in Australia, one in 1992 (GQ Series 2), and one in 1995 (minor facelift). The most notable changes in 1992 were the introduction of fuel-injection on the TB42 motor, EGR valve and oil cooler on the RD28T, new seats, new trim, sound deadening, and side intrusion bars. Other 1992 Series 2 refinements included a revised transmission and suspension, and introducing bigger brakes, bigger wheels, and the standardization of limited slip differentials and auto-freewheeling hubs. This update included new seats, trim, and side intrusion bars. In 1991, the rear indicators, tail lights, and brake lights were relocated to the bumper from the body to meet Australian Design Rules, but they stayed the same in European versions. In 1992, another set of indicators was placed on the front quarter panel. In August 1993, the TD42 lost weight to reduce fuel consumption and increase maximum engine speed. This had the side effect of weakening the engine. The original engine can be identified by its silver rocker cover, whereas the lightened engine featured a black rocker cover. The RD28T got some extra changes, moving the vacuum pump from behind the alternator to the top of the engine. Driver-side airbags appeared in some European models. Changes in 1995 featured a minor facelift, with a redesigned front grille and the RX model entering Australia. Known weaknesses included vibrations from the front end (largely fixed under warranty), cracking hinges on the rear door (due to the spare tyre's weight), and rust on rear window frames. The RD28T and TB42 engines suffered from head gasket issues when driven with a heavy foot. European five-speed gearboxes suffered from bearing failures in fifth gear at high mileages. However, the TD42 was highly reliable. Patrols are known for their strong axles and good limited slip differential (when so equipped). From 1988 to 1994, Ford Australia rebadged the Y60 Patrol as the Ford Maverick. This was a result of the Button car plan devised by the government of Australia. The car was mechanically similar, although the Nissan version had rear disc brakes depending on vehicle grade, while the Ford mostly had drum brakes and featured different paint colours and trim levels. All wagons had a 95-liter main fuel tank with the utility having a 90-liter tank and the option of a 95-liter second tank.
