it seems your car's thermostat still works. that's good. that's how it should be.
about "mabilis uminit"... do you mean, mabilis lang ma-abot ang normal working temperature? or do you mean, nag-overheat? if the former, then that's normal again.

Thank you po sa quick response sir dr. d, regarding po sa umiinit ang makina basta mainit lang po sya and ung host from radiator to makina kapag hinawakan mainit din po sya, dko lang po alam if normal lang un kasi ngayon lang po ako nagkasasakyan. Then regarding po sa radiator fan and aircon fan sir sabay sila sisindi kapag switch-on ko aircon ko, maya-maya mamatay tapos sisindi ulit ganon po talaga un? Kung connected po radiator fan sa aircon edi kung hindi po ako mag-aircon sir hindi po sya mag-function kahit mainit na po makina? Or dapat aandar parin automatic ung fan kahit off aircon ko kapag uminit na po makina? Pasensya na po sa mga tanong ko sir.

To TS, pasensya nadin po nakisali ako sa thread mo sir, medyo related po kasi ung mga gusto ko malaman sa kotse ung post mo po sir. Thanks.

Sa aking opinyon, basta gumagana yung automatic rad fan, walang problema yan.
Yung additional load ng aircon sa makina ay magpapataas ng temperature. kung ayos ang thermostat mo, automatic naman mag rerespond dapat ang radiator fan.

Ok lang sir. Tanung ko lang, sabay na namamatay automatic ung AC and Rad fan mo?

regarding naman sa init, I think normal ung uminit ung mga hose. Dun dumadaan ung tubig galling makina papuntang radiator and paikot ulit.

Sir, ung AC fan ba nag-aautomatic din? namamatay kapag medyo malamig ung makina then sisindi ulit? Or continues lang? ung nakasetup sakin kasi ngayon continuous lang, mamamatay lang kung patay na din ung aircon. Di ko alam kung un ung original setup e. Civic Lxi 97 ung sakin.

Thank you sir Mark sa additional input nyo sir and allowing me po na makapag-post sa thread mo. Regarding sa aircon fan and radiator fan sir sabay sila namamatay then sumisindi ulit, dko pa gaano namonitor ung fan ng aircon bago lang po kasi ung kotse sakin pero ung radiator fan confirmed kona na namamatay then sisindi ulit kapag naka-on ang aircon ko sir. Ang inaalala ko lang sir since iikot lang sila kapag naka-sindi ang aircon pano kaya kapag hindi po ako nag-aircon, dahil walang fan baka mag-overheat makina. Tulong naman po sa mga expert dyan. Ano po ang normal behavior dapat ng aircon and radiator fan? Thanks

a/c off-engine cool----------------both fans off

a/c on-engine cool----------------both fans at low speed

a/c on-engine hot-----------------both fans at full speed

a/c off- engine hot----------------condenser fan off, radiator fan at full speed

Ok Sir, so always on ung AC fan kapag naka-ON ung AC. Di siya mamatay.

Thank you sir Jick, base sa illustration ibig sabihin po kahit na parang ang set-up is mag-on ung Aircon Fan and Radiator Fan kapag sumindi palang ang aircon ko, kusa padin iikot ang radiator fan kapag uminit na po ang makina kahit naka-OFF ang aircon sir? Tama po ba pagkaka-intindi ko? Thanks

oo tama intindi mo

nangyayari din yung kahit mainit na makina at naka-on ang aircon, parehong mag-auto-off ang dalawang fan kasi malamig na ang evaporator (ng aircon, nag auto-off ang compressor/condensr fan) at medyo bumaba na rin init ng coolant (nag-auto-off ang thermo switch ng rad fan) ... pero ilang seconds lang nangyayari ito, kasi mabilis din bumalik yung init ng coolant at mag-auto-on uli rad fan
