This is the description from Stewart's website, 1987-Up Passenger Cars and Light Trucks w/Belt Drive Pumps. CCW for serpentine belt.

The pump is about six years old and has been in storage for that time. It has never been used.

Asking $115 shipped.





Ecm from a '92 RS, has a custom Ed Wright Fastchip prom tuned for a 355 with a 5spd, ZZ4 cam, L98 aluminum heads and 670 TBI unit.

Whats the advantage of a stewart over a stock pump?
Do you know what mods they do to their pumps?
They're website is kinda vague as to what they do..

I'm interested in it..

I really couldn't give you anymore info than what Stewart says on their website.

The only thing I can say is that it only weighs about 5 lbs so it should be around 8-10 lbs lighter than a stock pump so that's kinda nice.

$100 shipped for the pump.

PM sent.

pm sent on pump

Payment sent via Paypal.

Water pump is sold.

Take $40 for the ecm.

Advantage is a 30% increase in coolant flow, as matched with their thermostat. I have their 3 holed 180* stat to match my stewart pump. You'll love it as I love mine.
