1/4 above normal temperature

[Batang Regla]

Hi yung civic vti ko kahit OFF aircon tataas ng 1/4 above normal temperature.

Hindi naman nagbabawas tubig radiator.

Pwede ba ang cause nito pag mali ang timing at madumi ang servo? or baka pasira na ang relay?

[alwayz_yummy]

1/3 nga normal e.. pero kung lumalagpas sa 1/2 at city drive ka lang... papalitan mo muna thermostat ng cooling system mo, at palinis mo na yang radiator mo... and do replace with coolant-distilled water mix... dont use tap water....

check the fan kung ok pa ang ikot. baka pudpod na ang carbon brush.

1/4 above normal temp which means almost 3/4 of the guage.. kasi yung akin almost 1/2 yung Operating temp ko... check your cooling system.. Radiator and Cap, Water Pump, Termostat and termo Switch, Fan Belt, Hoses...

[sgt_taga]

have the water pump checked. malamang di na yun gumagana kaya kahit puno ang tubig mo, nag-iinit pa rin beyong the normal.

[renzo_d10]

pacheck mo nalang lahat that's related sa cooling system. 1/2 ang normal ko.

[Ry_Tower]

* TS: 1/2 or slightly lower is the normal. Anything above should be taken seriously.

[alwayz_yummy]

di ko masyado nabasa pala.. so 3/4 nga yan.. full check-- radiator general overhaul, thremostat replacement, water pump check, ung fan pag malakas pa ikot--ung hangin na mainit ramdam mo pa hanggang likod ok yan.. and most fans are brushless na!

pagkatapos, replace only with distilled water and coolant...never use tap water.

Pumunta na ako sa talyer. I-schedule ako ng leak test. Buksan daw yung top ng engine check kung warp or may crack cylinder head.

Tinanong ko kung water pump ang sira, sabi kung sira daw water pump dapat diredirecho daw overheat.

Naalala ko kasi nung nagpalit water pump last year eh for Civic 1.5 liter ang nakalagay sa box pero pwede daw sa 1.6 liter. GMB yung brand. Tapos hindi sya all metal. Plastic yung sa may umiikot na part kung saan nakaikot yung timing belt ata.

[alwayz_yummy]

unrelated yun... may thermostat pa ba? kung inalis mo na dapat 1/4 nalang yan kahit katirikan ng araw...pero mas ok kung lagyan mo uli, mas madali nga maatain ng engine ang kanyang working temp. and bleed mo ng maigi ung system pagkatapos... and USE DISTILLED WATER! 60-70 lang naman ang 6-liter pack...manila pure or absolute gamitin mo... wag tap water!


nga pala bago mo pabaklas head ng makina, pa-compression test mo muna, baka di naman talga dun ang prob,e..

Meron pa thermostat.

Kasi kung wala daw leak sa top engine eh next na icheck thermostat. Baka pasira na daw thermostat/thermoswitch ko. Kasi nakakaloko kasi may times na taas temp ng above normal tapos babalik din sa normal.

[phezthie]

kung bumabalik pa sa normal, wag mo muna pabuksan engine... palitan mo muna yung Tstat (mura lang naman and you can DIY) then do some technical tests first... (ie coolant test, compression and leakdown)...

[alwayz_yummy]

thermostat is different sa thremoswitch ha! tinutukoy ko ung nakalagay na parang radiator cap sa isa sa hoses na papunta/pabalik sa radiator, malapit sa makina po to..... un ang tinutukoy ko.. mostly nagcocorode yun dahil sa pagamit ng tap water... pag nagcorrode, di maganda ang bukas...kaya ka nagooverheat..di adequate ate water suplly.. most backyard mechanic, inaalis yun, e nagpalit ka na ng pump, 90% sure, di yan binalik uli.. hanap ka sa banawe ng suitable replacement...

Paano malalaman kung hindi kinabit yung thermostat?

Nagpaleak test pala ako. Meron sila ginamit na air compressor tapos kinabit doon sa apat na butas( kung saan nakakabit yung spark plugs) Yung readings eh sa 1st hole eh may pressure. 2nd, 3rd and 4th wala pressure.

