Radiator Removal/Install

This rad install was done on a 1994 civic hatchback with a b-series swap….. coming out of the car is a GSR rad, and going into the car is a GSR rad.

1. Remove bumper. There are 5 screws ontop (showing) and 2 underneathe which you will need a 10mm ratchet and 1 in each fender. This should take no longer than 5 mins.

2. Once bumper is off, you will see 2 brackets that go overtop of the rad on each side. Unscrew them and lift up and away (sides) from the rad.

3. Now you can remove the resvoir tank which is beside the rad. Simply unscrew the top of it and take out the tubing. Then lift up the tank and it should slide right out.

4. Jack up the car (I used the tow hooks, because its at the front).

5. Remove the liner that is underneathe the car. It is a hard rubber piece that protects the engine from dirt and scum. There are bolts located underneathe (easy to see), but there are are also bolts in the wheel well (picture)

6. Once that is removed, slide underneathe the car and you will see a little plug. Once you see it, place a pan/jug/etc, underneathe so once you undo it, the rad fluid will leak inside of it.

7. Simply undo the plug and let it drain.

9. Unplug the fan, and lift out the rad. There will be a hose connected to it at the bottom, and there is some slack. So as your lifting, let the rad sit ontop of ur front frame and disconnect the bottom hose.

10. Let that hose go to the bottom and drain itself out some more.

11. Now is the time you get you new rad, and connect your old fan to it. There should be a couple plastic bolts that hold it in, then simply just do what you did from your old rad to your new rad.


12. Slide in the new rad. After you have it in, slide the brackets back ontop on both sides and tighten them.

16. Get a small funnel and put it where the rad cap is. Now get your new rad fluid (mixture of 50 water and 50 antifreeze is best), I mixed myself, did not get a premix. Start pouring it in.

17. Only fill up the rad 3/4 the way through the rad cap.


18. Now add additional rad fluid to the overflow container (resvoir tank).


19. Seal up the rad cap and make sure everything is closed tightly.
