Why is my 2008 honda civic overheating

A Honda Civic’s cooling system is a sealed system, which means that it makes use of strain to boost the boiling level of the fluid inside the radiator. Because the engine operates, the fluid inside the radiator circulates all through the engine. Most overheating issues with these autos will be traced to gasket failure, leaks or to worn elements.

Step 1

Twist the radiator cap off of the radiator after first ready for the engine to chill, then look into the radiator and observe the fluid stage. The fluid stage needs to be roughly 1 inch beneath the highest of the radiator. Add radiator fluid if obligatory.

Step 2

Visually examine the cooling system for indicators of leaks. Even a small leak will step by step decrease the fluid inside the radiator and lead to overheating. Examine the higher and decrease radiator hoses, the seams surrounding the water pump, the thermostat elbow and the radiator itself.

Step 3

Pressurize the cooling system with a radiator strain gauge and examine for radiator fluid leaks. The strain gauge fastens to the radiator rather than the radiator cap. The gauge consists of a pump and a gauge. Because the pump is operated, air will fill the radiator and the gauge will show a strain studying. Pump roughly 15 pounds-per-square-inch (psi) of air into the radiator. If the radiator quickly looses strain, examine the cooling system for leaks.

Step 4

Verify for indicators of antifreeze within the crankcase. Withdraw the engine’s oil dipstick and observe the fluid on the tip of the dipstick. Radiator fluid will seem as bubbles inside the oil. If water is within the crankcase, the cylinder head needs to be eliminated and its gasket changed. If the issue persists, the block and cylinder head needs to be inspected for cracks.

Step 5

Verify for combustion leaks into the cooling system if there are not any indicators of radiator fluid within the crankcase. Pressurize the cooling system with the radiator strain gauge to roughly 15 psi, then begin the engine and observe the needle on the gauge. If the gauge needle strikes erratically, pull every spark plug wire off of its spark plugs, one wire at a time, and observe whether or not the needle steadies. If the needle does regular, that individual cylinder is leaking into the cooling system and the pinnacle gasket should be changed.

Verify the discharge level of the radiator cap with the radiator strain gauge. As a security gadget, the radiator cap will launch the strain within the radiator if the strain exceeds a specific amount. If the cap releases the strain too early, overheating will consequence. The strain gauge’s pump attaches to the underside of the cap. Shortly pump strain into the cap and notice the studying on the dial when the cap releases the strain, then evaluate that studying with the cap’s specified score. A radiator cap’s score varies on the dimensions of the radiator. As Honda doesn’t use the identical radiator in all of its Civics, its caps differ. The pressuring score can be stamped into the cap. If the cap releases the strain early, exchange the radiator cap.

There are a number of the explanation why your Honda Civic could be overheating when idling. The commonest ones embody a nasty thermostat, water pump, electrical followers, and low coolant stage. This information is meant that will help you discover the reason for this overheating in probably the most environment friendly means doable. So, let’s begin with what’s straightforward and take it from there.

In case your Civic is working and driving positive, however you find yourself stopped someplace and it begins overheating when idling, this information is for you. If it’s overheating in any respect engine speeds, take a look at Honda Civic Overheating.

Why is my 2008 honda civic overheating

Make sure that to examine and work on the engine when it is chilly. Electrical followers can kick on at any time.

Civic: Overheating When Idling Causes and Options

1. Low Coolant

Whereas it appears counter intuitive, when your Civic is low on coolant could run pleased with wind hitting the radiator, however when idling there’s simply not sufficient coolant to correctly cool the engine.

Answer: Fill the radiator and coolant reservoir again up. By no means do that when the engine is heat. The chilly engine coolant can “shock” the block and trigger a crack or perhaps a freeze plug to drop out.

Filling it again up is not the repair. The coolant needed to leak from someplace. Look underneath the automobile when it is parked and see in the event you can see puddles of coolant. If there are, begin immediately above these puddles in your search.

