Engine problem 1KZ-TE
1995 Toyota 4Runner 4 cyl Four Wheel Drive Manual 163000 km
I have bought a Japanese import with 1KZ-TE Engine and use it in Botswana at average 1000 m Altitude.
When driving steady on more than 100km/h the engine starts overheating.
I have changed the radiator from 3 core to 4 core to increase coolant capacity which seems to have an adverse effect, also removed the thermostat to increase water flow.
The car has modifications like ARB winch bar, spots and modified bash plate but no engine modifications.
This is a great car but I am disappointed with the problem, specifically in high ambient temperatures (30 deg C+).
I consider to install a safari snorkel to reduce warm air intake from engine compartment, but otherwise I am not sure how to overcome this issue.
Some guys claim to change the turbo to South African Spec's but this is costly and not guaranteed to succeed.
Anybody has some experience how to overcome this problem?
Thanks for your time answering - appreciated
