4d56 overheating w/ A/C on on traffic

[12vdc]

^ Had it replaced, im just observing na lang medyo malamig na panahon pero so far OK na. Another experienced gained, but i hate working on the van- very cramped.

Re thermostat, it has been discussed several times na, one reason kaya sila ang major pollutant sa lansangan.

sana ok na ang car mo. it couldnt be tstat. kasi kung tstat, mag over heat yan while on motion. actually, the function of the tstat is to trap heat in order for the engine to reach the normal operating temp as quick as possible. while others may not agree, our cars will function even better without the tstat as we are in the tropics. pampasadang jeep na halos hindi namamatay ang makina dahil sa palagiang gamit, tinatanggal talaga ang tstat. sobrang init kasi sa atin. regarding sa clutch fan, refilling it with silicon is most practical. mura lang naman yan, around 80 petot yata ang tube. kung talagang nagtitipid, lock mo nalang. sabay sa ikot ng crankshaft. my 2 cents.

kelangan bang i-trato na pampasaherong jeep ang everyday commuter naten?

kasi po sir kung tatanggaling naten t-stat baka sa short trip everyday commuter like a <12 km baka di na umabot lagi sa normal operating temp like a an innova.

kung pang racing racing mode ka na lagi high revving, doon lang po ako mag-agree modifying the t-stat.

i am trying to illustrate the effects of tstat on our engines. as i said, we are in the tropics. kahit walang tstat, we will hit the normal operating temp within 10 minutes. kung may winter sa pinas, we cant definitely reach the normal operating temp even in an hour without it. we will even need to preheat our cars thru electrical plugs in our homes. wala akong innova but by experience, yong delivery van ko dati na L300 na tinanggalan ko ng tstat, idle ng 5 mins, normal operating temp na.

Pag wala kasing tsat, pag nag idle ka ng matagal, may chance na mag overheat cause yung water tuloy tuloy na yung ikot. So iinit siya eventually. Pag may tsat, may time pa na "lumamig" yung tubig.

May coolant ba yung L300 mo? Pag wala, madali talaga ang heat transfer pero kakalawangin naman makina at radiator mo.

You can't be sure na normal temp na since analog ang gauges ng L300. TStat starts to open at 82C and fully opens around 92C. Pag wala ka Tstat, chances are below 82C lang ang temp mo. For your engine to function properly, it must be around 89C(normal idling)-95C(heavy revving), yan ang trabaho ng Tstat maintain that temp.

Mas malamig ang EGT ng non-turbo compared sa CRDI at gasoline so mas matagal painitin. Sa modern efi enignes, babagsak emmission at performance ng engine mo kapag tinaggal ang Tstat. Isa sa sinusukat ng ecu ang engine coolant temp.

Ok lang tanggalin Tstat kung racing or laging WOT, eh hinid naman laging WOT ang Jeepneys at passenger vehicles..

Para din EGR yan, useful lang sa idling speed.

the reason na tinanggal ko ang tstat is, mag over heat pag may tstat. nong tinanggal na namin, di na nga nag over heat. sa obserbasyon ko and i might be wrong with this, ito ay dahil walang bara at tuloy tuloy ang ikot ng tubig. mainit ang 4d56, madali mag over heat at pag nag overheat, warp kaagad ang c.head. kaya kadalasan ng L300 na delivery van, sa alam ko, tinanggalan ng tstat.

the never ending story of thermostat nga ano.....now, answer this. bakit yung pickup ko na turbodiesel (no intercooler) nasolve ko yung "rising temperature on stop and go traffic or stand still" nya nung nilagyan ko ng thermostat? at di na rin nagbabawas ng tubig after mainstall an ko ng thermostat.

in your case,palitin na talaga yung thermostat. the thermostat is a replaceable item. not a repairable or removable item. mas silent pa sa ngayon yung diesel ko kesa nung walang thermostat.

plus, bakit nilagay yang thermostat na yan ng mga nagdisenyo at gumawa ng mga makina? sasakyang pang pilipinas man o hinde.

tanggalin mo thermostat, magoovercool yan on most cases. and what do diesels need to be able to attain good combustion? HEAT is the answer. the thermostat is there to regulate or maintain the operating temperature. be it gas or diesel. mainit lahat ng engines. hindi lang 4d56. some newly designed engines also operate on higher temperatures for greater heat transfer than what we have now.

istorya lang yan ni manong sa kanto. huwag kang magpapaniwala. peace out brader! hehe.....if you want to prolong your fleet, install an mo ng thermostat. sa casa ka na bumili. mas sulit kesa yung murang nabibili sa auto supply.

in my case, may extra thermostat pa nga na nakalagay sa glove box ng pipip ko just in case.

try checking kung "maluwag" na yung ikot ng radiator fan. sa adventure na ginagamit ko, medyo maluwag na kaya they repaired and put new silicon oil.

Sa akin lang parehas, wag i bypass ang thermostat, kasi hindi ma maintain ang operating temperature ng makina. Kung nag ooverheat, hindi kasalanan ng thermostat.
