Hazard

1. In the brake cooling circuit, due to improper circuit design, hydraulic pressure in the circuit increases at low temperatures, which may damage the oil cooler. Continued operation in this condition may cause oil to leak from the oil cooler, and in the worst case, oil may scatter onto the road surface.

Remedy

1. For all vehicles, replace the brake cooling circuit relief valve, hoses, and front axle cover with corrective parts, and replace the radiator with a new unit.
