How to Replace a Dodge Caravan Oil Pressure Switch
by Shayrgo Barazi
The oil pressure switch on your Dodge Caravan is a critical component that allows you to monitor oil pressure and turn the vehicle off in case it drops significantly. However, the oil pressure switch can fail internally and send a false signal to the instrument cluster, making you think there is an oil pressure issue when there isn't. Another issue that occurs is oil leakage from the oil pressure switch. If either of these problems arise, replace your oil pressure switch immediately.
Step 1
Jack up the Dodge Caravan and place on jack stands.
Step 2
Place a drain pan beneath the oil pan since oil will seep from the oil pressure switch hole.
Step 3
Disconnect the oil pressure switch connector. It is located near the oil filter and will have an electrical connector plugged into it.
Step 4
Remove the oil pressure switch with an adjustable wrench in a counter-clockwise fashion.
Step 5
Place Teflon tape onto the threads of the new oil pressure switch and thread the switch into the hole. Tape is used to ensure that oil doesn't leak between the switch and the threads of the engine block. Tighten the switch with an adjustable wrench.
Step 6
Reconnect the electrical connector.
Step 7
Start the engine and inspect the oil pressure switch for any leaks.
Step 8
Lower the Dodge Caravan.
