Radiator / Overheating Problem

[dr. d]

Any of you guys have an idea how long an engine can run without coolant before it overheats? The plastic drain plug of my radiator is broken/leaks and the radiator cannot hold water in longer than 3mins(parang gripo talaga). Sad thing is the plug broke in two such that half of the screw is stuck inside(handle broke off) so i cannot plug the leak...not sure kung aabot pa sa shop mga 20mins away and i dont want to risk overheating the car. Thanks!

if you have a pair of long nose pliers, you might be able to reach for the broken part and screw it out. then you can screw in a brand new drain plug.

Not a mechanic here. Naisip ko lang, kung may butas radiator mo, and your only goal is to bring it Sa talyer, di kaya pwede yung mga pantapal na heat resistant, Yung parang tape na parang foil. Pansamantala lang. Para madala mo sa mekaniko.

Na putulan ako dati ng throttle cable sa old pajero ko. Nasa hiway ako nun. Dinugtong ko muna yung cable using para cord para lang mauwi yung kotse.

Thanks dr d and remzam. Sourced a new plug and used a small flat screwdriver to remove the old plug successfully albeit with great difficulty..ang sikip kasi and mahirap maabot. Nonetheless ok na ulit.

vios 2006 (gen 1.5/1.3 L).

mga bros, temp warning light came up.
even when aux fan is running, i still get the temp warning in dash .
no recent change in the system naman, except for brake pad change about 1.5k km ago and lugnut stud issue the other day.
had it checked in jpwheels yesterday, was told that it was a bad fan, their comment was mahina daw. then went to exalta banawe, they said fan looks OK, as well as the water pump and no leak in system (cap also OK); since they could not identify the problem, they can only recommend to have the radiator checked and/or cleaned.

then i realized, i can check the temp via obd scanner, so i did. from banawe to maybunga pasig, temp never went over 98c (prolly cause it was 5:30pm narin). will update my post later around 12nn.
dati until about 98c (or 100c IIRC) ang inaabot ng coolant temp ko sa obd scanner reading via torque app.
ngayon 90c or lowest * 88c nag blink na ang temp warning sa dashboard. issue just started yesterday. naka toyota long life coolant naman, was replaced just about less than 10k km.

at first i thought it was a bad coolant sensor, but i can read naman via obd scanner that coolant temp is fine, so baka di naman sensor. any ideas kung ano pwede problem?


btw AC works fine even when the temp warning came up.

I'd go with dr.d here.. Change the aux fan.. Minsan kasi ang nangyayari sa Aux may time na kung kailan mo i-check eh gagana yan at may time na biglang titigil o babagal kapag hindi mo ni-check..

sir, maraming possibilities yan, either marumi na at hirap na flow kaya may overheating or pdeng sa water pump din or within sa engine na mismo. critical na part yan so better have it checked para ma identify talaga

You might want to check the thermoswitch. I think this is the one sending the signal when to turn on and off the auxiliary fan.

where is it located bro?

update again ..
AC off ..
confirmed automatic fan turns ON * 95c
but seems too late as by 96c, temp warning light turns ON already.
