No enoug heat in a 1999 silverado


The cooling system should be flushed but lets start with the heat,remove both hoses from the heater core, install hose to each end of the core about 3 ft long next take waterhose and and start to flush out start with one side and flush with hose on full water, then move to other side , do this a few times, water flow should be clean and flow good, after that if the heat is still warm replace the thermostat and that should solve the problem. good day.

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 do i change the heater core on my 1999 chevy silverado 1500?


Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

Fog coming from deforst leaving greasy film on window


it sounds like your heater core is leaking. Check to see if your coolant level is low. A radiator pressure test will show a leak. coolant may be dripping down from the heater air box drain hose. Replacement of the heater core is expensive. you can bypass the heater core, to keep you on the road, by looping one of the heater hoses back to the engine....but you will have no heat. Here are a couple of sites for reference;

1999 chevy silverado the heater doesn't put out heat. the engine temp comes up to 190 degrees and the fan works but no heat


Check the valve on the upper heater hose and make sure it moves,if it does then you need to have the heater core flushed.You can do it your self by removeing the heater core hoses from the heater core and runnin water through it with a garden hose but a rad shop can do a better job.If you choose to do it yourself pick up a bottle of rad cleaner first and put it in the rad a few days before you flush it.

No heat !!! just blows cold air. I think it might be the thermostat. Where is that located on a 1999 Silverado? It is the small V8


could be the heater core valve, check the cable that opens and closes the water valve to the heater core.

check also the setting of the temperature level. it could still be set to cold.

wait for a few minutes for the water to heat up on the radiator. you could have tested it after you start the car and the engine is still cold.

tnx 4 using fixya,
