Guide overview

Before you begin

Do you have a 1995 Honda Odyssey that needs a coolant temperature sensor to be replaced? Well, then this guide will help you to do that in a fairly simple and efficient manner. A coolant temperature sensor is an important part for a car as it lets the ECU know when the cooling fan needs to activate to prevent the engine from overheating. If failed to replace with a working one, it can cause the engine to overheat and cause severe damage. Before you start, please make sure your car has been cooled down enough to prevent yourself from getting burned. Once that is done, follow the guide to help you replace a failing coolant temperature sensor.

Step 1

Repair step

⌕

Press and hold the hood release button on the driver's side seat.
Open the hood and find the hood prop rod.
Insert the rod tip into a hole with an arrow pointing at it under the hood.
If you’ve recently driven the car, allow the engine to cool completely before continuing to avoid burns.

Step 2

Repair step

⌕

Remove the three 12 mm bolts on the distributor—two on the front and one on the back—using an impact drill with a right-angle attachment and a 12 mm socket.
When unscrewing the third screw the distributor may fall so have one hand underneath to catch it if it does.
Some oil may start to leak out the side of the engine slowly so be sure to have some paper towels ready if it does.

Step 3

Carefully take out the distributor and place it on top of the engine where it is steady and won't start sliding off.

Step 4

Repair step

⌕

Locate the cable and wiring harness connected to the coolant sensor, then carefully disconnect the harness.
If oil starts leaking out from the engine, use the paper towels to stop it.

Step 5

Step 6
