Water Temperature Sender Unit Removal / Installation - 3.0L

WARNING: This page is about a different car, the 2006 Mazda B3000. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these instructions could result in damage to the cooling system or engine and/or personal injury. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When it is certain all the pressure has been released, press down on the cap (still with a cloth), turn and remove.

Drain the engine cooling system. See ENGINE COOLANT REPLACEMENT - 3.0L .
