    5.3 overheats when going up mountains. Any ideas?

    The fans come on when the Ac is on or when it gets to a certain temp. It's set up with a relay. The fans do not come on as soon as I turn the car on. I also thought about getting a different thermostat. When overheating, the system did act like there was an air pocket, sort of like burping the...

    5.3 overheats when going up mountains. Any ideas?

    Here are some photos of my setup. One thing I was concerned about, was the T that’s shown in the photos. Not sure if it’s allowing the right flow. Again, I’m only overheating going up super steep inclines. The only thing is, we didn’t overheat going over Monarch Pass in Colorado, but I think I...

    COMPLETE LS SWAP MPG

    I’ll take some photos of my setup, but again, it’s only happening when going up mountains. My only downfall is that I don’t have an rpm gauge setup. Maybe I should order one of those obd2 scanners before I head out again. I’ll use third gear, find a new overflow tank that’s not melted and...

    COMPLETE LS SWAP MPG

    Sorry, didn’t see those questions. 235 I feel like you’re telling on me man. Did it piss you off that much that I started a new thread on a new topic so others can see? I’m just trying to have a smoother ride back home. I’m not expecting others on the forum to see what one user and I are...

    5.3 overheats when going up mountains. Any ideas?

    I’m not 100% sure. It’s pretty much stock right out of a 2005 Silverado.

    COMPLETE LS SWAP MPG

    I have replaced all fluids, except for rear axle oil. I’m getting 20, at 85 mph with steep mountain passes. How much better mpg would do you think I would get if I change the rear gear oil?? Don’t pick at me man. I’m far from a bozo. Also, I don’t think it would cause it to overheat but I’m...

    COMPLETE LS SWAP MPG

    I had a really nice 88 Camaro that was manual and hated it in the city. I think I would’ve like it more if there weren’t so many stop signs and lights.

    COMPLETE LS SWAP MPG

    I checked 6 months ago. I believe Well, this is assuming the previous owners never replaced the lubricant, then yes. Do you think this could cause the overheating?

    5.3 overheats when going up mountains. Any ideas?

    Brand new cap but I can go pressure test it once more. How important is the overflow tank? The threads melted when it overheated on the way over here. Also, I’m running 16lbs, that sound about right? I’ll drain and mix with 50/50 before heading out.

    5.3 overheats when going up mountains. Any ideas?

    I’ll lose almost 1.5 gallons of coolant when going up mountains. I have a 5.3, 4l60e with stock v6 gears. I think 273s or something like that. Anyways, any ideas? Could it be that my rear end is pulling my motor abdctrans down? I have a 1k treck back home and I’d like to make it.

    A/c with Ls Swap

    My advice, don’t use the stock AC condenser, pull a newer condenser with the lines and get the lines to fit onto your compressor. Keep everything capped until you’re ready to install. I’m currently running a complete ac system. With installing everything myself, I was still at a grand. If I had...

    A/C & heater control vacuum line info

    I set mine up today, you MUST have vacuum from the engine going to the gray and purple lines. Use a T setup and tie the lines together. You should get air from vents.

    Buick GNx sending unit and pump

    But, I think you can get away with the stock tank with upgraded pump and sending unit. My mechanic that builds LS swaps also confirmed, but wanted to be safe on long distance trips. If you do the swap, order without fuel tank neck and order YOUR fuel neck and install.

    Buick GNx sending unit and pump

    I’m using a fuel tank from a Monte, about the same as your GI, and just drove it across the country. I’m using an AC Delco pump tho.
