ang normal is walang mababawas na coolant. pero kung nagbabawas ng 1 small cup per week, malakas na leak yan. kung 1 small cup per year or kahit every 6 months, tolerable pa siguro.

kahit may leak sa system, walang overheating na mangyayari basta di maubusan ng coolant ang radiator mo. kaya check coolant level always and top up when needed.

Estimate lang naman yung one small cup per week, minsan two weeks na lumilipas parang wala pang nabawas. Dunno kung ano ang history ng water pump neto. '92 model pala baka dahil sa tanda na rin.

Ganun rin ang rate ng water loss ng Hilux namen kasi sa probinsya eh

okay lang yan. importante lagi na lang check ang coolant level para wag mag-overheat.

isa sa longest na nabasa ko sa forum is 4 years na car, 1-cm coolant level lang ang nabawas. very good condition sigurado ang cooling system nun.

If you are losing coolant there are several things you need to check:

1. Hoses/clamps
2. Radiator cap & Filler neck
3. Reservoir cap
4. Drain plug seal.

A perfectly sealed radiator loop will not loose coolant.

Try running the engine and open the radiator cap. If there's a lot of bubbling then you may need to check your cylinder head.
