Coolant-->Leak or NOT BLED???

[SHOup&SHOout]

My mechanic told me recently that the SHO has a unique cooling system that NEEDS, i repeat, NEEDS to be Bled properly after you change a T/S, Hose, Radiator, etc....Is this true....?This is coming from the same mechanic that took 4 hours to figure out my CrankPositionSensor was gone at around 60-70k..?

Reason im asking is because i recently developed a leak in my cooling system...Found out it was a combination of 2 things....Hose had ruptured...and my overflow bottle split along the seams on the bottom....I fixed the bottle with Marine Grade 5200 Sealant and replaced the hose....But now everyonce and a while i need to add coolant and i smell coolant burning off....at first i thought it was just the coolant that had sparyed the motor when the line ruptured and i needed to refil it because the air bubles were bleeding themself into the overflow bottle??...but now im worried that by not bleeding it when i replaced the hose i did something to the system...

Any thoughts are appreciated...

Thanks....

dont know if this will help but i recently changed the T/S too....The mechanic bled the system afterwards when he was replacing my fan motor....(i overheated).....I replaced it with a Stant T/S...Without Jiggle Valves...I know the Motorcrafts have 2 jiggle valves but could this be causing any negative effects other than a more active temp gauge?

Just some more info...

Any cooling system if in good condition will rid it self of all air in time. This means no leaks and a good sealing pressure cap.

As the pressure rises in the cooling system the air will dissolve into the coolant and remain dissolved until the pressure drops again. And as the temperature rises the coolant expands out in to the overflow tank carrying with it the dissolved air.

I should also add that it is easy to more completely fill the system by leaving one of the TB hoses off while filling. This will allow most of the air trapped in the system to be purged as you fill. But maybe this is what you mean by being bled??

The jiggle valves are there to provide a way for air to escape the block, so not having them will make it harder to get rid of the air.

The SHO motor isn't all that special as far as cooling systems go, but it can be difficult to get air out of the block even when you have the jiggle valves. You can encourage it a little bit by hand pumping by squeezing the upper radiator hose. With the rad cap off (and the system cool) you can often tell if you're getting air out by monitoring the coolant level in the rad while you squeeze the hose.

The pumpkin has something wacky with the cooling system and I wind up draining it, changing things, and refilling fairly frequently, and this is usually what I do to get a lot of the air out.

If you want to get really fancy you can put a tap in the coolant path through the throttle body (if your coolant still runs there), as that's the highest point in the system. Letting air out there is pretty effective.

Coolant

Aside from what was mentioned from all above responses and you are still adding coolant time to time...make sure that you do not have any slow water pump leak. Simply look under your engine where the Water pump is located and you should not see any traces of coolant towards the bottom of the crankshaft pulley. I had this experience recently and I ended up replacing my 2nd water pump after 160,000 miles.

I'll check the water pump tomorrow....but yes im still adding coolant time to time...as a matter of a fact my LOW COOLANT light came on today again...its not the sensor, im actually low....could it be something besides a hose or overflow bottle??....idk...im gonna chexck the pump tomorrow and see where it stands..she'll be parked for a while so i got time to figure this all out....
