Cooling question?

see the point in trying to touch, squeeze hoses. If there is a puddle on the
ground, there should be enough flowing out that you can track it back.

well the logic is that the components have plenty of age on them thus its time to change them any way that being said I stated that the coolant is coming from the cap on the ET. if you look it states on it that it holds pressure until a certain amount and once that limit is reached it will let the excess out. thus my point about my system

i dont feel coolant flow i have 4 other suvs and cars and all of them once the engine is at the proper temp you can grab either lower or upper hose and give a squeeze and feel the flowing coolant but on my x5 i dont. thus it defies logic in the sense that my x5 should be overheating but its not and i drove the shit out of it so i know it was hot but nothing wont go past the 12 oclock but the lower hose remains cool to the touch which i have never felt on any car the the lower hose is always warm to hot but of course not as hot as the upper....

i hope this makes sense now


PS: the car was under warranty till 100K so it had 2 thermostats perior and one pump i think one around 50K and the next was near 90-100K but it failed around the 130K ( only went above the blue if i was stopped no codes )
