1993 Toyota LiteAce LX review from Philippines

Overheating.

Not-so-cool air-con.

Frequent timing adjustments.

Lite Aces are very sturdy and reliable vans. My father bought this van when we were still kids and what a van it was then. It was very stylish and comfortable. 10 years after, he gave me this van as my first "car". I love this van and I intend to keep it until I can buy my own car and have my own family. But then, I usually have these problems with overheating, poor air-con (which they say is because of the overheating problem), and frequent timing adjustment. I had the aircon condenser fixed under the middle part of the van so as not to burden the main engine compartment with its heat, I also installed another auxillary fan (4 all in all), had the alternator changed to accommodate the additional electrical load, used good quality engine oil, had the tubes and hoses changed, I drain the radiator often like once every month, bought good quality radiator caps, and put coolant... but I still experience overheating when there is traffic. The van can take 30 minutes in traffic, but longer than that, the temperature starts to heat up. I usually turn off the aircon for 5-10 minutes to let it cool down.

I hope some of you guys can help me with this problem. I read that removing the thermostat helps. Give me an idea. Thanks!
