(Peace, mercy, and blessings of God be upon you) Dear brothers, we offer you Impala engines with a 7-month warranty. We also offer refurbishment for the same engines, factory-new condition, with the same warranty. The refurbishment involves a complete change of the internal engine gasket with original spare parts and an 8-month warranty. The pistons, piston rings, connecting rods, gasket set, lifters, main and connecting rod bearings, valve seals, gasket set, and so on are changed. Manufacturing defects are generally addressed. Impala LT defect: overheating. This is addressed by widening the water circuit through the head and installing a high-pressure water pump. Impala LTZ defect: oil consumption and crankshaft knocking. This is addressed by widening the oil passage through the cylinder, installing a high-pressure oil pump, and completely cleaning the oil passage... We also offer free checks and inspections of external accessories, which are consumable parts that can cause long-term damage to the engine, and we inform the customer about them. These include the cooler, the intercooler, the radiator, the mounts, and all consumable parts in general. We also have a free tow truck service within Riyadh for our customers in Riyadh. We thank you and ask God for goodness, success, and guidance for all of us.
