My Lite Ace 96 is suffering the same overheating problem. Can I ask how much will it cost?

Dear Liteace user.
I think one of the root causes of the overheating problem is the water coming out of the radiator neck. You need to replace the neck with a new one or try to repair the neck for proper fitting of the radiator cap. See MegaZip site for ordering the part.

If your engine is 5k, don't use a 4k cylinder head gasket. I experienced that trouble when I used a 4k cylinder gasket for my 5k engine.

When old Toyotas have an overheating problem, it may be solved by a radiator overhaul and pressured water cleaning.
If there's no low compression issue (top overhaul needed to replace with an appropriate gasket), in my case, I replace the radiator cap, OEM if possible. If it's not yet solved, replace the thermostat gadget (OEM too, surplus shops in Banawe have originals).
Finally, please check the radiator neck if it's corroded (mostly due to some cracks leading to easy water evaporation) or if it's made of hard plastic - a Toyota's overlooked mechanism.
Yes, if it's plastic - have a customized replacement made of copper. For P1k (as of 2015), that solved our overheat problems, being a Toyota lover ever since learning to drive.
My street mechanic's in Mindanao Ave., QC, just in front/opposite of the 2nd gate of Veterans Hospital where there's an auto supply, nr Petron... helped me a lot in solving overheat problems. Just look for Orly or Jun, a Bicolano (open everyday except Sundays). They are very supportive.
Finally, an additional small auxiliary fan installed in front of the radiator keeps it cool.

Using coolant has pros & cons.
Coolants sometimes add to "amags", a silvery white algae similar on what you see on the end terminals of car batteries (in the case of batteries, apply grease in the lead area affected). Mineral water only in the radiator is still the best to avoid corrosion, especially in tropical countries like Ph.
Likewise, retain your thermostat gadget. The manufacturer did not devise it to be in the cooling system without a noble purpose; they've got a research department after all.
