Thermostat

[gabsports]

mga brader, bago lang po ako d2, ask ko lang po, ok lang po b n walang thermostat ung oto? sabi ng mekaniko ko ok lang dw d2 sa pinas kc mainit naman dw dito satin, honda civic esi '93 oto ko..bumili kc ako ng radiator sa may banawe last monday, sabi sakin nung may ari d ko daw mabibiyahe ng malayo oto ko kc walang thermostat, mabilis dw mag iinit, sabi naman ng mekaniko ko, hindi dw totoo un, ano po b totoo??

[yojstamaria]

AFAIK. it is there for a reason. Alam ko parang valve yan na hindi pinapapadaloy yung tubig pag wala pa sa normal operating temp ang engine mo. nakakabawas to sa engine wear kung mas mabilis papasok sa normal operating temp yung engine mo. Kano lang naman yung thermostat, baka tinatamad lang mechanic mo.

[gabsports]

yan din ang ang exact words na ginamit sakin nung may ari ng binilhan ko bossing, "it is there for a reason". mga magkano b un bossing??

Maghanap ka na ng bagong mekaniko. Obviously, niloloko ka lang or di nila alam ang ginagawa nila. One of the 1st things you check when your car is overheating is the thermostat. If it's not functioning, chances are your fan will not engage.

O di naman kaya ang akala nilang thermostat e yung sa a/c mo?

Ito tinutukoy ni TS: Wax thermostatic element - Wikipedia, the free encyclopedia

Not the aux fan thermostatic switch.

Oj, read my first paragraph. There's a reason why that was written ahead of the last paragraph.

[gabsports]

thermostat n konektado sa radiator bossing, sabi p nya ok lang dw n wala un kc d2 dw sa pinas e mainit naman, mukhang kelang ko n nga maghanap ng bagong mekaniko...salamat

Gabs, yung thermostat ay konektado sa radiator fan. If the temp rises, the thermostat makes contact to kick off the radiator fan to cool off the water to a certain degree. Your water pump is responsible for the circulation of water to cool off the engine.

Pwede mong i-rekta ang radiator fan mo, pero palaging naka-on, chances are the fan will burn out, your car consumes unnecessary electricity, causing your battery to die quicker, on top of that your engine will work hard causing to burn more gasoline, losing some power, and the list just goes on and on.

Ang function kasi po ng thermostat valve ay hindi lang sa pag-init (warm-up) ng engine. Nagre-regulate sya, sa pamamagitan ng pag-transfer of heat and cool. Between engine and radiator, respectively. Kapag mainit na engine mo, and it reach the temperature to set open the thermostat valve. Water heated from the engine block will trasfer to the radiator. Water from the radiator is cool, will go transfer to engine blocks. When the thermostat valve sense the incoming water is cool, going to engine block, at this point, the thermostat valve will close. Water will just recirculate to the engine block. And the heated water that is in the radiator will have time to cool before it will recirculate again to the engine. These process of recirculating the water/coolant from radiator to your engine maintains and regulates the operations of a normal operating engine temperature.

mga sir i have a honda civic 93 nagbyahe ako from comembo to petron c5 south bound to gas up...pinalgyan ko water yung radiator reservoir ko.the temp gauge is good below middle lang..but sabe ng gasoline boy over heat daw ako...di ako naka aircon that time...then na check ko rad fan is not working then mejo inalog or tinaktak ko lang ng unte umikot na mga sir thermostat din po cause nun soory sir newbie lang ako..and sir me maadvice ba kayo na ok na radiator shop or mekaniko ng honda near dito sa makati area or taguig area? thanks in advance mga sir

mga sir i just replaced my radiator.. sabi ng mekaniko ko pansin nya hindi ikot fan pero kapag nka on na aircon ayun ikot na. pansin nya rin matagal ang interval ng ikot ng fan when aircon is on. sabi nya dapat ikot fan kahit off aircon bsta mainit na makina. i may need to replace thermostat and thermostat switch para sure. all along akala ko normal lang na hindi nag on fan kpg patay aircon.. masama pala yun. kaya sabi ng mekaniko ko mag aircon ako para ikot fan until mapalitan ko yung parts na nabanggit ko kanina. what can you say?

