Hello. Do you have a 6cyl or 4cyl?
Are you boiling over? Have you replaced your radiator/coolant pressure cap? Does your heater blow hot? Did you purge the air from the coolant? Are your fans turning on? Hopefully those questions spur some thoughts about where to check.

This is a great example of asking the right question at the right time!

If I may add, and this I experienced myself, check the rotation of the fan. I don't know how but someone has interchanged the terminals on our CR-V 98 when they replaced the motor fan and so it was overheating when idle.

6cyl My heater it's hot the cap seems fine but guess that's where I'll start I did not purge the air that's another thing I should check but it started over v heating before I drained any coolant my fans turn on but seem to turn off rather quickly in my opinion I'm going to have to see tomorrow if they stay on consistently


My opinion is that it's the fans because I had a bad control module maybe bad control module could have messed up the motors on the fans but I really have no idea

If the car is running hot those fans should be roaring. Is the gauge telling you its hot or is it boiling over? Its possible you have a faulty temp sender. Any fault codes?

No codes and to be honest I haven't checked the coolant to see if it's boiling but I soon as I start seeing it go up I blast the heater I'm going to have to check today

Good idea. For me in the past with other cars if it is not leaking out (obviously), or steaming out the tailpipe, there is air trapped in the system (heater would be cold), the thermostat is installed backwards or upside down (jiggle pin should be at top) or the radiator cap is bad and it cant keep enough pressure so it boils over.
Here is the list from the factory service manual.

Fans barely turning is a problem. You could buy a cheapo one from Amazon (I did several years ago with good results) or ideally you would test it to verify before buying.
I am attaching the FSM procedure below. Good Luck.
