Radiator Losing Water [Merged]

[chuaed]

paayos mo dapat kaagad iyan, malamang may leak or sira ang radiator cap, whag mo na hintayin lumala pa... hirap niyan pag kumatok ang makina mo... dalhin mo kotse mo kay speedyfix para makita nila ang problema...

everybody, thanks for the replies.

as far as the signs tell, the radiator and water pump are operating normally. no leaks no oil stains steady water flow etc. hoses and caps are looks intact.

except for the lost of water (about 6-8 ounces a day with a 100kms drive even with) and flactuating temp (even with a strong coolnant mix) but not overheating or even nearing 100c. max 95c according to temp gauge.

main suspect is a faulty radiator since it was purchased as a surplus 8mos ago, medyo may kupi na ibang fins. and a distant second is the water pump because its an old car. a very distant third, may crack ang reservoir bottle ko where steam is escaping pero 8 ounces of steam/water, hard to believe

because of budget constraints, out muna radiator or water pump replacement/repair.

as stop gap solution, will try some "stop leaks" chemicals. i have seen 2 kinds, a small yellow bottle of powder, and a liquid made by prestone.

will go for the prestone chemical. i powder stuff looks dangerous and might damage something in the engine, but way way cheaper

Regarding your fluctuating temp. but no overheating: Try to check your manifold thermostat.

pinalitan ko na rad cap, nakabili ako sa DIY SHOP. actually 3 times nako nag overheat. the first one is last December. 2nd hand ko kasi nabili ung '96 vti nung december kaya di ko agad napansin mga dapat ayusin.

the 1st one is nag-clogged ung radiator, pinalinis ko then ok na ulit. the 2nd one was last March, it was a Water Pump problem, pinalitan ko na rin then ok na. then the last one is these past few months.

umabot nako sa red line from 1st to 2nd overheat ko, and di naman nag stall kotse ko kahit napaandar ko pa sya pabalik sa bahay ng almost 10km.

last week pinalinis ko ulit rad and sabi ng naglinis di naman daw gaano madumi. bumili rin ako bago coolant reservoir dahil me konti crack na ung orig na naka install.

then un na nga, nung nakabili nako bago reservoir lagi na lang me natitira tubig dun, pero sa radiator nauubos. pero me konti ako napansin, nung ung luma reservoir pa nakalagay mga 5km pa lang tinatakbo ko tumataas na agad temp, pero nung ung bago na mga 15km bago tumaas ung temp.

i've search this forum about overheating and me nabasa ako about Cylinder head gasket, piston ring and Valve seal na mga dapat palitan pag lagi nago-overheat kahit wala naman ako makita leaks sa ilalim ng kotse. my radiator is a single row surplus.

nag canvass ako the ff: item

cylinder head gasket - 950
1 set piston ring - 1,000+
2 rows evercool - 4,800
upper & lower hose - 580
valve seal di ko pa nai-canvass kasi lately ko lang nabasa dito, and san
ba to located? and mga magkano kaya tong valve seal?
kindly give me also an idea kung mga magkano sisingilin ng mekaniko pag
lahat nito eh papalitan.

i can't go to speedyfix, dito kasi ko sa Dagupan medyo hindi pa pwede ibyahe malayo dahil nga mago-overheat.

thanks for any info.

mahal din pala new radiator,

maybe thermostat problem din sa akin, really need a mchanic for that.

will also buy a new radiator cap narin kahit wala ako kita signs my old one is broken. along with prestone chemicals, a new cap might actually be a good quick solution (may sale sa handyman this weekend, thats where i intend to buy these stuff)

dito lang mahal samin, pero sa manila medyo mura yata, me nabasa ako 4k or less pa yata.

ung thermostat ko at thermoswitch is meron pa, kaya lang napapansin ko kasi ang tagal bago umikot ng fan, kaya for the meantime, nag jumper muna ako sa relay box para laging nakaswitch. pag napaayos ko na lahat saka ko na lang ibalik ung fuse nya.

[puroy]

bumili me ng rad cap sa handy man, 110 lang yung .9. so, far nasa half pa lang yung reading ng temp (city driving). can't wait to try on a long journey.

[mikejohnny]

at last naayos din. dinala ko sa mekaniko kilala ko, i told the problem. nabangit ko pa nga palitan na piston ring, cylinder head gasket, valve seal, if in case un talaga problem. iniwan ko sa kanya the whole day and he found out nga na cylinder head gasket is one of the culprit, then mga turnilyo na mahaba na nag loose tread hindi ko na matandaan ung tamang term nya kasi lack of knowledge ako sa maintenance basta me pina-machine shop kami at umabot ng 1,800, nakalagay dun sa job order is Cylinder Head Resurface, then 1,200 naman ung cylinder head gasket na bakal, asbestos daw kasi ung nakalagay sa car kaya nagka-crack. then sabay change oil na rin, me ibang maliliit na item pa syang binili inabot mga 300. then inayos nya na rin ung sa rad fan kasi minsan hindi daw naga-automatic. then we test drive it 30kms. ayun ok na hindi na tumataas ung temp at di na rin nagbabawas tubig ung rad. i ask him kung palitan na rin piston ring, sabi nya ok pa naman daw kung di naman sira wag muna palitan.

at first i thought ung surplus rad ang problem nun pala something inside ng makina me mga diprensya, sa tagal na din daw kasi ng mga kotse normal lang na me mga wear and tear parts.

so far so good, but i think i should still change rad into 2 rows para sure. 4,800 nga ung evercool na canvass ko. meron kaya 2 rows na surplus pang matic?

