2. your auxiliary fans are sub-optimal. they may spin, but not fast enough... the air sucked in is not enough. or they may not spin at all.
3. your radiator is clogged, making cooling sub-optimal.
4. you have a crack in your engine block, or a blown head gasket.
5. etc.

have fun troubleshooting.
this is the best solution. i suggest you buy toyota superlong life coolant yung premix at color red (wala naman iba alam ko) you need at least 4 liters or 2 bottles (2 liters per bottle at 300 pesos each). it helps me trouble shoot my 96 civic for leaks. kasi once it dries, it leaves a residue and red mark kung saan lumalabas ang leak.

i end up, replacing my radiator (LVC in Banawe is once of the cheapest source of radiator) afterwards, sa hoses pala problema. until unti unti kong narerepair ang hoses, then isa isa namang nagbibigayan ang hoses ko.

ohh, by the way after the lower radiator hose, napansin namin na durog na ang thermostat ng civic so i repalced it.

afterwards, ayun wala ng leak sa radiator reservoir naman lumalabas tubig and end up having a bad head gasket lang. better than full overhaul. now my engine is in pristine condition.
