Underhood Service targets repair shops that derive 50 percent or more of their revenue from the service and repair of under-the-hood systems.

The expanding amount of knowledge and capital needed to keep up with technological advances has led these shop owners to concentrate on underhood systems, while also offering preventive maintenance services on most major vehicle systems. Electronics, cooling systems, air conditioning, emissions controls, fuel systems, ignition, internal engine repair, electrical/charging systems — everything under the hood of cars and light trucks is addressed.
