Sorry for the thread hijack. Def bring that in, that is a lot of coolant disappearing. They may give you special consideration as the vehicle is just off warranty by mileage but short years in service. Problem is if they hit you with a 4K repair bill you dont want to pay you will have the service record in the system if you later wanted to be naughty and "flip" the car on vroomba or carnivore.I have a 2019 Nissan Altima 2.5L with 65k miles on the odo. I've owned the car since new. In the last 3 months, I've gone through 1.5 gallons of Nissan 50/50 coolant topping off the reservoir.
Open to feedbacks and opinions.
powertrain is still under warranty.
Did the consumption start or get worse when the radiator or coolant reservoir cap was replaced?
Nissan have it reversed compared to many other cars, the cap with the spring goes on the reservoir not the radiator and conversely the radiator takes a non spring cap.
Doing it the other way around will lead to small coolant leaks that add up.
It would be going either into the exhaust after the combustion process or into the intake before the combustion process.Trying to grasp this leaking EGR cooler situation. Where is the coolant loss going? Was it an external leak or was is going into the intake manifold or exhaust system? It's gotta be one of the three. The last two would be bad.
And why Civic Si or VW Jetta Turbo or why Kia Forte GT ? Same kind of stuff.I'm a fan of Nissan, but reading Sentra Turbo reads like a Why Bother, lmao...
Wow-I would be buying a lottery ticket, that’s beyond lucky! I had a company van that leaked coolant from day one (‘18 Transit 250 3.7), after 5 or 6 trips to multiple worthless Ford dealers I just gave up & put ginger root stop leak tablets in it. Which stopped all the leaks & promptly plugged the plate & stack transmission cooler… I was glad to see that one go at ~120K miles!I have an update on the coolant consumption problem. My local Nissan dealership was unable to determine the root cause of the coolant consumption. The dealership reached out to Nissan USA and according to the service manager, Nissan USA immediately responded and asked the dealership to replace the EGR cooler. Apparently Nissan USA has seen multiple EGR coolers fail on 2019+ Nissan Altimas that has a direct correlation to coolant consumption. The EGR cooler has radiator like fins inside and if the fins are broken, coolant is unable to flow through the fins and evaporate due to hot exhaust gas.
The good news is the EGR cooler is covered under California emissions warranty, 7 years, 70k miles, whichever comes first!
Water/coolant going into the intake will help keep the top end clean. Water injection cleans carbon deposits quite well. 😄Trying to grasp this leaking EGR cooler situation.
