2000 Oldsmobile silhoutte th eguage says overheating but engine hot has stalled out no heat coming from vents what could be eproblem?

There could be a few reasons why your 2000 Oldsmobile Silhouette's engine is overheating and stalling out, while the gauge says overheating and there's no heat coming from the vents. Here's a couple things to consider:

- Coolant level: Check the coolant level in the reservoir. If it's low, add more coolant and see if that resolves the issue.

- Coolant leak: Look for any signs of a coolant leak, such as puddles of coolant under the car or around the engine. If you find a leak, it'll need to be repaired.

- Thermostat: The thermostat may be faulty and not opening properly to allow coolant to flow through the engine. This could cause the engine to overheat.

- Water pump: The water pump may be failing and not circulating coolant properly. This could also cause the engine to overheat.

- Radiator: The radiator may be clogged or damaged, preventing it from effectively dissipating heat from the engine. This could also lead to overheating.

- Heater core: The heater core may be clogged or damaged, preventing hot coolant from flowing through it and producing heat for the vents. This could explain the lack of heat coming from the vents.

It's important to have the overheating issue diagnosed and repaired as soon as possible to prevent further damage to the engine. If you're not comfortable performing these checks or repairs yourself, take your car to a qualified mechanic for assistance.
