If there is one - it should be located in the top of thermostat housing
Where is the coolant bleeder valve located on a 2003 nissan maxima 3.5
not all cars have bleeder valves; it may be located on the intake manifold or the pipe neck that the radiator hose goes into
open bleeder on engine by the upper hose outlet.
The thermostat should have a air bleed valve built in and the air bleed valve should be facing straight up.
On a 2003 Pontiac Grand Am, the coolant bleeder valve is located on the engine near the thermostat housing. It typically appears as a small screw or bolt. To bleed the cooling system, you would loosen this valve while the engine is running, allowing trapped air to escape until a steady stream of coolant flows out. Ensure the engine is at operating temperature for effective bleeding.
After you have completed work on the cooling system and you begin to replace the coolant, open the bleeder a couple turns. As you pour coolant into the reservoir air trapped will escape out the bleeder. As soon as you see coolant come out of the bleeder close the bleeder valve and continue to add coolant to the reservoir until you have reached the full mark. Replace cap on reservoir. Allow vehicle to run through a drive cycle and cool down. Top off reservoir to full mark if necessary.
I don't know where specifically they would be (if there are any at all...), but on most of the engines I have worked on that have had them, they were in the engine block somewhere, with the intended purpose of a drain, not an air bleed. I don't think many modern cars (if any at all) have bleeder screws for coolant.
You can't bleed it any other way, you have to bleed it through the bleeder valve to get all the air out.
bleed it the same way u would bleed the brakes the bleeder is on the driver side of the trans on the bell housing
If it has bleeder valves then use them to bleed the system, if not, jack up the front of the vehicle as high as possible. Remove the radiator cap and start the engine. Add coolant to keep the system full. This will allow air to escape.
The "bleeder screws" that come to mind are:Brake bleed - found at each wheel caliper / wheel cylinderEngine coolant - NOT found on a Windstar engine. Cooling system bleeding/burping is basically through just running the engine with the coolant reservoir cap off.
well, if there are two bleeders at the same level, the one that works will suffice, at a lower empty rate. If there is no second bleeder, use a small diameter siphon, or remove the lower hose from the radiator.
