Current status: Worried.
A few years ago found maybe lowest mile sonata (YF) 2.4L in the country with about 1900 total miles or around 300 miles a year for the first 7 years of it life... It was the typical grandma owned/operated... go to church on Sunday vehicle and parked in garage for the rest of the week... She had oil changes done about every 10 months or around 260-300 total miles like clock work. This was documented on Carfax also.
At the time of purchase the coolant in the overflow reservoir was about 90% to the full mark, but figured it would be a good idea to have some on hand and to top it off to full. I called the Hyundai dealer and asked for coolant after giving them the vin. "Sure come in a pick it up" it was over $30 from what I remember for the gallon... and at the time I did not think anything of it because I thought I was just paying an OEM price....
Fast forward a couple years and 75,000 or so miles and more specifically the last couple (3ish) oil changes the Sonata is BLOWING through coolant and oil.. The oil REEKS of fuel, and turns pitch black within 700-1000 miles of a OC and I have to add a qt by the 2500 mark... As I am again topping off the coolant getting more concerned every time I check the oil and coolant, I use the rest of the original gallon of coolant that I bought for the sonata 75K miles ago.. I look at the bottle as I am putting the cap on and to my HORROR it is 100% straight concentrated coolant NOT 50-50.... I froze.. After removing the radiator cap, only 2 drips of coolant came off of the cap because the fluid is so "Thick". It also looks 100% pure coolant and a super dark green, not the light green like the kias..
I have some serious concerns at the moment because of the oil usage, and the coolant the burns off.
I am hoping that the oil is burning off because the engine is running way to hot, and there is not actually engine damage...
I am also hoping the coolant is burning off way faster also because it is now maybe a 80-20 or higher mix not a 50-50.
The dealer parts are closed at the moment, but this upcoming week I plan on flushing the coolant system and putting in pre mix 50-50 oem coolant plus change the oil.. Should I also replace the T-stat if it has been running so hot? What do you think my odds are I escaped major engine damage? The temp gauge never went above normal, but we all know they are mostly dummy gauges anyway....
