The radiator drain is on the right lower corner of the radiator (passenger)
You can use a wide flat blade screwdriver to unscrew it.
Is is held in by a piece of plastic so you don't have to worry about losing it when draining. just loosen it and leave it there.

Lay under front of car and look under the radiator. The radiator support/header panel should have a hole in it look up in hole the petcock should be hiding in there. DO NOT LAY UNDER THE CAR WITHOUT THE E_BRAKE ON, please.

Hi there,

They are always at the bottom of the radiator. Some are on the side facing the engine, others face straight down. Both types are much more easily detected from beneath the vehicle

Best regards

Get a large drain pan and make sure the engine is not hot.On the lower part of the radiator you will find the drain petcock.It could be on the left or right side.Usually left.Remove the drain petcock and the coolant will come out.It could get messy.When you install the new one make sure and put thread sealer on it so it won`t leak.Teflon tape or Teflon paste will work just fine.Hope this helps.Good luck.

Lower radiator hose


None. Open the petcock on the radiator to drain the cooling system into a drain pan. Close the petcock, remove the clamps that hold the lower radiator hose to the radiator and the water pump. Remove the hose, install the new one, install the clamps, fill the cooling system, and you're done. With the radiator cap off, run the vehicle with the heat on until the engine gets up to operating temperature, allowing the thermostat to open, to allow you to be able to completely fill the system. Install the cap and you are done.

2002 Chevy Astro- how do I drain the Radiator?


If the engine is cold the fastest way is just to put a big drain pan under the bottom radiator hose and remove it. If the engine is hot there is a petcock on the bottom of the radiator it will be on the side under the hood, either side usually opposite the lower radiator hose.

Yes it is normal just no hot air


1. When setting the temperature to MAX, blower level to FULL and outside air Vent CLOSED, no hot air comes out after 2-5 minutes?
If YES, when did you last flushed your radiator and is it full?
2. if more than 5 years ago, flush radiator system, instructions are usually in Owners manual. Use a bottle of Radiator cleaner, run egine hot for about 10-15 minutes, carefully open petcock in bottom of radiator to flush out radiator, WARNING, careful as flushed coolant would be boiling hot. As sson petcock is open and water start to flow out, carefully open radiator cap to enhance flushing flow. Use garden hose to fill radiator while flushing until water coming out from petcock is cold and clear.
Once clear, start engine, turn heter full and blower full blast and keep hose in radiator flowing full, leave petcock open until clear water flows out again. Once clear waters comes out, turn off engine,turn off garden hose and let water drain empty radiator. Once it stops flowing out, close petcock snug and put radiator cap on, pull off radiator coolant catch bottle, clean bottle for any debris and dirt. Drain any water, leave bottle empty and put it back onto its place.
3. Fill radiator with 1 gallon (4L) of concentrated coolant, top up radiator until full, fill catch bottle with concentrated coolant, start engine and keep it overflowing until no bubbles comes out and the radiator is fully hot. Once it is flowing good, close and connect everything. Drive with it and keep catch bottle filled as necessarry.
Good luck. Give as vote and good comment if this advise solve youor problem. Thank you.

Place a drain pan under the petcock.
Slowly turn the petcock CCW
Be careful to avoid contact with the flow if the car is hot
Open the petcock several turns until the flow is constant.
Remove the radiator cap to allow air into the radiator
once flow has stopped, close the petcock.

What do i have to remove to replace the heater core in my 1991 chevy s10 with a 2.8 v6


Draining the Cooling System
  • Park the vehicle on a level surface. If the engine has been running allow it to cool completely.
  • Drain the cooling system. Remove the radiator cap from the radiator. Locate the petcock valve on the lower corner of the radiator. Place a waste oil collection pan underneath the petcock valve and turn it counterclockwise to open. Allow the cooling system to drain completely.
  • Label and remove the heater hoses from the heater core. The heater hoses will connect to the heater core in the engine bay, on the firewall, on the passenger side of the vehicle. Use either the Phillips or the flat-blade screwdriver to loosen the hose clamps that secure the hoses to the heater core. Then pull the hoses off the heater core.
Removing the Heater Core
  • Remove the heater core cover. Move to inside the passenger compartment. Locate the heater case. It will be bolted to the firewall, below the dash on the passenger side of the vehicle. Use an appropriate sized socket or wrench to remove the five screws that connect the heater core cover to the heater case, and remove the cover.
  • Remove the steel straps that secure the heater core to the heater case. Unscrew the four screws that connect the steel straps to the heater case using a socket or wrench and remove the straps.
  • Remove the heater core by pulling it out of the heater case.
Installing the Heater Core
  • Place the new heater core into position inside the heater case. Be sure to carefully guide the inlet and outlet tubes through the holes in the firewall.
  • Reinstall the heater core retaining straps, by reinstalling the four screws that secure them.
  • Place the heater core cover into position over the heater case and reinstall the five screws that secure it.

Refilling the Cooling System
  • Reconnect the heater hoses to the heater core. Slide the hoses onto the inlet and outlet fittings that extend through the firewall, and tighten the hose clamps.
  • Close the petcock valve on the lower corner of the radiator by turning it clockwise.
  • Refill the radiator with a 50/50 mix of antifreeze and water.
  • Reinstall the radiator cap onto the radiator.
  • Run the engine and visually inspect for leaks.
Good luck and take your time.

Im trying to change the antifreeze but it has only one cap on the plastic and not on the raditor would that be a prob when change


Best way to change the antifreeze is to open the petcock at the bottom of the radiator to drain the antifreeze/coolant. Once completely drained close the petcock and refill. Only other way would be to get a flush kit which involves cutting a heater hose, inserting a T and running a garden hose through the system with the radiator open at the bottom through the petcock while the motor is running.
Hope this answers your question. Good luck!

How do I change the lower radiator hose


Cooling System
Ensure that the engine is completely cool prior to starting this service.
1. Remove the recovery tank or radiator cap.
2. Raise and support the vehicle.
3. Place a drain pan of sufficient capacity under the radiator and open the petcock (drain) on the radiator.
è Plastic petcocks easily bind. Before opening a plastic radiator petcock, spray it with some penetrating lubricant.
4. Drain the cooling system completely.
5. Close the petcock.
6. Remove the drain pan.
7. Lower the vehicle.
8. Determine the capacity of the cooling system, then property refill the system with a 50/50 mixture of fresh coolant and distilled water.
9. Leave the recovery tank or radiator cap off to aid in bleeding the system.
10. Start the engine and allow it to idle until the thermostat opens (the upper radiator hose will become hot). The coolant level should go down, this is normal as the system bleeds the air pockets out of the system.
11. Refill the system with coolant to the proper level.
12. Turn the engine OFF and check for leaks.
