    Radiator swap from a ‘99 Express

    I have here with me a radiator from a 1999 Express & it looks nearly identical to the one in my truck. The dimensions match & so do all the holes & what not. I was wondering if anyone here knew something that maybe I didn’t before I tried to install it into my truck. It’s in much better shape...

    Cooling System Issues?

    Hi everyone, I just had the radiator in my '93 L19 Suburban replaced by a local shop, and as I've been daily driving it the past couple days (abt 4.5 mi, mostly uphill) , I noticed the truck now consistently runs at 140-160. Before I had the radiator replaced, it would always run at around...

    How does the cooling system work?

    First time owning a heavier duty truck, just curious to learn how the coolant/radiator system works. The coolant tank was damn near bone dry but the radiator has coolant and the gauge isn't showing any overheating. so obviously this isn't like a car, right where you just monitor the coolant...

    Radiator Upgrade for 5.7L

    I recently bought a 1994 GMC C1500 with a 5.7L, and it needs a new radiator (previous owner epoxied a crack, and it seems to be holding up OK for now, but I'm too paranoid to let it go). I've seen posts about upgrading to a 454SS radiator. I know there's been several discussions about this, but...

    Needing help ASAP

    My radiator is stripped where the trans cooler line goes on at the bottom. It’s a 92 k2500 with a. 5.0 and 700R4. There’s a much larger threaded fitting around the smaller internal compression one. Is there any way to get that to adapt to my trans line? I think the trans line is a 3/8 line with...

    Radiator Upgrade

    I have a 92 K2500 with a 5.0. I am replacing the radiator and saw some talks about upgrading from a single core to a dual core radiator. Is that something I can drop in or easily modify to fit? Is it also worth doing? I have a 28 inch core, but it is a single core. What vehicle setup would have...

    Oil Cooler as Trans Cooler?

    Replacing my radiator and I see the options for the ones with engine oil coolers. Would it be worthwhile to get this style of radiator, even though my truck does not have a setup for an engine oil cooler, and plumb it as a secondary trans cooler?

    Radiator Size

    I am trying to figure out what radiator I likely have without having access to the truck at the moment. It is a 92 K2500 5.0 with a 700R4. It is a stock truck with the stock radiator. I pulled a fan shroud from a 94 suburban once and it was larger than the one that is currently on my truck. I am...

    I have my transmission pulled to get it rebuilt. While it is out I am wondering what maintenance things I should do while it is out? I have a 92 K2500 with a 5.0. I plan on replacing the seals on my transfer case (potentially rebuilding it as my 4wd doesn’t work and I’m not sure why), replacing...

    Coolant drain and fill

    Just got my truck and not sure of the service history. It has 75,000 miles but definitely a farm truck. I was wondering what a coolant drain and fill would look like.

    No radiator cap on 1996 6.5L. How to drain and how to fill

    Probably a dumb question. I read that this must be a fully pressurized cooling system since there is no radiator cap on either side, only at the overflow reservoir. What would be the procedure to refill with coolant? I see a bleeder valve at the top of the radiator hose. Do I turn out the...
