Weird temp readings on Lancer CVT MX 2004

[batang_raon14]

Guys, need some opinions. I drove my Lancer from 9AM in the morning yesterday till 1AM today. I went from Paranaque to Cubao, Cubao to Dasmarinas, Dasmarinas to Paranaque, Paranaque to Angono, Rizal, from Angono to San Simon, Pampanga, and finally from San Simon, Pampanga, back to Paranaque.

The car only got less than 5 mins. engine turn-off in most of the stops except when I stopped over at Angono (took 30 mins.).

Before leaving Angono, I checked at the tires, body parts, and coolant level. Level is still full in the coolant so I thought things would go well for the remaining trips.

So I then left from Angono to San Simon, but upon arriving at EDSA North the car's temperature gauge went from 1/2 to 3/4... I then slowly went to the rightmost lane, turned my hazards, opened the hood, and checked what could be wrong.. can't find anything (ang dilim pa) except the level of the coolant decreased a bit. So I placed the key to ON in the ignition to check, and the temperature is back to normal (1/2). The temperature went fine for a long while until I'm back en route to Paranaque from San Simon. Bandang Bicutan SLEX na ko nung bigla na namang tumaas ung temp and maya-maya bumalik rin to normal.

So, what could be causing this? Some additional info that may help:

*Car is due for PMS
*Car never got a time to rest from 9am till 1am of more than an hour
*Scent of oil in coming from aircon vents everytime there's a sudden press on the accelerator.

the oil scent is definitely not good. have the car checked asap...

did your aircon still blow out cool air even at 3/4 temp reading?

Sir malamig pa rin naman ung aircon kahit 3/4 ung temp reading.

hmmm...i was thinking na probably kasi it was just running the whole day. then again, naalala ko yung ae92 GL namin that my folks would bring to the province, nakakaya ng 8 hour drive yung typically 12 hour drive, short stopover lang twice, di naman nagooverheat or anything close to it.

then again, this definitely calls for a trip to the casa

[batang_raon14]

tnx sir. guess deretso akong casa bukas. hehe. salamat po uli.

[nugundam93]

anyway, i do hope the other tsikoteers give their inputs later.

hindi nga normal yan. yung lancer ko, when we went to subic, di nagbabago temperature readings. nasa 1/2 lang sya (which is the normal temp), and the aircon is in full blast.

di kaya sa thermostat yan?

Guys, sorry for the delayed update.

Sent the car to the casa since Tuesday pa (day after coding), and kahapon lang narelease ung findings ng casa (kesyo raw maraming tinanggal et al) so kahapon lang din ako nanotify regarding the situation.

Most of your guesses were right, UNFORTUNATELY. Why? Eto report saken:

1x replace thermostat
1x replace fuel gasket
1x refill all oil levels (perhaps dahil 40t PMS 'to)
1x replace radiator (di ko narinig mabuti) fan
check ECU programming
check tubings

at marami pang iba... total na singil saken 43K!!! Upon asking kung ba't kelangan palitan ung thermostat (dahil nga masyado pang maaga), sabi kesyo raw aftermarket nakalagay (hello?! Sa kanila ko lang dinadala ang sasakyan ko!), ung fan nung tinanong ko kung baka naman nakarekta, sagot saken di raw nila alam... tsk. Sabi ko ung necessary lang muna sa PMS ang gawin. Pagkapullout ko ng unit sa Tuesday baka patignan ko sa ibang shop for 2nd opinion. Hay...
