Radiator / Overheating Problem

[ninjababez]

last september bumili ako brake shoes dyan kay toyorama tapos pinakabit sa tambay mech dun and while he's doing his thing tinanong ko sya kung magkano labor pag replace ng water pump sabi nya 1.8K-2K up, depende pa minsan daw kasi madami pang kelangang baklasin bago mabaklas yung water pump

Looking back at post 144, how reliable was your temperature reading? Otherwise, have fun chasing your tail

As per your writeup, the engine is obviously not overheating. It is the overheat warning light that you are concerned with. Depending where your car was manufactured, the THW or CTS or the coolant temperature sensor feeds this information to the ECM and is forwarded to the body control computer or BCM and is given off as a signal to the IPC or instrument panel cluster.
Your car might have inter-computer communication problem or your CTS is giving wrong signals. Have your car scanned for communication or U codes. What you are doing is way too far from the possible cause. You might even have IPC problems. Be very careful of mickey mouse trouble code readers and dongles.

bro ano yun ICS? CTS?

thanks

CTS is coolant temperature sensor, Toyota calls it water temperature sensor hence the THW input terminal to the ECM


I CS I don't know I did not mention that

By communication errors, it means your control modules within the car may not be communicating.
Your car might have obd 2 ISO 9141 communication protocol.

will have the water pump replace later bro
previous owner replaced the orig 50k km ago with a surplus, so i think OK lang to have it replaced narin; if OK condition pa, atleast may backup ako. already sourced water pump aisin brand * 950 php via toyocars.
after nito thermoswitch naman, but ill try to clean it thoroughly muna before buying since brandnew orig is at 3.1k and was told this rarely breaks naman daw baka masayang pera.
last na yung aux fan since it is still functioning, and no mechanic (5 of them) wanted to replace it.

if the thermo$witch ha$ no moving part$ outside, cleaning it$ outside$ won't amount to much.
good luck, $ir.
we await the blow by blow.
