(In the name of Allah, the Most Gracious, the Most Merciful) Peace, mercy, and blessings of Allah be upon you, My dear brothers, we offer you Chevrolet Silverado engines with a 9-month electronic warranty. We also offer you the refurbishment of factory engines with the same warranty. The refurbishment involves changing the entire engine gasket with original spare parts, including main bearings, connecting rod bearings, lifters, piston rings, valve seals, pistons, gasket set, connecting rods, and so on. Manufacturing defects are generally addressed. Silverado 6-cylinder defect: Overheating. This is addressed by widening the water circulation path through the head and installing a high-pressure water pump. Silverado 8-cylinder defect: Lifters. This is addressed by replacing all lifters, widening the lifter passages, and increasing oil pressure. We also offer free inspection and check of consumable parts that can damage the engine if not replaced, and the customer is informed about them... Of course, the cooler, condenser, radiator, mounts, and all consumable parts are checked. We also have a free tow truck service for customers within Riyadh. We ask Allah for success and guidance for ourselves and for you. Note: If you do not receive a response, please leave a message, and we will respond as soon as possible.
