  1. Installed a new all aluminum Cold Case radiator in my 06 Sierra 1500 4.8L and I’m having trouble getting up to operating temperature in the normal time frame. I would think this will especially be an issue in the winter, but I’m in Texas so winters are no exactly terrible. Is this something I should be concerned about in the long run not reaching op temp on the majority of my drives? Getting my temp to the 200 degree standard operating temp will take me about 40min of non stop highway driving while the fans are running with the AC on. My temp will climb to the 185-187 thermostat opening fairly quickly 10-15min but as it opens and the fans run, it is just too much cooling for it to ever reach op temp in a decent time. Also if I keep my fans off, and it does reach 200 degrees, in 15-25min, once I turn the fans back on, the temp will drop to 185-187 within 5-10min. I know this radiator was a bit overkill for my stock application, but I wanted an aluminum rad to not worry about leaking issues in the future from plastic rads.
  2. Hello, I have a 1997 Chevy C2500 5.7 and I’m having some cooling issues. I recently did a top off of the fluids and changed the oil, we also replaced the coolant with new 50/50. The overflow tank is always completely empty after being driven for even long periods. After checking the coolant in the radiator we realized that it had gone down too. From what I have checked (and I’ve checked everywhere) there are no leaks. There’s no oil in the coolant or coolant in the oil, the top radiator hose is always hot but the bottom is always cold. I don’t know if that has anything to do with it but I thought it was worth mentioning. When filling the radiator back up with water I also noticed it bubbling while it was going down, is it possible there is an Air pocket? It’s important to note that the truck doesn’t overheat, or should I say it hasn’t yet. Even after taking it on a long road trip. Any reason why my coolant keeps going down and not back into my overflow? Thank you for any help!
  3. Have any of you been able to get GM to cover radiator leaks beyond the b2b warranty? I have 40k on mine and was just informed I have a leak. I noticed they extended the warranty on 14 and 15’s but I’m not seeing any newer models being covered.
  4. Hey guys, i have a 2005 gmc yukon with electric fans. It is the 5.3 and the electric fans will not turn on. I have replaced the coolant temp sensor and the relays and it is still inop. If i send 12v to the fans they will turn on and constant power is getting too the two 4 prong relays my tools will not fit to test the 5 prong. None of the fueses are blown either and relays have resistance to them. It has a slight hickup on startup but not much of one and sadly no they do not work with the ac on the temp will go straight past 210 when parked
  5. Hey all. latest recruit here. Have been in/around all kinda of garages and shops my whole 40+ years. Recently I made a bonehead mistake. While swapping a 1991 engine into my 1986, I mixed up the fan shrouds and tossed the wrong ones. This is irreversible. It got burned up in my trash barrel by mistake. I now have a 1991 shroud that does not fit my 1986. Every diagram I see shows me this metal panel that bolts to my core support. This is incorrect. My radiator is not tall enough for that. My fan shroud had the radiator cushion integrated into it, I am almost certain. How is it that none of the online retailers have this?? Is my truck a weird one? It unbolted like factory equipment, though it was kinda cracked and broken. The bolts were still in place. The radiator is a 4 row radiator with a 29" core. It is not tall enough for a metal top bracket/panel/whatever its called to hold it. Its about 2-3 inches too short. Im ready to beat my face into the cement. Any ideas guys and gals?
  6. Hello. My brother seems to have a bit of a weird problem. He recently swapped his belt driven fans for an electrical ones. He did all the wirings and changed the temp Sensor. Although the AC fan works fine, It seems that the radiator fan turns on instantly when the engine is cold, but when the engine reaches the operating temperature it turns off and stays off. What could cause this? Did he flip a wire somewhere?
  7. Hello all! A few months ago I purchased a 2006 Silverado 2500 with the 6.0 Vortec engine. My coolant is slightly discolored and there seems to be a little scale inside the tank. I would like to backflush the system, but I am not entirely sure how on this truck. My Chiltons manual says to remove the thermostat and reinstall the housing by itself, then hook up a garden hose to the radiator and backflush. 2 chapters later, the same manual says that the thermostat is part of the housing and cannot be removed! Any advice?
  8. about a year ago we had a warm winter. My truck would overheat every once in a while and I would pull on over and let it cool. Here is my question: Are there any plastic parts in the coolant system that could have melted just perfectly to spit out coolant 1) every once in a great while 2) about half a quart all at once when it does 3) when it does spit out coolant, it spits it in such a way to allow it to get none on the belt, but all over the front end stuff thats between the road and the middle of the engine (verticle) and between the engine and the cooling fan (horizontal) I have recently topped it off. Only the reservoir goes empty. It will stay topped for quite some time (months) Sometimes there is no smell of coolant, while other times one can strongly smell it in the cab. One time I had parked the truck and while I was walking away from it I heard the sound of a dog, a really big dog, pissing itself. turned around, saw coolant on the ground, smelled coolant from my truck, and found that it had spat out a mouthful of coolant! That has happened one other time this year. I fear that times when I am on the road and it happens, it burns up before I can find where it is coming from. It is funny that only the res goes empty though. Happy Hannakah!
  9. Hey guys, I've been searching for a while to find a used radiator for my 1982. It has the 6.2 diesel and an auto transmission. Recently I purchased the correct sized radiator without the trans cooler. If I were to get a universal HD trans cooler, would I be able to use this newer radiator and cooler? The cooler comes with relocation lines and everything that's needed. I've never swapped a radiator before but taking the old one out was not as difficult as imagined. Just looking for a conformation that these separate units will work.
  10. Hey guys, just joined, looking for help! I just changed out my water pump (harmonic balancer bolt was a real joy) anyway, I got it all buttoned back up and the bypass pipe was leaking, no biggie, just an O-ring, except when i pulled it off transmission fluid poured out of the top of the water pump. So...now what?? Any advice is greatly appreciated
  11. I have a Silverado 2500 6L WT. I put some green antifreeze in the reservoir and found out that it is bad to mix the green antifreeze with dexcool and thus needed to flush my coolant. I then did a coolant flush with only dexcool to get the green antifreeze out of my truck. All I did was drain the dexcool from the radiator hose, refilled the reservoir with water, ran the water through the engine, and then drained the dexcool from the radiator hose again. All in all, I drained the dexcool from the radiator hose three times (three intervals of flushing water through the engine). I DID NOT remove the drain plug to remove the dexcool from the bottom of the engine block. Did I get all of the green antifreeze out without removing the drain plug or do I need to do another coolant flush?
  12. This grille came off my 2014 Chevy Silverado 1500 LT Texas Edition. I swapped out the chrome grille with a standard black one I bought from ebay. This grille is in perfect condition and can be shipped anywhere in the lower 48 states. I would rather sell locally because it is a big box but I can get shipping quotes for those interested. I am selling this grille for $300, which is $100 less than the same grilles are selling for on eBay so I'm not looking to negotiate on price. I am willing to possibly exchange for different wheels you may have for a Silverado though. If you have any more questions feel free to call or send a text message to me on my cell at 936-828-1985. Have a good day.
