These pictures illustrate some of the mods that have been done to my ZD30 Patrol.
The Intercooler was ordered from Cross Country 4x4 and supplied with a 10" fan fitted underneath. It has about 30% larger surface area over the factory cooler and is fitted with a PWR core. An additional boost gauge port was fitted to the front tank. Some modifications to the scoop seal and retainer were necessary to accommodate the larger cooler.
The fan is connected to a relay that’s controlled by a 50DegC thermal switch from Jaycar, which is mounted onto the intercoolers front mounting bracket. Control power comes from an ignition feed at the wiper motor and power is from the main battery.
I also fitted a ProVent 200 Air/Oil Separator to help control oil build up in the intercooler and inlet system and help reduce the chance of engine failure as a result of oil mixing with EGR gases which forms a thick black grease that has the potential to partially block the intake manifold and throttle body.
