Hello all! I'm having a problem with my 2000 CRV. It began overheating out of nowhere. I found a cracked hose so I replaced it, assuming that was the problem. A few miles later it overheated again. Long story short, I've since replaced the thermostat and the radiator fan switch (located in the thermostat housing). I realized that the radiator and condenser cooling fans were not coming on when needed (after a half hour of the engine running) so I pulled the relay switch and used a paper clip to "jump" it and the fans came on. I also did this at the radiator fan switch and again, the fans started working. I have checked all of the fuses under my dash and under the hood that are related to the cooling system and they are fine. I'm at a loss! I was thinking maybe the water pump may be bad??? Maybe the water isn't being circulated and therefore not reaching the radiator fan switch to activate the cooling fans??? Also...a/c does not work so is not a factor. Ugggh! This is driving me nuts. Any help would be GREATLY appreciated!!!

When was the last time you had the coolant replaced? If there is air in the system, it can lead to over heats like this.

Just something free to look at before throwing parts at it.

How would I know if there is air in the system and how do I go about removing it?

Here is a good video on the procedure. You do not need the spill free funnel, it just makes the procedure a bit less messy.
