    have you done anything to the cooling system? did you replace the coolant or thermostat? this siunds like you have air in the system and you need to bleed the air out. There should be a couple bleedr screws in the sytem. one of the i believ is on the thermostat housing or near there and ther should be a second one on one of the steel coolant lines. while the engine is running you have to open them up and let the air out. this could be a lengthy process as it may take a few tries on each bleeder to get all the air out.

Just replaced the water pump belt on my 2001 Escape. The old one had shredded. Now the upper radiator hose collapses when the radiator revs up. What causes this? Water pump? Thermostat? Please help!


Just a worn out hose. Older vehicles used to have a spring in the hose to prevent this. That cost money though. It is normal for the water pump to pull a vacuum on the hose. Collapsing is an old hose.

2008 grand vitara had radoator hose collapsed


Hoses collapsed when water could not be drawn back into cooling system from over flow tank. There has to be an obstruction preventing water to flow back into radiator when car cools down.

2005 Pontiac Grand Prix upper radiator hose collapses bought new one but still does it


By collapsing you mean sucking together . . If so this indicates a vacuum being generated in the radiator by the water pump especially under rpm,s. This indicates that the thermostat may not be in the right way or you have the incorrect thermostat. I know of bottom radiator hoses sucking in from blocked radiator cores ( they can come with wire coil to prevent this) but it is difficult to see how this could be the same for the top hose which in effect is a delivery hose to the radiator.

The temp gauge on the instrument panel was


Sounds like the radiator is clogged, have the cooling system flushed, the water pump pumps water into the engine and it comes out the top hose to return to the radiator to circulate through it to cool, if the radiator is clogged the water pressure will build on the top hose, also look at the bottom radiator hose, if it collapses when you rev the engine the radiator is clogged, although sometimes the bottom hoses are reinforced with wire to prevent them from collapsing so just because they do not collapse it does not mean the radiator is not clogged.
