COMMON ISSUES
Overheating
Common causes for Prado overheating is an old radiator cap (not holding pressure), radiator itself (blocked or not holding pressure - replace every 200,000km/10 years), thermostat malfunctioning, and in some cases the viscous coupling fan engaging/disengaging incorrectly..
Buying advice / common failing and worn items are:
* Front upper/lower ball joints: Not expensive to replace but if left to fail, quite catastrophic and dangerous.
* All other ball joints: tie rod ends, sway bar links. Cheap/easy to replace.
* Most steering racks are worn by now and so are the reconditioned ones. Brand new Toyota is around $2000 or Chinese made $300-1000.
* Radiator, typical aluminium/plastic type has limited life, expect 10yr/200,000
* The v6 needs timing belt service every 150,000.
* When replacing front lower control arm bushings, be prepared to replace the cam adjustment components as well. Depends on the vehicles life - evidence of rust will suggest it'll be difficult to remove them - in some cases cutting is required!
