Q: Parts change interval

asked by on August 09, 2017

Hi

In early 2015, i changed below parts

Coolant ,Waterpump ,Thermostat ,Radiator hoses ,Timing belt , ATF fully synthetic and Tyres in 2014

After i replaced /changed above parts , i only driven for 27,000 km. Now is August 2017. When should i change above parts again? Is it time based or mileage based?

As for engine oil, i maintain using Royal Purple HPS fully synthetic

Another question, liquid to liquid vs liquid to air oil cooler, which one is better in hot climate?

I ditch away liquid to liquid oil coolers, for engine oil i use Setrab 19 rows with fan,.For ATF cooler i use Setrab 16 rows. For engine oil cooler it's fine. Coolant before radiator is 88 celcius, and after radiator 50 celcius. Im worry about ATF temperature, especially when stuck in long traffic jam. The position of ATF cooler is facing air, in front of aircon condenser, so when stuck in jam it get help from sucking radiator fan....i little
