Piston Slap: The Balding Accord?

Last fall we purchased for my son a 2003 Honda Accord with 78K. When we had it inspected the mechanic pointed out that a few of the fins on the condenser were missing, but the radiator seemed to be working fine so he didn’t think it was a problem worth worrying about. Well, shortly after we purchased the car my son had an accident which pulled off the bumper. He has been driving this winter with no bumper, thus exposing the condenser. When he finally took the car in to the body shop they noticed that ALL of the fins are now missing. He said he’d never seen anything like this, no explanation for why they had begun to fail in the first place and continued to drop off. He checked the radiator fluids and took the car for a ride and said as far as he can tell the radiator and condenser seem to be working fine, and to reduce the expense of repairs he doesn’t think we need to replace either but that if we were going to do the work at some point now would be the time. Obviously the fins are there for a purpose. Should we place the condenser since we’ve got the car open doing the other bodywork? Is there any reason we should replace the radiator at this point too? It seems to be working fine.

This is my son’s car and he doesn’t have enough $ to pay for the repairs so we are helping out. We’re looking for ways to keep costs down but I don’t want to do anything foolish.

Your advice would be appreciated.

Well, that’s a new one for me! Who knew Hondas shed cooling fins like male pattern baldness?

Apparently you aren’t the only one with this problem, even if yours is much worse given your lack of a front bumper. Yes you should replace condenser, if you live in an area where air conditioning is more than just a luxury. The fins maximize the efficiency of the system, as the extra surface area helps cool down the refrigerant as it circulates through the system.

The (engine) radiator? Hopefully all the fins are there, but if not, that absolutely needs to be replaced: you might save a bit in labor with the bumper removed. Or not. But still…this shouldn’t happen, even with your bumperless Accord. Hopefully your Accord just came with poorly constructed parts, and the replacements are fortified with plenty of Rogaine.

Fingers crossed on that.

    I am not certain what the tubes in a car condenser are made of. If they are aluminum like the fins, it's just a matter of time. Right now it is less efficient. I am a licensed AC Mechanic (residential) and I can tell you that in a home you are putting the entire system in a bad way. In a car I suspect you are not but you will lose a load of refrigerant. Easy enough to fix.

    Unless it's insanely difficult to replace the radiator on an Accord, I wouldn't replace it. Should have plenty of life in it yet, and on most cars it's an easy job. I don't think I'd worry about the condensor either. If the AC does fail, you can fix it then, it's not like it will leave you stranded. Just sweaty.

  • Brett Woods My 4-Runner had a manual with the 4-cylinder. It was acceptable but not really fun. I have thought before that auto with a six cylinder would have been smoother, more comfortable, and need less maintenance. Ditto my 4 banger manual Japanese pick-up. Nowhere near as nice as a GM with auto and six cylinders that I tried a bit later. Drove with a U.S. buddy who got one of the first C8s. He said he didn't even consider a manual. There was an article about how fewer than ten percent of buyers optioned a manual in the U.S. when they were available. Visited my English cousin who lived in a hilly suburb and she had a manual Range Rover and said she never even considered an automatic. That's culture for you.  Miata, Boxster, Mustang, Corvette and Camaro; I only want manual but I can see both sides of the argument for a Mustang, Camaro or Challenger. Once you get past a certain size and weight, cruising with automatic is a better dynamic. A dual clutch automatic is smoother, faster, probably more reliable, and still allows you to select and hold a gear. When you get these vehicles with a high performance envelope, dual-clutch automatic is what brings home the numbers.

  • Inside Looking Out In June 1973, Leonid Brezhnev arrived in Washington for his second summit meeting with President Richard Nixon. Knowing of the Soviet leader’s fondness for luxury automobiles, Nixon gave him a shiny Lincoln Continental. Brezhnev was delighted with the present and insisted on taking a spin around Camp David, speeding through turns while the president nervously asked him to slow down. https://academic.oup.com/dh/article-abstract/42/4/548/5063004
  • Bobby D'Oppo Great sound and smooth power delivery in a heavier RWD or AWD vehicle is a nice blend, but current V8 pickup trucks deliver an unsophisticated driving experience. I think a modern full-size pickup could be very well suited to a manual transmission.In reality, old school, revvy atmo engines pair best with manual transmissions because it's so rewarding to keep them in the power band on a winding road. Modern turbo engines have flattened the torque curve and often make changing gears feel more like a chore.
  • Chuck Norton For those worried about a complex power train-What vehicle doesn't have one? I drive a twin turbo F-150 (3.5) Talk about complexity.. It seems reliability based on the number of F-150s sold is a non-issue. As with many other makes/models. I mean how many operations are handle by micro processors...in today's vehicles?
