The heater core is in the dash.The complete dash has to be removed and the steering wheel taken out to get to the heater case.The a/c system has to be evacuated and the coolant partially drained.Not a job for the diy.This is about an 8 to 10 hour job.There is a heater and a/c plenum that has to come out then you take that apart to get to the heater core or the a/c evaporator.Hope this helps.Good luck.

Location of heater water control valve for 1999 Chevrolet Silverado 5.3 liter 2 wheel drive P.U.


The right side hose coming from heater core runs into a connector. There is a hose parallel to this connector. At the end is what your looking for. If your wanting to replace this cause your heater doesnt work id recommend flushing your heater core first. My heat didnt work at all flushed it yesturday and works like a charm.

How to change heater core in a 2000 Chevrolet Silverado Heater core is leaking inside the truck


I believe on this model 1500/2500 gas w/ac that you have to first evacuate the a/c system and then remove the HVAC module [fancy wording for the entire heater box assembly] then remove the core from it once you have the assembly out of the cab. I also believe its about a 6 - 7 hour job and not one you'd want to try on your own unless you have quite a bit of mechanical experience behind you as it's not an easy one to do. It's also very easy to damage the new core when reinstalling the assembly back in the cab which will truly wreck your day if that happens!

Strong antifreeze smell when running the heater in 99 silverado, can't see a leak, strong smell, is heater core bad


Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Removing the heater core from 2000 silverado


When I replaced the heater core on my 95 Suburban, I seem to remember having to disconnect the A/C lines on the firewall for the evaporator. There were also several nuts to remove on the engine firewall side from studs on the heater box that pass thru the firewall. It is definately a lot of work.

Good luck.

Heater doesn,t blow hot


Have you checked your coolant? if coolant is low it can cause an air pocket in heater core and it wont pass out until rpm's increase by the extra flow of water pump. if it is full then might wanna try removing heater hoses and back flushing heater core with water might have a little trash in it restricting flow.
