IF you replace all the coolant, you use that to get the air out of the system..

Bleeder valve where is it

Are we speaking of brakes or coolant system?
If its brakes the bleeder valve is located on the the caliper usually has a rubber cover over it. On most it's either a 8 or 10 millimeter socket to brake it loose.
And if your speaking of the bleeder valve for the coolant system it's located on top of the thermostat housing. Hope this helps you out.

I cant find where the radiator cap is on my 97 jetta glx to refill the radiator the reservoir is full just need to fill the radiator but dont know where???

Your overflow cap is your radiator cap. What you may want to do is check the thermostat housing for a bleeder. Just in case the thermostat housing is where your upper radiator hose mets your engine. On top of it may be a bleeder valve. Let the car come up to normal temp and open the valve slightly until antifreeze comes out then tighten it up.

5.0L and 5.8L Engines
  1. Drain the cooling system to a level below the thermostat.
  1. Disconnect the upper radiator hose and the bypass hose from the thermostat housing.
  2. To gain access to the thermostat housing, either mark the location of the distributor, loosen the hold-down clamp and rotate the distributor, or remove the distributor cap and rotor.
  3. Remove the thermostat housing retaining bolts and the housing and gasket.
  4. Remove the thermostat from the housing.

Fig. 7: Thermostat installation-5.0L and 5.8L engines

To install:

  1. Clean the gasket mating surfaces.
  2. Position a new gasket on the intake manifold.
  3. Install the thermostat in the housing, rotating slightly to lock the thermostat in place on the flats cast into the housing. Install the housing on the manifold and tighten the bolts to 12-18 ft. lbs. (16-24 Nm).
If the thermostat has a bleeder valve, the thermostat should be positioned with the bleeder valve at the 12 o'clock position as viewed from the front of the engine.
  1. Install the distributor cap and rotor, or reposition the distributor for correct ignition timing, as necessary. Tighten the hold-down bolt to 18-26 ft. lbs. (24-35 Nm).
  2. Connect the bypass hose and the upper radiator hose to the thermostat housing.
  3. Fill the cooling system
  4. Check for leaks.

Hope helps (remember to rate and comment this)

Replaced water pump and thermostat still over heats - 96 oldsmobile

you have a air pocket in your system you will need to get the air out of the line. if your thermostat housing has a bleeder valve on it start the car let it warm up to operating temps then crack the bleeder valve until it runs steady with coolant if you do not have a bleeder take the radiator cap off start the engine and let it run until you see the coolant flow through the radiator also do a pressure test on your coolant system to ensure that you dont have any leaks any where. or possibly even a bad head.

Hello, towards the bottom of the radiator is a drain valve, either the lower right or left side. There may also be a bleeder valve on the thermostat housing. Hope this is helpful

I replace the radeator and the car still run hot changed cap, hoses and checked for thermarstste and couldn't find it

Follow the top radiator hose back to where it connects to the engine.
The part with the two bolts in it that the hose connects to is the thermostat housing.
You may have to remove the hose in order to remove the housing.
When you have removed the housing, note the position of the thermostat before you remove it.
When installing, use new gasket, etc.
(you might be able to get away with not removing the radiator hose, but it is recommended)
Be prepared for a bit of spillage when you remove the housing.

Does my cooling system have a air bleeder valve? I have filed my system with antifreeze, changed my water pump, thermostat and still it heats up quickly.

According to my data base it has one, but it doesn't give the location. The ones I've seen are located on the thermostat housing or on the engine close to it and they look like a brake bleeder valve.
