According to Kat's, the Kat's Heaters Custom Engine Block Heater part # KH11419 for your 2004 Honda CR-V will replace the freeze plug located on the right hand side(passengers side) of the engine on the rear of the engine closest to the firewall which is marked "RR" in the transverse mount engine diagram.

In order to install this block heater on your 2004 Honda CR-V you will want to follow the steps I have listed for you below.

1) Refer to the most current catalog for the correct part number and position of freeze plug heater.

2) Drain the cooling system, flush radiator and block.

3) Remove the correct freeze plug or existing heater with a punch; be careful not to nick the wall of the freeze plug hole. Remove any burrs, sharp edges, paint or compound from the machined surface of the hole.

4) Remove outer O ring from heater, place in hole with the element in the direction prescribed. The element should not touch anything inside. If it does rotate the heater until the element is free floating.

5) Lubricate O ring and machined surface of the hole with anti-freeze or silicone grease to facilitate installation and prevent O ring damage.

6) Reinstall O ring. Back-off heater nut as far as possible, insert heating element in proper direction, center heater in hole. And press tight. Tighten bolt to recommended torque. Do not use the screw to draw the heater into the hole. Do not over torque the bolt, this could damage the inner O ring and cause a leak or strip the threads of the bolt.

7) Route the cord to any convenient point and tie cord down. Keep cord away from hot surfaces and moving parts. Always have the cord attached to the heater before plugging the cord into the wall.

8) Refill the coolant system. Check manufacturer’s instructions on mixture of anti-freeze. Do not use more that 60% antifreeze. Use of non distilled water could result in lime or calcium buildup on elements and cause premature burn out of heater. Run engine until internal thermostat opens and continue running for 20 minutes to eliminate air pockets. Test drive the vehicle and Check for leaks.

9) Plug heater into power supply and test for proper operation. The block around the heater should get hot. The only way to check a heater is with an Ohms meter or some other device that will check continuity. If the heater shows continuity then check the power supply including extension cord.

The above instructions are generic for all block heater installations and may need to be adapted to your exact specifications.
