Zd30 common rail overheating

[mudski]

i did not know that, as a general rule on all cars ive always turned the heater on the bleed the cooling system.
figure it cant harm it but good to know.

Yeah the Patrols just divert the hot air from the box rather than using a heater tap to shut off the water supply to the heater core. Been thinking about running a tap somehow as heat does tend to get in via the vents and you really feel it in the summer.
