    Nangyari na sa akin ito with my '97 Civic Vti about 2-3 years ago. In my case, the problem was plain and simple leaking radiator cap. I found that the rubber seal of the radiator cap was already brittle and does not snugly fit the radiator lip kaya nauubos yung tubig in the form of steam kaya walang evidence ng leak. Nung na-replace na, wala na yung problem.

    What you can do temporarily is put a plastic, double folded, over the radiator lip then put in place the radiator cap to snugly fit. This may temporarily solve your problem. Kung hindi na nag-o-overheat, then radiator cap nga ang problem. Replace it immediately. If this does not solve your problem, pa-check mo na buong radiator system mo. Usually it is the rubber and plastic parts of the system that wears down over time because of the heat exposure.

    Just be extra careful in performing the suggestion above. Coz the Radiator cap functions like a pressure releif device. The plastic could break and block the passage of steam to the water reservoir. A new cap will only cost you around 150 pesos give or take, so if your cap is old or wornout, better just get a new one. Ensure you get the right size and pressure rating for your vehicle. just my suggestion.

    Yeah, I agree DonT. He should be extra careful with the radiator cap especially if the temperature gauge is in the critical level (red or near-red level). I have seen several people nalapnos ang mga balat because of exposure to superheated steam in attempt to relieve the temperature of their radiators. Mura nga lang pala ang radiator cap. Bili ka na lang ng bago bengkok. Kung walang pagbabago, seek professional help.

    Merong leak yan, imposibleng wala. San naman mapupunta yung tubig?
    I also used to own a '96 Civic VTi, ganyan na ganyan ang simtomas, mag-ooverheat tapos tuwing umaga ubos ang tubig. PinaLavramon ko, wala naman masyadong duming nakuha tapos di nasolve yung problema. One night, may nakalimutan ako sa loob nung auto kaya I went back to it 30 minutes after I shut off the engine. Ayun, natsambahan ko kung nasan yung leak! Narinig ko may parang sumisirit sa likod nung grill (sssssstt!) The culprit? Yung radiator top may hairline crack sa may base, leaking water.

    Ang orig na radiator niyang Civic mo is made by Denso, so you can have it repaired sa mga Denso service centers. It cost me P2,500 for the radiator top & gasket, inclusive of labor when I had it done in 2005. Some independent radiator shops would offer to replace the radiator top with a copper one or to replace the whole radiator with a local one but I decided to keep the orig radiator. It never overheated nor leaked water again until I sold the Civic last year.;)

    * ooba99 ---> Yup you are right...better be safe than sorry.

    *Automahn --> Same thing happened also to my brother's vti. In his case, irrepairable ang verdict..so he bought a new one.

    agree... check the peripherals muna before opening up the engine... simple stuff like a visual inspection should be able to tell you if may leak or not though.

    *Bengkok

    Here's base on my experience. I have also 96 VTI Matic.

    1st overheat:

    When I got the car December of 2005, everything else is fine kasi city driving lang ako. The Radiator then is 2 rows. One time we went to nearby province (Jan.06), running around 40km na, napansin ko unti-unti tumataas temp. I pulled over and check ko rad, nabawasan tubig. So what I did, lagay lang ulit and drove back home. Pinahinga ko then check ko ulit while idle, tumaas ulit temp pero no leak sa ilalim ibig sabihin no problem sa water pump. No oil sa rad and no white smoke sa tambutso ibig sabihin o.k. ang cylinder head gasket. Pinalinis ko rad and we found out madumi na palang mabuti and me maliit na butas, so nilinis at tinakpan ulit ung butas, bought new rad cap it was 0.9. And everything is ok again.



    2nd overheat:

    It was March 2006 morning, we went to distant town, almost 80kms ride with no problem. Nung pauwi na kami that evening we're running almost 60k when I noticed tumaas ulit temp. Pinahinga ko, lagay tubig, wala pa ulit 10km natakbo namin, tumataas ulit temp. So ganun ulit ginawa ko, paulit-ulit lang, pahinga-lagay-pahinga-lagay, talagang less than 10km overheat na ulit. Pag uwi bahay pinag-masdan ko kinabukasan while idle without aircon, in less that 10mins. taas na ulit temp and noticed sa ilalim me tumutulo, dinala ko sa talyer and found out sira na ung Water Pump. So we replaced it and everything is working very fine again. The Rad is still 2 Rows.



