2018 low coolant

[swoleymammoth]

Hey everyone,

 

A few months ago I noticed the coolant was low in my 2018 Silverado 1500. I took it to the dealer and they kept it for a couple of days and said they ran pressure tests and couldn't find any leaks. They filled it up and sent me on my way but I'm wondering if they might have missed something? Any reason I might have lost coolant? My truck has 58k miles on it. Thanks!

Mines been at the same level as yours was for like 2 years now.

 

If you ask me that is just the maximum allowed coolant when cold, it's not a bad thing that it's lower than that mark to begin with. Coolant is roughly 50% water so some evaporation over the years could happen.

 

If you don't smell a leak, see it mixing with the oil or see it coming out the tailpipe it's not really a problem.

Never was filled all the way up saving money at factory maybe?

My 2014 had a crack in the plastic along the top of the radiator. I backed into my parking space at work and noticed a little steam coming from under the front edge of the hood. It had been raining so I thought it might have been that. I popped the hood and walked around to the front of the truck and I could smell coolant. Mine was still under warranty so the dealer replaced it.

I had noticed the water being low also. So I added some distilled water to the tank to bring the level back to full. After that was when I saw the steam. That evening when I got home, the level was low in the tank again.
