal shavings and such that I'm worried about.

Actually, it's faster and easier to disconnect the cooler return line and let the engine and trans oil pump do the work after the pan's been dropped once.
#24 of 4968 Saturn problems by alcan Dec 30, 2003 (10:22 am)
Saturn engines don't have a camshaft position sensor. Camshaft position is picked up from #4 cylinder via the ignition module. A misfire on #4 cylinder will set the cam sensor code. Usually indicates it's due for new plugs and wires. Use OEM Delco if you want it to run right. Oil around the plugs, the owner didn't say whether it's an SL1 single cam or SL2 double cam engine. If SL2, it needs a valve cover gasket. If still extended crank or no start after plugs and wires, check fuel pressure. Should be 38-44 psi and hold there after key off. Another possibility re a no-start is a jumped timing chain caused by the nylon shoe falling apart on the chain guide. If so, the exhaust valves are dinked and the head has to come off. There's usually lots of warning in the form of a rattle out of the front of the engine for a while before the chain jumps.

It just freaks me out to be running the pump with fluid going out one side and hopefully coming in the other. What if you don't keep up for a minute there?

There'll be enough fluid left in the pump to provide gear or vane lubrication until the next bottle's poured in. I start with enough opened and handy to maintain the fluid level as it's being pumped out, and it's pretty easy to see the pump-out rate if the discharge is into something like clear 2 litre soda bottles (handy to have an assistant there to switch the discharge between bottles). Also, with the engine and trans warmed up, engine idle speed will be where it needs to be.
#27 of 4968 Now that sounds cool - this is by driftracer Dec 30, 2003 (11:42 am)
after you've dropped the pan and changed the filter, but before you add the rest of the fluid - swap it out on a one-for-one basis using the cooler line as a dump?

Okay! I'm convinced! Thanks for the details.
#29 of 4968 I've seen this done... by isellhondas Dec 30, 2003 (2:16 pm)
and it can be a filthy, nasty job!

under the car, the car on ramps, and an assistant?
