No. Fill up the the radiator run it for about 5 min open cap and fill it up some more. Then run it like normal for a day or so. then pull off cap again and make sure its still full. what happens is when it runs all the hoses and everything fill up. there is no bleeder but there is an overflow clear tank. it looks like a windshield washer fluid tank. it has 2 marks on it. One when the motor is hot full and the one when the motor is cold. full.

Starting point for firing order

Starting point is always cylinder 1, on straight engines at the front, on V engines front left. The gear wheel or crank sensor will register at TDC or just before. TDC can be found with a pencil inserted in the spark plug hole of cylinder 1
So for a 4 cylinder engine it's 1,3,4,2
6 cylinder straight, 1,3,5,6,4,2,
Cant remember the v engines but it's always left right etc.and from end to centre.

How to purge radiator on a 2003 GMC envoy

Install a back flush kit on the engine. Connecting a garden hose to it will push any air in the block into the radiator so you can see when the air has been purged.

2002 E350 still overheating? New Thermostat, and new spark plugs. Drained & Flushed cooling system - radiator not blocked. No leak from water pump. Catalytic converter became red hot once while reving...

With the vehicle cool, remove the radiator cap, and manually pump the lower radiator hose until all the air is out of the system. That is how you get the air out of the system. If it is still overheating from there then you should check the fan to make sure that it is working correctly.

The engine is running too cold. The problem started after I back flushed the system and have tried 2 new 192 deg stats. I opened the bleeder valve when I refilled the water and coolant (using the correct...

what is too cold, the engine operating temperature should be anywhere from 185 to 210, if you had air in the system the enging would over heat not run cold, only typical too cold is a stuck open thermostat, if your talking your not getting heat out of your vents then you probaly do have air in the system the 3.1L and 3.8L on the front of the engine next to the crossover pipe and the upper radiator hose connnection at the engine has two bleeder screws to realse air since the radiator is below the the engine and air goes to the top only so when your engine is cold and there is no pressure in the system open the bleeders and see if you get air before coolant bubbles out. then finish filling the radiator

No heat at all coming out of the heater!!

these trucks are famous for plugged heatercores,what you do is,remove both hoses to heatercore at firewall, mark there location, next cut two peices of heater hose, about 12 inches long, slide on the heatercore where the hoses where, then use a water hose and flush in both directions a few times, then you should have heat, also if its been a while i would also have the cooling system flushed out, hope this helps. good luck.

Cooling system is air bound, how can I bleed it out?

Look for bleeder valves somewhere on the top of the cooling system. If you see any use them to remove trapped air. Start the engine and slowly turn the screw to remove trapped air. If there are no bleeder screws then remove the radiator cap from a cool engine. Make sure the radiator is full. Start the engine and watch for escaping air bubbles. Keep the radiator full at all times. When the engine reaches close to full operating temperature and you see no more air bubbles escaping put the cap back on. You may have to do this one more time if you experience any more trapped air in the system. Just make sure to look closely for bleeder valves. They will look like tire valves with a cap.

Need help with coolant flush on 2002 pontiac montana....bleeder valves....

Many cars have problems with air trapped in the cooling system because the cylinder head coolant passages are higher than the radiator cap. Park up hill and leave the radiator cap loose. Run engine until thermostat opens, hot upper hose. Keep reservoir full, let cool down repeat. Make sure heater is on all the time.
