Ok, I know this is an old post and there are videos showing how to add coolant to the lower part of the tank to resolve this issue. I wanted to clear this up for everyone. Gm knows they have a problem with the sensor in the tank and they should own up to the problem. How ever its not a safety concern for a recall. The gm part number for the tank is 084257137 I paid $93.71 for the tank and I also bought a new cap 084148294 left hand thread. Paid $10.05 for the cap. if the cap is over tightened it may break.

There are a few videos out there where people are filling the lower tank. Please do not do this! The lower tank is the expansion tank and it is designed to fill up when the upper tank gets to high on pressure and fluid. The coolant flows across the top and into the lower tank. When that coolant is needed it will be sucked back up to the top tank. If you fill the lower tank it will spew out all over the tray around the tank and make you think you have a coolant leak. Just top off the top tank Only!

Changing out the tank is a 25 minute Job. Disconnect both negative cables at each battery. Remove the air box and battery in front of the tank. You will have to disconnect the 2 blue connectors and 2 cables from the power distribution block on top of the battery. This will gain you access to the 10mm bolt on the bottom of the Tank. Pull forward and tank will pop out. pinch off 2" hose to the side of the tank and remove clamp and pull hose. There is a 3/4 hose to a nipple on the top of the tank that will need to come off. Rinse coolant off the tray from the hoses being removed from the tank.  Install new tank. Then install hoses. Fill top tank to fill line. Install battery and air box. Connect both battery cables and start the truck. Have someone bring idle up to 2000 rpms for 5 minutes to burp all the air out! Add coolant if needed to the full arrows. Install the cap. Light should be off now.

      3.59 Kroger’s in Montgomery Tx. 20 cents higher than most around here. Very unusual. Saturday they were 3.49.

      Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks.

      Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL.

      Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
