The Auto Channel, eBay and ASAP Motors offer ways to find Jeep engines. Both eBay and The Auto Channel host listings of currently available Jeep engines with prices. ASAP Motors and Transmissions has an online form to request the exact make, model and year of the part desired.
If any of ASAP Motor's suppliers has the part in stock, the suppliers reply by email with engine information and a price quote. The Auto Channel includes a star rating describing the engine condition. Included with each engine description is the mileage, size and warranty length. Jeep engines on eBay are sold by third parties, but eBay offers a money back guarantee covering fraud or items sold with undisclosed defects.
