What's your coolant temperature?

[yapoy86]

Ok pa kaya water pump ko? Kinunan ko ng video while the engine is at operating temp with the rad cap open.

looks ok naman... no bubbles or traces of oil? nag palit ka na ba ng radiator? yung OEM? sabay mo na din palitan yung rad cap

Yup new radiator and coolant mix of 50/50. No bubbles din and oil. So head gasket leak is not in the equation i guess. Worried lang kasi ako bakit always 100c above yung coolant temp ko according sa obd port. But temp gauge sa dash is below 1/2.

Update: heater mode is not hot. It’s cold. Baka may air pocket or stuck thermostat? When i rev the engine it gets hot but then goes cold again at idle. Thermostat or water pump?

all the cars i have owned, have their normal temp needles at "just slightly below the middle mark".
by my reckoning, that is normal.

I observed this to be true, for newer vehicles. I just don't know why with "Fiera" and "owners" that the gauge stays about 1/3 from zero. The same is true with our CR-V 98. Now I'm thinking, there could be something that is not normal that I thought all the while is normal.

thats one of the advantage of having a heater... it helps if the radiator fan is dead. but its cold if there is a water pump failure or air pocket (unlikely if it was bled correctly)

Hmm, nakita mo ba yung video? Ok pa yung water pump? Baka airpocket lang talaga to kasi nagpalit ng radiator eh. Paano ba ibleed ng maigi? I already followed guides I read on the internet re: bleed/burping rads and I think nagawa ko na ng tama. Di ko nacheck nalang is ang thermostat.

Update: nag 115c ako. Temp gauge started to rise.

Top hose is very very hot. It’s like touching an iron.

But the bottom hose, its just warm!

Does this mean a stuck thermostat? Help me rule out the problem. Monday ko pa mapashop if thermostat.

When that happened to my Corolla (AE92) years ago where the engine temp rises when the engine was revved constantly (3k rpm), it was the thermostat.

dapat ni-replace mo na din thermostat mo kasi baka na stuck close yan gawa nung debris ng old radiator..

Papacheck ko na to after holy week. Kaya pala bumigay na yung old rad ko dahil di na kaya ang init at pressure. Naawa ako sa sasakyan. Sana nga thermostat lang at hindi water pump!

[suysuy]

Update:

replaced thermostat
replaced radiator cap


still overheating. check water pump tomorrow. I'm almost certain it's the water pump already. Might be the impeller. wala na atang naiwang impeller. Puros rust kasi yung thermostat pagtanggal. Wala na, it's really the waterpump. Hay masakit to sa bulsa.

i bought this OBD2 gadget. able to set overtemp alarm. etc

Old water pump.



New water pump.



More often than not, water pump talaga ang salarin sa overheating. Ended up replacing the radiator (well due narin naman talaga for replacement) thermostat and radiator cap. Water pump pala ang sira. Pero ok lang at least my cooling system is top notch again.

GMB water pump 2,800 bili ko. Not bad. Magandang brand na raw ito.

Partly negligence ko rin. When the radiator was convered to brass tank, hindi ko na siya na refill ng coolant. Distilled water nalang. It took 2 years for the impeller to disintegrate.

Kaya lesson learned, pure distilled water can cause accelerated degradation of your water pump.

distilled water doesnt have corrosion inhibitors. two kinds of metals will cause bad corrosion..

Diba distilled water is as good as coolant?
Di nga lang ganon ka effective sa cooling pero hindi sya mag foform ng rust.

lower boiling point - coolant
rust protection- coolant

distilled is only for temporary use.

Ubos yung impeller.. usually pinapalitan ang water pump sa timing belt change.. gmb is a good brand.. pinalitan mo na din sana ng oem gasket..

After a month or on next maintenance, drain mo ulit coolant mo to make sure na malinis ang cooling system.. medyo rusty na based in your old water pump

Water dissipates heat better. Coolant(glycol based) is mixed to raise the solution's boiling point, raise water's PH, push corrosion back....& those in temperate regions, this will serve as anti-freeze.
Periodic coolant swaps are required as it will degrade & turn acidic over time. Check the PH level of coolant annually. It should be maintained between 9.5-10. If it goes below 8, swap ASAP. Your engine, water pump, radiator, heater core will thank you for it.
For those who are going for a complete engine overhaul, take this opportunity to go Evans Waterless Coolant & stop worrying about periodic coolant swaps. Evans CANNOT be mixed w/ water. System should ideally be free of water upon switching.
Evans coolant stops engine problems due to water
