C5 starting procedure after 18 month layup?

[panrixx]

What is the best starting procedure after a 18 month layup? My C5 has been garaged in an 'AirFlow air bag' but temperatures have been down to -10 degrees C.

Do I change the oil and filter first, or after giving it a run to drag any minute debris/rust into the oil filter before changing? The old oil had only done a few thousand miles and was Mobil 1.

Should I drain the 18 month old fuel from the fuel tanks and, if so, what is the best method?

Is there a way to 'prime' the oil before starting the engine? I know that older models could be primed via the distributor shaft, but what about a C5?

Are there any other precautions/actions to take prior to firing her up?

Any help would be very much appreciated.

Thanks 6 shooter, that has helped.

The article says to change oil and filters first. However, if the engine has any slightest rust on the bores, etc, won't that just end up in the new filter. I wondered if running with the old oil and filter first would act as an initial flush out before the new components go in. What would be the adverse affects of doing it this way around?

Is your vette a manual or auto?

It's a year 2000 auto.

Mines a 2000 also, but it's a 6 speed manual. If ya had a manual you could turn it over without having to fire the engine, just give it a bit of a push and pop the clutch to lube the bores and such.

I'd say change the oil prior to running it, then run it with the new oil for a bit and change the oil again.

If the car has been stored for 18 months you can waste a lot of time on all the various feel-good ideas but the best way is to:

1) Make sure the battery is charged.

2) Start the engine and drive it until it reaches operating temp.

3) Wait half an hour then change the oil and filter.

If it's been more than 3 years since the last coolant change, I'd change the coolant.

If it's been more than 3yrs/36,000 miles, I'd change the trans lube, the axle lube, the power steering fluid and I'd flush the brakes.

Then...enjoy the drive.

Almost Hib,1 warm up cycle isn't enough to catch whatever might wash loose inside!
I'd drive it 2-3 Good warm up cycles before I dumped the oil,unless it looks like Texas crude to began with!!
