Is there a power steering oil cooler in front of the radiator on 1993 Chevy Cheyenne 4 wheel drive work truck?
No, a 1993 Chevy Cheyenne 4x4 work truck does not typically have a dedicated power steering oil cooler mounted in front of the radiator. Power steering fluid cooling is usually handled by the fluid passing through the power steering pump and potentially having some heat dissipated through the pump's casing. A separate cooler is much less common in vehicles of that era and type, especially a work truck.
