In the name of Allah, the Most Gracious, the Most Merciful. Peace, mercy, and blessings of Allah be upon you. Dear visitors of Haraj website, we have H1 diesel and gasoline engines available with a full one-year electronic warranty. We also offer engine overhaul services with the same one-year warranty, which includes addressing manufacturing defects. This involves increasing the oil pump pressure by replacing the oil pump with a high-pressure one and widening the oil passages in the cylinder block. It also includes replacing the engine gasket set with pistons, piston rings, connecting rods, a full gasket kit, lifters, and so on. Additionally, we offer a free check of external accessories and will inform the customer of their condition. Thank you. Contact number: 0579790801
