Which way does a thermostat go in on 2005 dodge grand caravan 3.3L?

The thermostat for a 2005 Dodge Grand Caravan 3.3L engine goes in only one way. There are usually alignment tabs or a specific shape to the gasket/housing that prevent it from being installed backward. Forcing it in the wrong direction could damage the thermostat or housing.

Do not try to force it.

Instead:

1. Consult your repair manual: A Haynes or Chilton manual specific to your vehicle year and engine will have diagrams showing the correct thermostat orientation.

2. Examine the thermostat housing: Look closely at the housing where the thermostat sits. There should be indicators (like a raised lip or a specific shape) that show the correct position for the thermostat. The gasket will also likely only fit one way.

3. Inspect the thermostat itself: Sometimes the thermostat itself has a small arrow or marking indicating the direction of flow.

If you're still unsure after careful examination, it's best to seek assistance from a qualified mechanic to avoid damaging your engine. Installing a thermostat incorrectly can lead to overheating and significant engine damage.
