Advice needed ASAP!

Hello, again,,, Last night i was told by a neighbor to i might have an air bubble trapped in the cooling system. I raised the front end, removed the radiator cap, turned on the truck and ran it till warm During this time i started adding antifreeze in the radiator until it was full. I could see movement of the the the fluid rise and drop. I closed the radiator cap, ran it for 5 more minutes and turned it off. I checked the oil and no milky sludge, still clean.
Here is where it gets strange; i checked the coolant in the reservoir and it was nearly empty. Last night it was just below the Full line. I still dont know whats going on?

 

As others have said, a pressure test is in order. You've covered the basics for at home, at this point any suggestion is a shot in the dark. Spend the few bucks to test it, you'll spend a lot more throwing parts and coolant at it trying to figure it out on your own.

 

Dude stop messing around with you truck and take it to a reputable shop. You are going to fry that motor and need an engine replacment, when all you need right now is most likely a water pump. Posts like this,

,tell me you have no clue what you are doing. TAKE IT TO A SHOP.

 

Lets talk about cooling systems and their basics... First, the reservoir is an accessory to an cooling system and is not needed, EPA and other female hippy's with armpit hair enacted rules to capture chemicals and other bs.. (see pcv)

Since the world is round and spinning, the coolants gravitational pull will sometimes locate it in the resi depending on the axis shift..

You cant really look into the rad due to the fill being a flange rather than top of the core too...

in this world of contraction and expansion you're bound to earn air space in the rad..

 

Thanks.
PS How do i move this thread to the AZ B.S.? Any AZ people who can recommend a reputable shop? Im located in Chandler.

 

Did it for you . Go check out AZBS last page. Don't take to long this mofo moves fast and there is a aluminum foil ball going up for bid today.

 

Cooling system must be 100% air tight. Truck gets hot, some fluid goes to overflow, truck cools down and that same fluid gets sucked back into radiator. If there is a leak it will suck air.

 

An 06,its a good time too put a new thermostat in your truck.
