      Ditto that! I got 280k miles in my 99 model, and its telling me low coolent after I drive it longer than a half hour around town. Never had that before. Overflow shows slightly low after a while, I hope its just the cap, or pump and not a cracked fn cyl!

    My 2000 Silverado 5.3 temperature gauge goes up then goes down the over flow hose leaks coolant sometimes and when u add coolant to the reservoir it fills up half way then the rest goes out the overflow hose

    • @jow185
      @jow185 3 года назад

      If it's like my 2003 Avalanche Z71 oh, it doesn't have an overflow. The container that looks like an overflow is part of the cooling system itself. When the engine is hot that plastic container is actually pressurized. It acts as an extension to the radiator. If it's like mine you'll notice there is no cap on the radiator. The only place to add antifreeze and coolant is in the plastic container itself.

My patience is long gone. I do like helping others especially younger guys in the shop who want to learn. I believe that on todays cars you need a little old school as well as technology to be successful at repairing them. The younger generation wants to diagnose problems with scan tools and scopes and have no respect for old school. When I pointed out recently that the misfire our young apprentice could not find was a huge carbon track on a spark plug porcelain the first thing he said was that it didn't show on any of the test equipment. LoL.

Luckily that solved the issue when the truck kept loosing some coolant.

      Best to just go and buy a cap to have even if you don't quite need it! Rent a pressure tester and test the system as well as the cap, likely the cap could be a part of, if not the whole issue. Water pumps are fairly easy to replace, but new engine sounds like a disaster.

      Jasper does see this a lot.They have a youtube channel and have a video on it.This is with every core they receive.Seen this with a 2005 GMC Sierra so far,the heads were junk and the customer was losing coolant.Pulled the valve covers,sludged up with an orange goo.

    what's the normal operating temperature for a 2000 Chevy Silverado 1500 2wd? my temperature gauge is reading a tick below 210 is there any way to get that a little bit lower I've changed temperature sensor, 195* thermostat, coolant flush (50/50 orange, new radiator, hoses, oil change, water pump it's not leaking at all it's not burning antifreeze at all new knocker sensors, new gaskets and it's still reading a tick below 210 any help thanks

      @johnpetty8277 6 лет назад

      The old trick of using a lower temp thermostat does not apply well to computer controlled engines. The computer expects something around 210 F. If it is lower, like 195 F, it will assume it has not warmed up completely and it will not run right.

      The transfer station takes 5GA a day for free. I know they make some interesting stop leak formulas but I haven't tried any other than the alumaseal powder. IM sure some folks on here will suggest all kinds of super duper stuff. Just stay away from the black goopy bars-leak garbage. That's stuff causes serious problems. I would put a couple tubes of alumaseal from NAPA and try that

      @ThecardoctorTV  8 лет назад +1

      +Joe Tiller I could see if it had some stop leak in the coolant or clumps of stuff that clog up the cracks but probably not common. I like using Alumaseal stop leak. It's the powder stuff in the small tube. The black oily liquid type stop leak is bad.

    How can you check the radiator fluid easily in this engine? I see the reservoir but no radiator caps. Also those chevy jerks up in the canada factory shipped my truck with a stripped spark plug hole in the cylinder!

    • @jow185
      @jow185 3 года назад

      But everybody keeps calling the reservoir is technically the same thing as the top of the radiator. What you see in there tells you if the radiator is full. If you feel that and start the truck it will immediately go down when the water pump starts to turn. Once the radiator is completely full and the thermostat is open send you Phillip to the right level for hot. When you start the vehicle it should not go down.

    Hi Car Doctor. I have a 03 Chevy Avalanche with a 5.3l Vortec. In April, 2016 the motor blew due to a lifter seating. I had a Reman Jasper motor put in. I also paid extra for a kit that replaced water pump, fuel pump, belts, hoses etc. Oh and i also had the driver side intake manifold replaced. The problem is I still am using antifreeze with no sign of leakage on the outside. Any ideas?

    • @ThecardoctorTV
      @ThecardoctorTV  7 лет назад

      The most common source of coolant loss on your vehicle is leaking water pump. Look under the front of the vehicle along the front of the engine for any signs of coolant. It runs down the front and off the sides of the oil pan.

    Engine swap for a bad head? I guess when your spending other folks money. Obviously the engine is fine, clean the thing out, R&R the heads. Sounds like if it were to come in with a bad battery you would suggest replacement of the entire vehicle. Just my opinion though. More power to ya, if you convinced the customer bro replace the entire engine for a head problem.