    3rd and Final Overheat

    It was May 2006. Tag-ulan nun, I'm always having hard starting my car. Pag nag-start naman, parang kumakadyot ang takbo, sometimes bumababa idle, namamatay makina and unti-unti tumataas ang temp. Napansin ko din ung Reservoir is kumukulo ung tubig pag mainit na makina, then me lumalabas pa na puting usok sa tambutso ang lakas parang sa mga jeep. Then one night pauwi nako sa bahay after office, ayaw mas start ng car, kumakadyot lang. since matic hindi naman pwede itulak. So iniwan ko sa office yung car, the following morning dinala ko Mekaniko at pinatignan ko ung car. Tinanggal nya ung mga spark plug at pina start sakin. Pag start ko me parang bumulwak na tubig dun sa lagayan ng spark plug. So and conclusion nya, Busted Cylinder Head Gasket. Dinala namin sa shop nya and inayos nya for 2 days.

    1,200 pa bili ko nung cylinder head gasket that time, ung metal not asbestos. Nag change oil kami, and me pina-machine shop sya. Di ko sure yung terms nila pero parang "Resurface" ung ginawa sa machine shop, cost me 850 i think sa machine shop. Then changed Radiator from 2 rows into Single Row na surplus.

    So since that last overheat till now wala na ung problem ko. Lahat nung nangyaring overheat naka aircon ako that time.

    So here's my 3 things to consider when having overheat.

    1.) Kung walang tumutulo sa ilalim walang problem sa Water Pump, linis lang sa radiator and check kung me leaks, plus change rad cap.

    2.) Kung me tumutulo sa ilalim, and sobra bilis pag-taas ng temp, water pump ang problem

    3.) Pag kumukulo ung reservoir, mabilis ding tumaas temp with or without aircon, plus me usok na puti sa tambutso, hard starting... for sure sa makina or cylinder head gasket ang problem.


    Better have different opinion sa mga mekaniko. Dun sa 3rd thing, ung kumukulong reservoir lang alam na agad ng mga makaniko na me tama na makina. Ung isang pinag-tanungan ko gusto palit na daw makina dahil for sure busted na daw, aabutin 30k plus ang gastos. Ung isang gumawa since me ESI sya, kabisado nya sakit mga civic, so in-advise nya madadaan sa palit cylinder head gasket and some machine shop lang, which it really did. Basta wag lang daw umabot sa 3rd time palit gasket, kasi pag ganun, me tama na daw talaga makina.


    Pasensya na mahaba post ko, pero i think mas-detailed mas maganda. I hope this helps.

    Informative post.

    Pero ano kailangan gawin para maiwasan masira cylinder head gasket?

    Pwede ba hindi sira ang cylinder gasket pero sira yung makina?

    Ok yang mechaniko mo ah. Sa iba kasi popular car repair mahilig sa palit agad.

    - I think iwasan lang talaga mag-overheat sasakyan kaya make sure malinis lagi rad. pero kung talagang luma na car, just in my case 10yrs. old na, minsan talagang bibigay na lang siguro. so be prepared.

    Pwede ba hindi sira ang cylinder gasket pero sira yung makina?

    - Pwede ata to, kasi ung tinatawag nila "kumatok" ung makina, eh sira na ung engine block nila, pero not necesarily ung cylinder gasket. Or pwede ding both, pls. clarify lang dun sa mas nakakaalam.

    Ok yang mechaniko mo ah. Sa iba kasi popular car repair mahilig sa palit agad.

    - yup, kasi ayaw na nila tumagal pa sa pagre-repair, at least mas malaki kikitain nila sa palit makina dahil kung sila na ang maghahanap makina para sayo, papatong pa sila dun plus yung labor na pagkataas-taas. Mostly ginagawa ng malalaking talyer to na madaming client para iwas istorbo. ung pinagdalhan ko kasi maliit na talyer lang pero at least kahit paano me mga customer at me suggestions lagi

    To check if you have leaks, have a competent shop or mechanic perform a pressure test on your cooling system. This is done by connecting a device to your radiator through the cap and pressurizing it. If the pressure holds, seen through the pressure guage, then you dont have a leak.

    Dont know if radiator shops do this. Had my car checked by Autotechnika at the fort last summer, no charge.
