I can give you a rundown on how it goes.

1. Drain the fluid into a container by turning the drain nozzle at the bottom of the radiator.
2. Remove the two 10mm bolts from the upper radiator mounts
3. Remove the upper radiator hose from the block.
4. Remove the lower radiator hose from the block
5. Unplug the fan at the wiring harness.
6. If you have an automatic, you'll need to disconnect both transmission cooler lines from the bottom of the radiator. Be aware of how much transmission fluid you lose, and make sure you top it back off after the new radiator is installed.
7. Remove the radiator from the vehicle. Two rubber mounts are located at the bottom. Sometimes they stick to the radiator, sometimes they stick in the hole they are mounted in. Make sure you grab them, you'll need to reuse them.
8. Swap the upper and lower radiator hoses to the new radiator
9. Swap the radiator fans to the new radiator. Make sure the lower transmission cooler line mounts are tight (don't overtighten though)
10. Put the two lower rubber mounts back into the holes on the vehicle.
11. carefully reinstall the radiator back into it's position, making sure the bottom of the radiator slides into the rubber mounts.
12. Reinstall both Transmission cooler lines
13. Plug in the fans
14. Install the upper and lower radiator hoses.
15. Install the two upper radiator mounts.
16. Fill and bleed coolant:

Quote:
A/T capacity: 1.98 gallons -- Manual: 1.98 gallons. The Reservoir (.69 gallons) included in the 1.98.

Before you begin, turn ignition to ON and move climate control knob to 90 degees slowly. This will open the water control heater valve.

With the engine off and cold, Remove the radiator cap. Next, loosen the air bleed bolt on the water (coolant) outlet. It is a 12mm nut. Mix the Honda coolant/water 50/50 or buy Honda premixed. Slowly pour coolant into the radiator fill neck until the coolant starts to run out of the bleed bolt in a steady stream without bubbles. When no bubbles are present, tighten the bleed bolt. With radiator cap off, start the vehicle and let it run until warm and the fans cycle ON/OFF at least twice. Add more coolant to the filler neck to bring coolant level up to bottom of the filler neck. Replace radiator cap, run engine and check for leaks.

Do not forget to add coolant to the reservoir to the MAX level.

When I did mine yesterday, I loosened the bolt, and added coolant until it was at the top of the filler. No coolant exited the bleed bolt and the vehicle was level. I retightened the bolt and started the vehicle. As the themostat opened and the new heater hoses filled, I had to add coolant. I bled the bleed a couple of times and then installed the cap. When the fans cycled a couple of times, I once again opened the bleed bolt until the coolant had no bubbles. I tightened the bolt, filled the reservoir to MAX and shut it down. Today I had to add about half a cup of coolant to the reservoir to bring it back to MAX.
Good luck

I just had mine done yesterday, they installed a CFS radiator, thermostat, gaskets, etc.
The seller on eBay is covering the tab... $560.00

It is very very easy to change the radiator just alot of parts you have to disconnect and swap out. Just remeber when it comes time to pull the radiator out if it feels stubborn to come out RE-CHECK to make sure you have every harness , every hose , and every screw disconnected, when everything is de-tached in the radiator it should just lift right out of the engine bay with no difficulty.

I don't know anything about them, the shop that did it said they use them exclusively and never had problems.
The CFS is plastic, what came out was all metal.
These people did all the service on my 1st Legend, never had issues with them.

Do yourself a favor and don't drive the car too far/hard/long when it's low on coolant! Quite possibly, this is one CAUSE of the blown head gaskets on these cars!

Look for a post from me regarding blown head gaskets in the near future.

3/8" ratchet
10mm socket
10mm wrench
12mm wrench (for bleeder valve when you're done)
screwdriver (if the hose clamps are not OEM)
pliers good enough to grip the OEM hose clamps (squeeze type)

That's about it.

Will that work with my 91 automatic?
On the site when it asks you what type of car you have and what options you have but it didn’t ask if I had an auto or a manual and I thought that an auto had to connect to the radiator.

Thanks for all the help especially with what might seem like dumb questions but it’s really appreciated.
