The collapse of the top radiator hose on a 2000 Cadillac DTS can occur due to a failure of the cooling system's pressure or vacuum. This may be caused by a malfunctioning radiator cap, which fails to maintain proper pressure, or by a blocked coolant passage that prevents adequate flow. Additionally, a defective water pump can lead to insufficient coolant circulation, causing the hose to collapse under vacuum conditions. Regular maintenance and inspection of the cooling system can help prevent this issue.
You have to pull the lower radiator hose to drain/flush the radiator
Engine end of the upper radiator hose
radiator hose needs replacing. use and heat will cause hose to collapse when worn out
Or remove lower radiator hose
Disconnect the lower hose
First you get to it then you remove it
Remove the bottom radiator hose. Put a garden hose into the top of the radiator. Allow the garden hose to run until the water coming out of the bottom of the radiator is clear.
On a 2000 Cadillac Catera, the thermostat is located near the engine, specifically in the housing at the end of the upper radiator hose. To access it, you'll need to disconnect the upper radiator hose and remove the thermostat housing. This component is typically situated on the front of the engine, making it somewhat accessible for replacement or inspection. Always ensure the engine is cool before attempting any work on the cooling system.
To change the radiator hose on a 1995 Cadillac Seville SLS, first ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator, then loosen the hose clamps on both ends of the old hose and remove it. Install the new hose by securing it to the radiator and engine, tightening the clamps, and refill the coolant before reconnecting the battery. Finally, start the engine and check for leaks.
Usually in housing at engine end of top radiator hose
The thermostat on a 2001 Cadillac SLS is located in the radiator. To access it, remove the upper hose assembly after draining the radiator halfway.
There's always a partial vacuum formed in the radiator when the car cools, Presumably your hose was weaker than normal.
