  1. ok.. I look into it more. My connector didn't actually "break" I guess some of the connectors loose their ability to clamp down properly over time. I also noticed there was no seal or o ring inside of the connector. But not sure there is supposed to be,...
  2. 2000 Silverado 5.3 Leaking coolant from this connector. It looks like the connector pops on and off? I was trying to remove just the hose clamp and hose.. and the entire connector popped off. What part do I need? Can I just replace the pop on connector? Thank you.
  3. I changed the blender motor and also the temp control motor next to it a few months ago, it fix the HVAC issues but not the gurgle issue
  4. 2000 Silverado, 5.3 - 247K miles. Since I have purchased this truck 6 months ago, it makes a wining sound from underneath when driving. This sound only happens when I let off the gas.. and coasting. First thought is the rear end, or the Tcase. I did change the fluids when I got the truck - rear end fluid looked fine, but I changed to Royal Purple. Tcase barley had any fluid, what fluid did come out was gear oil...not ATF like that case calls for (NP 261 with manual shiftier) Anyway, I refilled with syn ATF....all good. Also replaced the Tcase half recently because it got a hole - pump rub issue. I'm thinking I should refil the Tcase with gear oil? bad idea? I know many folks do this to quiet their Tcase even though the case calls for ATF. Seems like the only risk is the seal to transmission going bad and letting gear oil in the trans. side note - u joints are new. drive shaft has been changed at point (not OEM) truck drives real smooth, no shakes or anything. Truck is just used around the farm... about 4k miles per year. Not a big issue either way.
  5. Also - when you change the shaft, think about changing the steering column bearing at the same time. I assume the 2004 still had this part? Videos online to show you how. I did both on my 2000 silverado, not hard. https://www.amazon.com/Dorman-905-512-Cadillac-Chevrolet-Oldsmobile/dp/B004AI9SQA/ref=pd_bxgy_263_2?_encoding=UTF8&pd_rd_i=B004AI9SQA&pd_rd_r=1SKJQ3FAJ1MSJY15BQSJ&pd_rd_w=b2TUD&pd_rd_wg=ZP7Tm&psc=1&refRID=1SKJQ3FAJ1MSJY15BQSJ
  6. I have the exact same problem with my 2000 siverado. Heat works fine, no leaks and barley hit 200 when cold....just like yours. Mine seems to really gurgle when I accelerate. When idle or cruising it does not. I started looking into this last week... I few things I'm going to try tomorrow. 1. park truck on steep incline with the nose up...so the overfill tank is the highest point. Unscrew cap rev up and hold around 2500 rpm and see if it "burps" out the extra air. 2. Replace the reservoir cap with new OEM one - may be letting in air ? Anyone else that wants to chime in with idea's.. please do so.
  7. Sent you a message about level recommendations from the “consequences of a 1.5” level” article about two years ago. Would appreciate your input. 

  8. I would change your bulbs front and rear....even though they appear to be good.
  9. I already had a hole in my case, so I just replace the case half. Sent from my SM-G930V using Tapatalk
  10. The start/stop tech is not "gimmick"....its goverment making them squeek out every MPG. Just like the awful shifting transmission... awful overall drivability. Front air dams that sit only inches above the pavement, etc That start / stop tech sucks.... I can almost guarantee you that you will have to disable it each time you start up. My wife's car has this, I knew this new truck would get it as well. I assume every vehicle will have it in few more years Sent from my SM-G930V using Tapatalk
  11. 6.2 tuned 0-60

    I like the Airaid Jr..keeps the stock air box. I have a double cab as well with the 6.2. And black bear tune. It flys Sent from my SM-G930V using Tapatalk
  12. 2000 Silverado - Is there a way to program the key fob so when I press the unlock button (one time) both doors will unlock? Right now I have to press the unlock button twice to get both doors to unlock.
  13. ok.. changed out the rear bulb, no help. Noticed the front parking lights wasn't blinking - however, the light was working on the parking light function, but wouldn't blink when I turned on the blinker. Anyway, I changed the bulb, no help. After that I pulled the bulb back out and put back in reversed.. fixed! The issues was either 1. The bulb was in the wrong way ( didn't know these bulbs have reverse polarity? ) 2. I noticed a some corrosion inside of the bulb socket. Maybe when I removed and reversed it got a better connection ? Either way.. it's good now.
  14. I'll replace the bulb and blinker fluid later today and report back.
