1988 Honda Civic dx, temp gauge goes all the way to Max after warm up and stays there without any actual overheating. How can I fix this? - 1

But a new one

The first thing i would do is ck. The temp guage/sensor to make sure it was correct. Use a lazer pointer to find that out, point it at the water neck where the top radiator hose is after its warmed up and see if that temp is the same as what the guage is saying.

If the temp gauge is in the red you are over heating the motor jojo.

  • My breaks pedal goes all the way down? I just changed the master cylinder and break booster on my 1997 Honda Del sol. The breaks still sink all the way down. I still have yet to bleed them. But how big of a difference will bleeding the air out of the system do the my sinking break pedal. Or is there another reason my break pedal would be doing this? Keep in mind I haven't bleed them yet. Any help would greatly be appricated.
  • Honda cb500 1994 temp. Gauge, and oil indicator does not work? Hey guys just got my first honda and of course it's great and i'm loving it, but i have a small issue with the temp gauge. It seems not to work, even when the fan turns on it does not seem to even get up from the bottom. So any ideas what and where i should try fixing? One more thing is that the oil indicator does not light up at the start, any ideas why? The lamp is ok I've checked it already
  • Is there any way I can put in an aux cord to play audio if I only have USB ports? I started leasing a 2019 Honda CR-V recently, and the only inputs seem to be USB ports. My friends like passing around the aux cord when we drive places, and though the CR-V does support Apple CarPlay and Android Auto, switching between a lightning cable and a micro-USB seems like a hassle (since they have different phone models). I found some USB to aux adaptors online, but the reviews on them say that they can't be used to do what I want.
  • Why could my 2000 Honda Civic show it's going to overheat I have coolant a new radiator a new radiator cap a new temp gauge switch and? A new thermostat head gasket is fine could it just need to flushed and a new water pump and timing belt