[niky]

If you're going in that direction, just buy the new radiator. A surplus may be in worse condtion than your current one or may not be much better. Better safe than sorry.

[typhoon]

Tama, bili ka na lang brand new evercool rad. Cheaper than the one being sold sa casa pero hindi naman pahuhuli quality. Tutal gumastos ka na din so konting piga na lang sa budget para peace of mind ika nga

[mikejohnny]

correct! actually brand new evercool na talaga nasa isip ko, nag-aantay lang additional budget, more than 5k din kasi nagastos ko dun sa pinagawa ko. 4,800 kasi dito ung rad, plus 530 ung upper and lower hose, palitan ko na rin para sure.

[myhondaesi]

Tuwing kelan po ba talaga iyung average para magrefill ing water reservoir?

[speedyfix]

dapat halos hindi ka nagdadagdag ng tubig sa reservoir.

[myhondaesi]

Anu pong pwedeng reason kung bakit nagbabawas ng tubig ang reservoir?

[paolorenzo]

Meron rin ako radiator problem, pero looks like a radiator leak. I'm losing mga 4oz/day. Meron talaga tagas sa radiator area (gitna ng car), and it's leaking pink fluid (Caltex Long Life Coolant). Though puno ang radiator ko pag open, yung reserve ang nauubos. Pero di naman sa reserve ang tulo.

Sir SPEEDYFIX, gumagawa po kayo ng radiator? Gaano katagal po kaya ang trabaho kung radiator leak (assuming puwede i-hinang)? Revo VX200 po ride ko.

[speedyfix]

we don't fix. we normally replace them. it's a better solution in the long run.

[revoGSX]

eto tungkol sa 2000 Revo Diesel ni erpats..

yung dating original radiator nya eh na-overhaul nung 2005 at tumagal ng 1year naman... tapos nung mga year 2006, meron na ulit leak at add lagi ng water mga 2 to 3cups every 2 days, minstan overheat pag nakalimutan nila lagyan ng water.. sinabi ko na palitan na at baka lumala problem, kaso ayaw ni erpats at kuripot hehe

last Monday, march 26,2007, pinalitan namin ng brandnew 3-rows Evercool radiator, kay speedyfix ko na binili at pinakabit hehe... tawag ako ng umaga at nakabit ng hapon.... thanks speedyfix

eto na bago:
-Evercool radiator 3-rows (kita ko na meron na talaga butas yung lumang radiator)
-OEM thermostat from toyota
-Coolant from toyota
-OEM radiator cap (2005 nabili)

hindi na gaano overheat tulad ng dati..

pero may problem pa rin, bigla napupuno yung water reservior nya at minsan mag-overflow pag hinataw tapos tataas na temp gauge to 1/2 to 3/4 tapos balik ulit sa normal.. bago pa namin palitan ng bagong radiator eh minsan ganito na...

ano po dapat ko pa-check sa engine at ano kelangan palitan? cylinder gasket kaya? kaya ba ito ng 1day job?

thanks...

[niky]

Ibig sabihin na-o-overwhelm ang cooling system ninyo tuwing hinahataw.

Given that you have new rad.cap, thermostat and radiator, and are using the proper 50/50 coolant ratio, there could still be a number of things that you could look at:

1. Radiator cap has too low a pressure rating, so it springs early, releasing coolant to the overflow tank. I'm not sure about the Revo, but some manufacturers have different rated caps. I don't think this is the problem, though.

2. Cavitation at water pump, or slipping water pump pulley. At high revs, di siya nakakasabay.

3. May problem ka sa radiator fan? It might not be fast enough anymore, and it might be impeding air flow at speed.

Ride is a Lancer GLXi A/T. 'Ung tubig sa reservoir nababawasan din. On a weekly basis, nagdadagdag ako ng mga 4-8 oz. Daily drive ito ni kumander ng total of 28km a day or 150km a week consumes 4-8oz of water in reservoir.
Ang pinapalitan ko palang ay 'yong radiator cap, pero ganun pa din.
Ayaw ko naman pa palitan 'yong water pump niya hanggat di confirmed na siya nga 'yong problema... one day nakita ko may tulo ng green sa ilalim ng engine bay, so tinignan ko at eto 'yong nakuhanan ko ng pic (the pic is >1 yr-old). E2ng pagbabawas ng tubig sa radiator ay more than a year na. Ano kaya prob?

[recklus]

what part is that? is that well away from the radiator and radiator hoses? if it is away and near the belts i think you have a water pump leak.

i had the same problem, i kept topping up about 500ml every week and kept seeing coolant leak on the garage. i looked under the car and found traces of leak near the compressor belt. when i showed it to my trusted mechanic he had no doubt it was the water pump.
