Thought I would trade my 96 4 runner and 98 crv that had a list of issues and back tax. For one car. Just got this civic.
So the hot temp water warning is always on as well as the hot temp light on dash. Even if car sits overnight I turn car on, and boom these warnings on always on.
Radiator is holding fluid and has not overheated on me, even when I let it idle for a long while never overheated.
What could it be?
Think I made a decent trade?
Didn't this problem show up when you had a mechanic give that thing a pre-purchase inspection?
See the troubleshooting section of the FAQ for information on dealing with an overheating problem.
The chances that the existing sensor will have the same temperature versus resistance range required by the aftermarket gauge is slim to none. A good aftermarket gauge will come with adapters to fit its temperature sensor to various vehicles.
Like do they control other functions of the car I'm not aware of?
An obvious one you haven't mentioned is the need of the fuel injection system to know the engine temperature for proper operation. Some cars have a separate temperature sensor for that.

Aloha something is wrong with the temp sensor readings so was just going to get a aftermarket guage.
I see some on ebay, that come with sensors. Can I just wire the guage to my stock sensor on bottom of radiator, to the pigtail on it? Instead of using the sensor that comes with guage, as it may not even fit.
Well it would be depend on how the aftermarket gauge is set up. If it's cheap enough just buy it and first just plug it in till the sensor on the car to see if it works or not

Something is up with my coolant temp sensors and pigtails, till I can replace parts. How can I tell temp of my car?
Like maybe a regular thermometer or something? Put on upper rad hose for few seconds? Need some way to tell what my temp is. It says it's overheating my dash, but isn't. And been driving hours everyday for days like this now. Has never overheated but want to be safe
Plz help ty
Install an aftermarket temperature gauge.
@chucktobias waiting for it to come in on wends for now I need something that cost a fe2 bucks that can tell me If it's overheating or not
I can't think of anything you can easily or cheaply do to know the car is overheating while driving it, which is obviously when you need to know. You can use an infrared thermometer to check temperatures but would have to pull over and open the hood to do it.
Bought a infrared scanner
I notice rn it's at idle, red temp light is on. Fans are on. I'm getting a reading in a couple spots on engine showing 216-220 f
I see engine codes 7 of them for temp sensor issues. Like circuit to high or low and other temp sensor codes
Is it normal for 220 f to be that high on idle?
I was thinking until I can fix the temp sensor codes and issues. Either jumping the fans, or wiring a switch to fans. And leave on most of time with a aftermarket temp guage installed?
Just went down a few degrees
If head was truly going. Wouldn't it start smoking and stuff? Never had that happen and I been driving hours a day last dew days doing uber eats
Not necessarily. There are quite a few different ways head gaskets can fail, with different symptoms.
Will a head gasket tester tell me if it's going? What steps should I take to find out if head is blown or going?
A head gasket tester will only tell you if combustion gases are getting into the coolant, which while common is only one way a head gasket can fail. It's certainly worth trying. You'd have to check for other symptoms to get a complete picture.
Wouldn't be a bad idea, along with a head gasket test for combustion gases in the cooling system.
@chucktobias I did notice when I put a new radiator in few days ago and added coolant and started it up and left cap off, it slowly foamed up, but after I kept tapping my finger in the fluid it went away and never came back.
Whats a good spot to shoot my temp scanner under hood for the most accurate reading ?
The area where the temperature sensor is located is likely a good location.

I had to install a aftermarket temp guage, and jump the fans. Original temp sensors weren't working and the one on the radiator actually needed a new pigtail as well. Have not got to replacing all that.
Cheapest option was to buy a $25 temp guage and a $10 radiator adapter for aftermarket sensor.
Anyways my question is, is there anything else that I'm messing up other than the temp sensors telling when fans to come on. Like do they control other functions of the car I'm not aware of?
I figured temporarily a aftermarket temp guage and fans jumped would be OK. Till I got to replacing those sensors and stuff.
