    Hello fellow CR-V owners! I’m a new owner of a 2001. Her name is Ruby. She just hit 200k miles. I deliver mail so she gets a good workout and only about 4K route miles. I’m interested in seeing what I can do to keep her cooler in these humid hot Missouri summers. Currently she’s getting a...

  3. Shutters in front of radiator not closing in cold weather

    Gen 5: 2017-Present CR-V
    I am wondering if any commenters have had issue with radiator shutters not closing in cold weather? I just had the re-call done at the end of Nov. on my 2018 CRV. I am still unsatisfied with the cabin heat and continued rise in oil level. However I noticed today that the bottom 2 shutters...

  5. radiator

    Gen 1: 1996-2001 CR-V
    I noticed last week that I had a hairline crack in the radiator below the filler cap. Its was fairly long for a crack, maybe two inches. So I figured a new radiator was in order. But first the transmission fluid change needed done, then this week the catalytic converter replaced. It seems the...
  6. 2010 Radiator fan doesn't turn off

    Gen 3: 2007-2011 CR-V
    Like I said above, fan won't turn off. The engine doesn't overheat, there is no check engine light. I've seen it happened before, longest fan stayed on was just a few hours. Then this weekend it stayed on overnight and killed the battery. Fan hasn't turned off since. I have to full the fuse in...
  7. Has anyone tried blocking some of the air to the radiator in cold climates?

    Gen 5: 2017-Present CR-V
    Since the fix is slow to arrive and not seaming to work... I am considering removing the top plastic panel covering the top of the radiator support and inserting a section of flat plastic sled to reduce some of the airflow through the radiator. I had a friend stuck in the middle of no where on...
  8. Radiator replacement: part 1 (prep, parts list)

    Gen 1: 1996-2001 CR-V
    It's time to replace the old, corroded OEM radiator in my '01 SE. It was going to be a $400+ job at the shop so I decided to do it myself. Thought I'd ask if anyone here has done this, and if so, if you have any tips or pointers for me. After double-checking over everything carefully and...

  11. Should I see both A/C fan and Radiator fan spining when A/C is turned on?

    Maintenance and Service
    The A/C system is not running optimally for my Honda CR-V 2008, here are the symptoms: The temperature measured at the center vent can go sub 40F if the car is running, highway or local, but once stopped or idled, the temperature rises up. When the car is idle, the lowest temperature I can get...

    Maintenance and Service
    I have a 2005 Honda CRV with 225k miles that we use and love. We are the original owners and do not have much extra money laying around to get these fixed at a shop. We had a cooling system diagnostic done and were told that the Fan Switch, Radiator Fan, & AC Fan all need to be replaced. I plan...
  13. 2006 CR-V AC and Radiator fans inop

    Maintenance and Service
    Daughter made a quick turn around from college for job interview. I have her car for 24 hours and the ac fan and radiator fans are not operating. I swapped relays and checked fuses under hood, no help. I'm going to check power at relays and jumper fans with power, but I'm having trouble finding...
  14. Radiator Fan Not Working

    Gen 3: 2007-2011 CR-V
    The radiator fan is not engaging. I have checked the relay, fuses, and switches. The fan does engage when plugged in directly into power. Suggestion would be much appreciated. I have reached the end of my rope.
  15. RAdiator Full, overflow empty

    Problems & Issues
    I noticed i have had to add radiator fluid to the expansion tank several times in the last few months. When I check the radiotor its full right to the cap but the expansion tank is empty not even reaching the dipstick. Shouldnt the overflow level mimic the level of the radiotor when car is cold...

    I have a small leak in my radiator near the bottom hose. Hose and clamp appears to be in good shape. Reservoir is a little below the level. My question is, if i replace the radiator, are the mt and automatic radiators the same? The one in the car right now has the tubes on the bottom tank like...
  17. 97 CRV overheating and radiator fan does not turn on by itself

    Problems & Issues
    Hi all - I have a 97 CRV that is overheating while standing still. The temp gauge will go up to 3/4 mark and the radiator fan will not turn on. I can turn the A/C on or heat at max and the temp starts dropping. First I had to fix the temp gauge as that wasn't reading correctly. It is now...
  18. Radiator Vanes

    Dear Honda:
    Cool idea having those slats on the front of the radiator to cut down wind resistance at speed. But, how about programming them to be dependent on temperature too? I notice when going downhill, which is six miles in my area, that the temp gauge drops to the bottom if the ambient temperature is...

    Gen 1: 1996-2001 CR-V
    Recently changed timing belt and water pump. When restarted it will not idle and see air bubbles in rad. Tried procedure for getting air out of system but it just keeps coming. I have tried computer reset several times and no solution. Timing marks are dead on but cant test with light cause it...
  20. Did Honda eliminate the electronic Radiator Louvers from the 2018?

    Gen 5: 2017-Present CR-V
    I have seen a couple of videos on the 2017 that show the electronic louvers that close when the car is at high speed and low temps to block the radiator in order to reduce drag at high speeds, but I have not seen any mention of it on the 2018. I personally kind of thought this might be a bad...
