    DIY: Mishimoto half length radiator install on a 1997 Honda Civic

    Applicable Years: 92-00 Honda Civic

    Difficulty: 2 out of 5

    Estimated Time: 2hrs

    Upgrading your radiator to increase engine performance and cooling efficiency is really an easy task. And Mishimoto makes an affordable aluminum radiator to do just that and the quality is great. I finally decided to replace my Koyo radiator. It was too thick causing it to hit my turbo being forced to sit crooked, not really being secured.

    [​IMG]

    Here is a comparison of the old Koyo and the new Mishimoto. You can see the Mishimoto is a bit thinner and not quite as wide, which will fit just perfect in my engine bay.

    Mishimoto Honda Civic Radiator 1992-2000
    The half length civic radiator is a perfect upgrade for anyone looking to increase engine performance and cooling efficiency. Popular among import tuners, this half sized radiator can also be tailored towards B and D series motors in custom applications (note: Mishimoto cannot give technical or installation help on custom application installations).

    Model: MMRAD-CIV-92

    MSRP: $250.00

    Tech Specs

    Core Size: 350mm x 358mm
    Rows: 2
    Inlet: 32mm
    Outlet: 32mm
    Core Thickness: 42mm
    Tank Wall Thickness: 2mm
    Fill Neck : 31mm

    Note: This item is for Manual Transmission vehicles. For automatic applications, please purchase optional Mishimoto transmission cooler (P/N: MMTC-U)

    Purchase Includes: Mishimoto Radiator, Mishimoto 1.1Bar Rad Cap, 1 Year Warranty

    Installation:
    1. To start, jack the front of the car up using the recommended steps in your operators manual.
    2. Next remove the drain plug, draining the coolant into a drain pan. Remove the radiator cap to help the fluid flow faster.

      [​IMG]

      [​IMG]
    3. Once all of the coolant is drained you can remove the upper reservoir hose, upper radiator hose and lower radiator hose.

      [​IMG]

      [​IMG]
    4. Next unbolt, unplug and remove the radiator fan. I was using a slim fan in "pusher" mode in front of the radiator.
    5. Once everything is disconnected from the radiator, remove it.

      [​IMG]
    6. Install the new Mishimoto radiator into place. Making sure the feet seat correcting below.

      [​IMG]
    7. Mount and connect the fan. I had to switch my slim fan back to a puller since it is now back in the stock position.

      [​IMG]
    8. Reconnect the upper, lower, and reservoir hoses.Now I just need to get a new upper radiator hose since mine is to short.

      [​IMG]
    9. Fill the radiator up with 50/50 mix of coolant and distilled water.
    10. To bleed the system, allow the car warm up to operating temperature with the radiator cap off to allow air bubbles to escape. Shut the car off and refill will coolant and replace the cap.

    Great write-up :thumbs up.

    Might sound silly but do these type of radiators help at all with stock motors (particularly a D-Series)? Or would it be the same as just buying any radiator? Just curious that's all.

    Does anyone know off the top of their head the fan size for a 6th gen? If I swapped my rad with this one, I'd like to do the fan too.

    By the way, nice write-up.

    Actually, im 99.9% sure you want to fill it up cold, or while its running, Dont let it warm up. Unless you really feel like taking a risk of replacing your block

    i just installed my fullsize mushi in my DC2....damn it looks blingin...makes bay look more appealing...

    since im not running a slim fan, i had to trim a little bit plastic off my stock fan so it wouldnt melt on my header and a simple 3 or 4mm notch for the upper rad hose...i did it with a knife in couple min, nothing to sweat though..... only thing was once i started the car it started pissin a lil stream out of the fluid release nut inbetween the rubber gasket....but nothing that lil teflon tape couldnt fix.

    so it works the way it should and fits like a glove. im happy with it.

    The stock fan will bolt up to the Mishimoto radiator. I assume you have a 92-00 civic? I also just pm'd you a price on a radiator if you are looking to buy one.

    How's the fitment between the top of the radiator and the upper radiator support? My Koyo (just like what JayJay replaced in his write up) doesn't clear the upper rad support, i had to push the radiator down as far as i could, then wedged it under neither the upper rad support.

    Yes, the radiator will work with your Automatic transmission, however, you would be required to run a transmission cooler. We actually offer those, too.

    Let me know if you have any additional questions!