So ang sabi sa akin palit head gasket.

Accurate ba yung ganun test.

[alwayz_yummy]

di ko sure ganung test,e...

pag may thermostat, sa umaga, before 1st start of the day, bukasan mo radiator cap.. then start mo....pag di ka nakakita ng movement, merong thermostat...

[Batang Regla]

Thnaks always yummy.

By the way pag may bubbles sa radiator, blown head gasket daw usually cause? Kasi may bubbles yung sa akin. Tapos nagtatapon ng tubig sa plastic reservoir.

Nag search ako sa yahoo,(posted below) Paki-explain yung BOLD part. Radiator cap or reservoir cap ba ang tinutukoy dito. Gusto ko itry na palitan muna yung cap. Kaso di ba usually ang advice radiator cap ang palitan. Eh dito sa advice na ito resevoir cap.

Tapos yung isa naman, Ano yung ht leads or coil low tension wires?

What causes bubbles in the radiator coolant?[/SIZE]
Answer

In most cases is is blown head gasket. The engine suckes air through the hole in the gasket and sends it to cooling system. You never know how long it gonna last.
Good luck

Can also be caused by a defective pressure relief valve in the coolant reservoir cap. If it is the head gasket, you may also find you can smell combustion gases in the coolant. These won't smell the same as the exhaust gas though as the exhaust has been through the catalytic converter. If changing the cap fails to cure the problem, disconnect and isolate the ht leads or coil low tension wires and remove the pressure cap from the coolant tank. Get someone to turn the engine over on the starter motor while you look into the tank. If you see bubbles emerging in the coolant, it's probably the head gasket.

yung radiator cap, sa ilalim niyan may parang spring, push mo yung yung ilalmi and see kung may puewrsa pa. kung wala na, babalik talaga tubig sa reserve.

If changing the cap fails to cure the problem, disconnect and isolate the ht leads or coil low tension wires and remove the pressure cap from the coolant tank.

ibig sabihin niyan tangalin high tension wires para magcrank lang and hindi tumuloy magstart. tangalin yung radiator cap and crank the engine, kung may bubbles, head gasket na.

Maraming salamat ah.

Yung sa likod ng radiator cap yun pala yung pressure relief valve? So yung reservoir cap na may straw hindi papalitan yun? Check later ko kung may pwersa pa. Tapos sabihin ko sa mechaniko tanggalin yung high tension wires.

Salamat talaga ah sa explanation.

[[archie]]

may iba kasi oto nasa reserve yung pressure relief like ford escape. unlike yung atin sa radiator lang talaga.

yep tangalin lang high tension wires para walang koryente. crank lang to see if the head gasket is blown.

no prob sir.

Ito may nabasa ako. Possibility ba ito.

I have bubbles coming from my radiator tank. What could be the problem? - Yahoo! Answers
I hate overheating problems, I say this because I have had more than my share. These are some things to look at, you didn't say what vehicle you drive, but some are notorious for keeping an air pocket in the engine and not allowing the water to pass through until it "belches" and the water starts flowing, but the problem will happen again because the water will again go out of the block into the radiator causing another bubble, you have to "bleed" the cooling system, let the engine get warm enough to cause the thermostat to open, then fill the radiator, this will cause the thermostat to close again, let it run until the guage shows a drop again then fill some more. The bubbles you see may just be the air in the block coming out when the thermostat opens, just like it could be a gasket, but I'd take 80% odds to Vegas anytime.
One other problem I had that drove me crazy is I changed everything, but when I would accellerate or get on the interstate it would overheat, then cool down at a slower speed, turned out the propeller in the water pump was spinning on the shaft, at slow speed it would keep up, but at speed the prop pushing the water would spin on the prop, took me awhile to find that one as the pump did not leak or make any sort of noise.

Halos same kami problem kasi pag matulin ganyan mangyayari sa akin pero pag hindi lalagpas ng 60kph eh normal temp lang.

Ano pala ibig sabihin at cause ng propeller in the water pump was spinning on the shaft? prop pushing the water would spin on the prop?
