SOURCE: Bleed cooling system

Assuming you have already filled your cooling system with the proper G12 coolant to the cross-hatch level, open the coolant overflow/fill bottle cap. Leave it off. Start the car and let it idle. Turn your heater on full hot and full fan speed. Let it come up to temp so the thermostat opens up and allows coolant to flow through your system. When the system burps, you'll see air bubbles show up in the overflow tank. Let it cycle a another time and then top off the coolant if needed. Then close up the cap and call it a day.

SOURCE: 99 deville...how do you bleed out air from cooling

There is no need to bleed air out of the system as the Northstar is self purging.

If you are having overheating problems the most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank(Not the cap!),this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.

Air locks in the Northstar engine shouldn't be a problem as the system is self purging, given that all hoses are clear.

SOURCE: how do you bleed air pockets out of cooling system in 99 grand am

If a valve is expose on the upper heater hose piping crack that open only when the engine is warmed up for at least 15 minutes. If no valve is seen you will need to loosen one of the heater hose clamps ever so slowly to let the air out. The process to loosen the clamp is not recommended unless you do this first..... When the engine is COLD loosen a hose clamp and remove the hose and put it back on. Thighten the hose clamp snug only. The start the engine to warm up. In about three minutes see if you can twist the hose to move on the fitting. If you can snug the clamo a lttle more and check again. You do not want the hose to come off if too loose. Now that the engine is warmed up for 10 to 15 minutes shut OFF the engine and barely loosen the same clamp 1/4 turn at a time until coolant trickles out. Listen carefully for air escaping too. Air pressure does built up only when the engine gets hot and the air pocket does not move when the engine was cold with the hose removed beforehand. If no air was released upon this proceedure you have a blockage in your system and flushing maybe the only other option using pressure instead forcing the coolant out. Get a can of coolant flush before the power flush proceedure. A radiator pressure tester can be used to power flush with an air fitting adapter installed in place of the guage

SOURCE: Need to bleed air our of cooling system on 1992 Lexus SC400

The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml

When bleeding the radiator i found coolant leaked into power steering reservoir how would this happen


When bleeding the radiator i found coolant leaked into power steering reservoir how would this happen? =============================================
1. Not enough information and you have not identified the vehicle either.


2. Coolant cannot leak to the PS system. They are entirely separate systems and unconnected.

3. If you have an auto transmission then in some models there is a section of the radiator used for cooling the auto transmission hydraulic fluid . IF there is a breach in the radiator between the 2 sections then coolant can flow into the auto trans fluid and vice versa. If you find there is pink hydraulic fluid in the coolant when draining the radiator then it will be auto transmission fluid.

In that event you will need to replace the radiator and to have the auto trans serviced now or the transmission will fail if the hydraulic fluid has been contaminated.

I've eplaced the thermostat on my 2014 HD Ultra Limited. Apparently I was supposed to bleed the cooling system after I refilled it, but I can't find any how-to's on accomplishing that. Any tips?


Remove rad cap while cold start and run engine making sure to keep it full also check for air bleeds along the system usually near tstat or on top most cooling system component

02 ford explorer 4.0 overheating and suddenly blowing cold air, then hot again while engine runs cool but not long


Most likely you have air trapped in your engine, particularly in the heater loop. You need to properly bleed the air out of your radiator cooling system. The hot and cold blasts of air coming from first hot water followed by air.
Read up on how to bleed air out of your radiator system. Some systems are very difficult to bleed.
If after doing a good bleed of the radiator system the problem returns, you may have a bad head gasket or other leak in your cooling system which is injecting air into the cooling system (radiator/water cooling system).

The reservoir is the traditional top tank of your radiator.

2004 dodge ram is over heating, the thermostat and fan clutch have been replaced.Doesn't(over heat) in cool weather,but will in mod. weather if driven over 70mph or hilly terrain due or increase of rpm,and...


Water pumps can stall out, but do you have air trapped in system.
Had you recently had the system "open" to replace hose, thermostat, temp sensor. Some Ford and GM have a bleeder screw on a high point in cooling system to bleed out trapped air.

Check your trans fluid color. Since the trans cooler is built into radiator (automatics)

IF the engine is overheating the trans CAN overheat
IF the trans is overheating the engine CAN overheat

They share the same cooling source and trans fluid gets hotter than oil, but yet it has a wimpy cooler built into radiator. Maybe add trans oil cooler to system.

Also outside temp affects the cool down rate of the radiator, ie...hot air trying to cool down hot radiator/engine is less effecting than cool air cooling hot radiator/engine
