Coolant flow


Asked by May 09, 2017 at 12:48 PM about the 2000 Cadillac DeVille Sedan FWD

Question type: Maintenance & Repair

I have a 2000 deville base. What would cause the coolant flow ,not to flow
through the bottom hose at the thermostat? It seems like the top hose is
getting hot and the other isnt, but the thermostat housing gets really hot.

Stuck thermostat, clogged radiator, or clogged coolant ports in motor. Sounds like a thermostat not opening. Remove thermostat and boil water and drop thermostat in the water and see if it opens in water above about 210 F.


Did that before I put it in. The 1st one was bad. Now if it's plugged inside the motor what would you do?


Flushed the whole system out.
