Locate the radiator cap, remove and top off the radiator. If your worried about the closed circulation system you can add water to the over flow jug and it will suction the needed water from there.

Through the surge tank/over flow tank, it retains the water to exchange with the radiator and is marked wioth levels hot and cold.

Is there not a radiator cap on a 1999 silverado? want to flush sysyem but do you refill through resavoir?


If you don't see a cap, you don't have one. If you are flushing in hopes of correcting an overheating problem, be aware that if the radiator is partially obstructed, the flush chems sold today are too mild to actually do much. The better chems were all banned by the epa.
If you are just doing routine maintenance, easiest method of draining is to remove the lower hose at the radiator, let the system drain, put the hose back on, fill with water and any chems you want to use, run it as per instructions, drain again, fill with more water and repeat with water at least twice before draining and filling with new antifreeze.(do all flushing with heater on full heat) Keep the cap off while doing this so you don't build up pressure and be careful draining hot water. Even though they are mild for the job, chems can still irritate your skin so be careful. When filling for the final time, make sure the system is full and the thermostat has opened before closing it up. Always check everything over for leaks.Any other questions? Just ask!!

I recommend this procedure, starting with a cold engine: Remove the radiator cap, remove the thermostat, re-install the thermostat housing, leave the radiator cap off, start engine and idle for not less than fifteen minutes, then turn engine off. Allow engine and radiator to cool completely, then open the petcock at the bottom of the radiator, and drain completely (there will still be some coolant/water in the system).
Remove the thermostat housing again, then remove the old water pump and install a new water pump, replace the thermostat with a new one rated at 195 degrees, and be sure to install it in the proper direction. Fill radiator with water only (you don't want to waste money on antifreeze until you are sure you have heat), leave radiator cap off, start engine and let it come to operating temperature, not less than fifteen minutes. Turn engine off, and let cool compltely. Fill radiator with water only, install radiator cap, and restart vehicle. Let come to operating temperature again, not less than fifteen minutes, turn off. Let cool completely, drain radiator again if your truck got proper heat in cabin, then refill with the proper mixture of water/antifreeze. This sounds like a lot of repetition, but this will flush your entire system, boost your water pressure, and properly regulate your engine temperature. If the problem repeats in your two month window, have the radiator professionally serviced and the heater core will probably have to be replaced.
Always use the proper type and amount of anitfreeze!

Heater not working right in 1999 silverado. Blower works fine,not over heating, blows cool air when idling blows warm air when moving.


First check the coolant level if the engine is hot check the reserve jug on the firewall--if cold before start up remove the radiator cap and check coolant level add as needed. If the thermostat has been removed it needs to re-installed. It is possible that the heater hose(s) is stopped up. After letting it run for a period of time both heater hoses should be hot to the touch if they aren't something is restricting the flow of coolant the system needs to be drained and flushed. I have also see some vehicles form an air lock in the coolant system causing the same thing. It then needs to be (burped). This can be checked/done by removing the radiator cap while the vehicle is idleing and watching the water level in the radiator squeeze the upper radiator hose to see if the water/coolant level rises in the radiator. When you release the hose you may need to add some coolant this forces out the air. Hope one of these things. These are some of the cheapest fixes and if they don't work/help then you need to start looking at the heat control selector.

No Heat and Overheating in 1999 Chevy Silverado


After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

Overheating


Hi,

Based on your description "hard line from thermastat area has a heat wraparound it goes towards firewall", that would appear to be part of the heater system for the inside of the vehicle and would not affect the overheating of the engine.

Most engine overheating could be caused by:
  • insufficient coolant in the radiator or reservoir;
  • defective (stuck) thermostat;
  • too soft radiator hoses (upper/lower);
  • water pump, belt, tensioner;
  • clogged radiator;
  • radiator fan motor, clutch (if has got one), relay.
Additionally, in a large number of vehicles, the radiator fan motor would only work the A/C or heater is ON.

Corrective action would require determining which is the culprit, pls try:
  • remove the thermostat completely out and test drive, see if the overheating comes back, if yes, then it is not the thermostat, if no then the thermostat most likely is stuck closed and would need replacement;
  • on start from a cold engine, remove the radiator cap and pls check if the water flows when the engine is revved. If yes, water pump is working, if not, water pump is defective;
  • in a closed loop cooling system such as in your car, there is a possibility that the radiator hoses might have thinned down or gotten softer. This could be checked by revving the engine while looking over the hoses, there should be apparent sagging or reduction in diameter when the engine is revved. If any, then they are too soft and would need replacement;
  • clogged radiators could be flushed/cleaned by removing the drain plug at the bottom.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