Both fans (for radiator & condenser) naman will run, when you turn on your aircon suddenly. When aircon is turn on, every time the compressor kicks in to engaged,both fans activates. It is normal. What you must observe first also is water/coolant in the radiator & reservoir if sufficient in quantity.

thanks po. he said palitan muta thermostat switch and check if kaya na linisin yung thermostat, if hindi na then saka nlng palitan. any idea how much the switch will cost in a honda jazz 2005? thanks!

Bago na rin kasi radiator mo kaya matagal na time interval para umikot both fans, and your condenser as you said bago palit na rin di ba. Dahil new radiator and condenser, madali na lang mag-dissipate ng heat, by free flowing air, kaya siguro pansin mo at ng mekaniko mo, matagal ang time interval ng fans na mag-activate. No temp gauge at red light indicator lang to warn you, if it is overheating. Try mo muna paandarin makina mo without aircon ng idle running kahit isa oras o higit pa hanggang mag-lit ang red light, kapag mag-lit na red light indicator at hindi pa umadar ang radiator fan mo, sige, try checking it all with your trusted mekaniko. Radiator fan FUSE, thermo-switch sensor for radiator fan, thermostat valve and Relay for radiator fan. Determine/diagnose mo muna kung may faulty o wala, para to avoid unnecessary buying of parts that is not really needed to be purchased. [emoji4]

Tama yung diagnosis ng mechanic mo. Nag safe side lang sya na isabay na ang thermostat and the switch

[redone12]

nago lang ako dito
ganyan din sabi sakin esi 94 naman

[Heisenberg]

Correction lang. Ang nagpapaandar sa radiator fan ay yung thermoswitch na nakamount sa thermostat housing and hindi yung thermostat mismo. Kapag mainit na yung coolant, the switch will short to the ground and cause the fan to run until lumamig uli yung dumadaloy na coolant.

Totoo na mabilis pa ding umangat ang init ng makina (operating temp) sa Pilipinas kumpara sa ibang bansa. Kasi sa ibang bansa mahalaga sa kanila ang Heater. Init ng coolant ang dumadaloy sa heater core so mahalaga sa kanila na mabilis maginit ang makina kasi malamig sa kanila (winter). Pero hindi lang mapabilis ang init ang silbi ng thermostat kaya hindi por que nasa Pilipinas tayo ay hindi na to mahalaga.

Ang isa sa mga purpose ng thermostat ay para ma-maintain ang init ng makina. Aside from that, it also regulates the proper flow. Kahit nakabukas ang thermostat, nakaharang pa din ito partially. Iba ang condition pag WALA kang thermostat.

Halimbawang nasa operating temperature na ang makina at nangyari sayo to:

Kapag nasa highway ka at wala kang thermostat, babagsak ang temperature kasi malamig ang coolant sa radiator (nabobomba ng hangin) at tuloy tuloy itong papasok sa engine block. Same thing pag umuulan.

Kapag naman nasa traffic ka at walang nakaharang na thermostat, maaring magoverheat pa din dahil tuloy-tuloy ang daloy bago pa lumamig ang coolant. Imbes na maghintay sa radiator at mapalamig mabuti, iikot ang hindi napalamig na coolant sa mainit sa makina. This gets worse pag sira ang fan. 100% overheat yan.

Keep in mind and tell your mechanic that thermostats are designed to fail in the open position para maiwasan ang overheating caused by a bad thermostat. Mga Engineers ang nagdesign ng cooling system. Yung mga sensors, valves at switches na nasa cooling system lahat yan may silbi para sa efficient performance.

salamat po sa lahat ng inputs.. so far hindi ko pa masyado na drive yung car ng walang aircon kasi bka ako mag overheat kasi hidni ikot fan. mostly the red indicator na nag overheat na yung car ngyari na sya 3x.. mag kakaiba scenario. pinaka last nung nag punta ako batangas on a stormy afternoon habang nsa startoll ako doing 80 to 100 while overtaking. mejo may karga yung jazz.. sana lang may temp indicator para before pa man sya mag overheat eh maitabi muna sa kalsada.. hidni yung huli na ang lahat at nag overheat na.
so far after palitan rad ko never pa nag overheat.. pero palagi ako nag aaircon.
