HONDA CONCERTO TEMP GAUGE GOING INTO RED - HAVE RENEWED HEAD GASKET, RADIATOR, TEMP SENDER SWITCH AND THERMOSTAT HEATORS IN CAR HOT AND COOLING FAN WORKING

    my honda civic 2004 sedan is experiencing the same problem,but instead of repairing what you did,I checked the water temperature in the radiator and it was a perfect 105 degrees so that tells me it's an electrical problem in the dash gauge or temperature selector on the dash panel.

    Are you sure the coolant is over heating. It could be a problem with the gauge. or in the wiring.

SOURCE: bottom radiator hose cold. upper radiator bulging.

well - "easy" is relative.
To me - it may be easy - tou you... only you can be the judge.
If you feel comfortable replacing the timing belt properly - then i'd go for it.
Just know - if you have problems - you will have to tow the vehicle to the mechanic.

I have used eBay since the early 90's and have never gotten taken.
The sellers rating is important - and look at the feedback of the seller to make sure they are living up to their end of the deal.

When you have a new pump - re-post and we can give you some help and tips if you want to tackle yourself.

A Haynes manual would be a great help to you also. Look for those on eBay as well. They basically tear down a car and put it bcak together. EVERY PIECE.

there are 2 item located in the same area one is a little below the other.it is on the housing of the one you replaced, the top one is a low coolant sensor and the one on the bottom is the temp sensor.

SOURCE: How do I diagnose a bad thermostat or temperature

You can remove the thermostat and put in a pot of water and boil it.(should open near the stamped temp on yours, 195f) From what you have posted, ti seems that you have a partially obstructed radiator core and at present, it's just bad enough for the electric fan to deal with it. (you can actually see that the temperature fluctuations happen when the fan is on and off) If you do not clean out the radiator, eventually the fan will not be enough to lower the temp and it will begin to actually go into overheat.

SOURCE: 1990 honda accord temp gauge above hot limit.

Hi there,

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.

The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.

So, other components which are likely to cause hot readings (in this order) are:

- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.

- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.

- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).

- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.

- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.

If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.

Cheers,

"if this has helped you in any way, please rate this solution"

SOURCE: 1995 honda passport overheating. We changed the

If the fan is running and the car is really running hot it is a problem with coolant circulation, either a thermostat that isn't opening fully (I have seen intermittent ones) or crud buildup in the radiator. I say really running hot because a defective instrument sender or wiring problem could cause an incorrect reading.I would suggest replacing the thermostat first (or removing it for a while as a test) to see how the temperature behaves, and if it behaves badly a good radiator flush.When u filled the car up with coolant did u open the bolt to purge the air in the system.I had a accord that was doing the same thing .the bolt to purge air on my accord was right beside the thermostat.just a suggestion with what info u have given. if so It might be the Head Gasket caused the car to overheat.

My car heats up in stop n go traffic. The temperature gauge can go as high as to the 'RED'. I adding water and coolant everyday. Are the fans supposed to come on as I am driving and the car heats up?


if you are adding coolant every day then you are experiencing coolant loss
could be from a leaking pump gasket , head gasket or other leaking item
have a compression test done to check for head gasket , cracked head
next have the cooling system pressure tested to find the cooling leak
lastly check the fan, fan relay , fuses and coolant temp sensor unit for correct operation

What's chances that the temperature gauge or sender itself is wrong?
Is the heat exceptionally hot? What temperature is the heater dicharge when the gauge reads 260?
I think that the sender is not expensive, try that. An auto parts store could get you an inexpensive dial gauge that you might be able to install in place of the sender.

Temperature gauge goes in the red. i replaced thermostat. engine does not appear to be hot. could it be an electrical wire causing the gauge to go into the red.


You most likely have a blocked radiator based on the vehicle's age, which will not allow all the coolant in your cooling system to circulate enough to cool the engine. The fans that blow on the radiator won't help much when this happens and at a stop the motor will get hot and the gauge will go in the red because the vehicle really is getting too hot. Just because you don't see steam erupting from the engine compartment does not mean the vehicle is not overheating. It is not very likely electrical short or related issue would make the gauge read high.

What can cause water to get very hot and be pushed out into the the coolant reservoir in a 1993 Toyota Camry LE v6?


Several things ... best guess, in order:
1. (very likely) Radiator fan is not blowing (turn on car and a/conditioner. When compressor kicks in, the radiator fan must blow). If it ims not blowing, the radiator fan motor may be burned out ($40).
2. Check / replace "cooling fan" fuse ($1) and / or "cooling fan" relay switch ($7).
3. Could be (not likely) thermostat sticking shut. Replace thermostat ($20)
4. Could be radiator hose collapse (not very likely) ($18)
5. Radiator clog or hose leak (possible)
6. Head gasket broken (not likely unless you don't fix current problem) ($150)

The more detail of the symptoms, the better we can assist you.

Hope this helps!

Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.

2003 Honda Civic runs hot when idling.


Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.

2000 Elantra Overheating


First when vehicle is cold like in the morning check and make sure that the vehicle has enough coolant/ antifreeze in radiator and reservoir. If coolant is need use a 50/50 mixture of water and antifreeze. You will need some time to do this let car run at idle until the temp guage is in the middle NOT+ normal operating temperature. At this point if the thermostat should be in the open position. Let vehicle run and check to make sure that radiator fan comes on. This should come on when guage is about midway/half way. If temperature rises above half going to h/hot and fan doesn't come on, you either have a BAD FAN BAD FAN SWITCH BAD FAN RELAY OR BLOWN FAN SWITCH FUSE. You will need to check all of the following I will help if its needed. If fan comes on and doesn't go off and vehicle continues to get hot even with fan running. Feel radiator hoses and see if the lower radiator hose is cool/cold. If it is you have thermostat that stuck closed. Replace thermostat and fix problem. If all the above is good and vehicle continues to over heat. THE BAD NEW IS THAT YOU MAY HAVE A BLOWN HEAD GASKET /CRACKED HEAD /BROKEN WATER JACKET. Basically you will need a HEAD JOB at least a head gasket. ONe tell tail sign of this is oil looking like milkshake/chocolate milk-a creamish while residue in oil or antifreeze. Contact if you need hel0p. Good Luck and thanks for using FIX YA
