kakapalit ko lang ng coolant sensor and thermostat kahapon.
symptoms that i've encountered:

a) ang lakas magbawas ng coolant sa radiator, pero hindi nagagalaw ang coolant sa reservoir.
b) hard starting. usually, it takes me around 4 tries to start the engine, specially during mornings.
c) higher than usual FC. my normal FC is around 12 kpl... bumaba ng 9 kpl.
d) rough engine.
e) overheat

the thermostat controls that flow of coolant papasok ng engine. pag mainit na, bubukas ang thermostat allowing coolant to flow in... pag lumamig, sarado yung thermostat and it allows the engine to warm to optimal operating temperature.

on the coolant, i use prestone pre-mixed.
