What's your coolant temperature?

**suysuy** · March 29th, 2018 10:28 PM

So i just replaced my radiator. I bought this obd reader from Lazada. I am just curious since my coolant temperature is 96c-110c. Temp gauge never touches middle. It's slightly below the middle mark.

Car: Sorento 2009 2.5 EX VGT

Should I be worried? Coolant is 50/50 mix. I checked other vehicles they stay at 88c-92c.

there could be several reasons.
1. thermostat is not opening
2. water pump is almost ready to go
3. radiator fan is ready to go

That range is on the high side. Generally ideal to be at sub-low 90s. Check the high & low speed fan functions aside from those mentioned by Stock E. Bleed coolant properly, too.

hyundai din sasakyan ko. I changed the waterpump and thermostat na. thermostat is around 1k, water pump is around 5k. radiator fan im not sure of the price.

Are lower temp thermostats available for Hyundais, sir?

OE thermostats are generally designed to open late for temperate regions to hasten engine & cabin heating on cold months. Cold starts & delayed heating are unhealthy for the engine. But...we're in the tropics w/ terrible traffic that cancel that concern. Having lower temp thermostats could help a bit in our conditions. Those units w/ resistor controlled multi-speed fans can also be tweaked to run on high all the time when the ECU calls for low. The engine, & the people inside the car will appreciate these tropic traffic cooling mods....just sharing some unsolicited proven unconventional cheats.[emoji4]

A bit of caution here:

Most thermostats starts opening at around mid-70-80°C and are completely open by around 90°C. Most engines' optimum operating temp ranges between 95-105°C. There's no need to replace the thermostat unless it is defective. Using a replacement part that opens at a colder range will not solve a cooling system fault that is caused by something else. Besides, making this mod will more likely than not prolong warm up times for that engine.

Also, tweaking the radiator fans to always spin at high speeds (even if the ECU is requesting low) will likely shorten their life. You could end up with dead radiator fans in the middle of a trip..... and then you're really in a mess.
