How can I bleed a air pocket on a 95 Toyota Camry do they have a bleeder valve if so where is it located


Air pocket in the cooling system i'm assuming?
Remove radiator cap when the engine has cooled down (verify by collapsing the upper radiator hose to make sure there is no pressure remaining) start the vehicle, turn your climate control to high fan, hottest temp. Add coolant to the radiator as needed. You should have good heat coming out of defrost when the cooling system is successfully bled out.

98 JEEP CHEROKEE, TEMPERATURE GAUGE JUMPS AROUND TO HOT- BACK TO NORMAL, TO HOT WHILE DRIVING- JUST REPLACED THE RADIATOR. COULD THIS BE A THERMOSTAT PROBLEM?


did u bleed the air from the cooling system? if not u need to do that, u have air pockets getting around the thermostat, to bleed raise the front up as high as poss with a floor jack, fill the radiator and coolant recovery tank as full as poss, then run engine until it reaches normal temp, then shut it down and run cold water over the radiator,this will draw the coolant out and the system will bleed the air out.

My 96 Roadmaster tends to run warm when stitting at idle in heavy traffic plus the air from the heater turns cold. I replaced the thermostat but it didn't solve anything. Both fans are working. This only...


Sounds like you may have a air pocket in your cooling system. With the engine at normal operating temp,remove the radiator cap and run the car at 1750-2000 rpms keep topping off the cooling system until it won't take anymore and replace the cap before you let it return to idle.Also make sure your overflow bottle is at the hot level.If that doesn't work try doing the same steps with the front of the car raised.

Car ran hot ...low on coolant..added to reservoir...car not running hot now but level in reservoir keeps going down...have added twice more to max line...no leak under car temp normal


Bleed your cooling system. You have a air pockets in your system. Don't forget to run your heater full blast when doing so. Usually help to unplug your heater hose and flush out the heater core then work on getting it filled and getting all the air out of your system.

Do I need to bleed the system after replacing the radiator cap?


Definitely recommended - Process is fairly simple, let the vehicle idle and/or reach normal operating temperature - turn the"bleed screw" slightly open and note as the air bubbles escapes from the screw. Also make sure the radiator is topped up with sufficient coolant. Funny enough, the mechanic should have taken care of this process after replacing the thermostat....

Car overheating problem


Try replacing the thermostat. Sometimes they can create a problem like this when they are not opening and closing at the proper temp.

You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.