Why is my 2008 honda civic overheating

A coolant leak is normally attributable to:

  • Cracked Hoses– There are two hoses that come and go to your Civic’s radiator. One sends the recent coolant again from the engine to the radiator to be cooled. And the opposite one sends the coolant again to the water pump to chill the engine. These hoses can crack with age. Check out them and see if they’ve been leaking. Even when they’re dry, they need to nonetheless have a chalky look to them the place they’ve been leaking coolant (it’s mineral deposits).
  • Radiator Leak– Check out the radiator itself. Figuring out if there is a leak is going to rely so much on whether or not or not you possibly can simply see the radiator. If it has an enormous gouge on one of many fins, or a streak taking place it that appears like coolant has dripped from it, there’s your leak. Right here’s easy methods to discover coolant leak.
  • Water Pump– There are gaskets between the water pump and the engine block. If considered one of these gaskets fail, then there’s going to be a leak. This is typically a tough one to see, as a result of all the equipment (alternator, energy steering, serpentine belt) are going to hinder your view. This is typically the place the leak is coming from when there’s a puddle underneath the middle of the engine bay and also you don’t see a leak anyplace. Listed here are the indicators of a nasty water pump within the Honda Civic.

2. Dangerous Electrical Fan

Why is my 2008 honda civic overheating

If the coolant stage seems to be positive, then the subsequent best factor to have a look at is the fan. Most autos use electrical followers to chill the radiator when it will get heat sufficient. These followers are most vital when the automobile is idling. These followers can and do fail.

Answer: With the engine scorching and idling (however not but overheating) pop the hood open and see if the fan is turning. If it is not turning in any respect you already know you may have a nasty fan.

Verify the fuse and fan relay to see if they’re getting energy. If they’re, you’ll want to interchange the fan. Right here’s a very good information to troubleshooting a radiator fan.

3. Dangerous Thermostat

Subsequent on the checklist is the thermostat. Your Civic’s thermostat controls when coolant does and doesn’t enter the engine. It’ll both be on the block or water pump.

Answer: It may be powerful to inform if a thermostat is dangerous with out simply changing it. Does the automobile get scorching inside a couple of minutes of driving (and the coolant is full)? That could possibly be sufficient to inform that the thermostat isn’t opening all the best way. It normally takes an engine some time to overheat when it is filled with coolant.

You’ll want to interchange it, which is a few 2/10 in mechanical problem. Almost definitely you’ll simply want a ratchet, extension, and 10mm socket.

4. Dangerous Water Pump

Why is my 2008 honda civic overheating

The water pump in your automotive is turned by the Civic’s engine accent drive system. Because the engine rpm will increase, so does the velocity of the water pump. When the automobile is idle, the water pump is turning slowly.

Answer: A foul water pump isn’t environment friendly. When the automotive is overheating when idling the water pump is not capable of transfer the coolant by means of the radiator and again to the engine. You possibly can check this by placing the automotive in impartial or park and revving the engine to about 1000 RPM underneath the redline for a number of seconds. It’s best to see the temperature dip because the water pump spools up.

Changing a water pump is solely as difficult as attending to it. Which, relying on it’s location, will be comparatively straightforward or a complete nightmare.

Right here’s extra on diagnosing a nasty water pump.

Honorable Point out: Temp Gauge

Whereas your Civic’s temperature gauge is normally fairly dependable, it nonetheless is {an electrical} gadget that may fail. A mechanic would examine the temperature of the engine manually with a warmth gun with a purpose to be certain that the gauge was studying appropriately earlier than tackling the restore.

When the automotive is overheating when idling and also you SMELL the smells related to a temp that is too excessive, you possibly can throw the temp gauge concept out.

Conclusion: Honda Civic Overheating When Idling

Hopefully, this information to why your Civic could also be overheating when idle helped you repair your automobile. If there is something that you simply wish to add that would assist the subsequent particular person with theirs, your remark beneath is most welcome.

This is a story that goes again a few 12 months when I discovered my very first automotive. I wanted it to commute backwards and forwards to high school. Once I purchased the automotive it labored nice, every thing I might have wished.

Nonetheless, that quickly modified when it started overheating, and to be particular it is a 2003 honda civic ex, computerized. I took it again to them after having to pay towing bills. They mentioned they did not comprehend it had points (bull) they mentioned it was on account of a radiator, in order that they put in a brand new one.

Once I bought it again it drove positive then it started exhibiting the identical signs quickly after. I made a decision since I cherished the automotive I would not even trouble with the folks I purchased it from, huge mistake and I ought to have simply returned it. I did not as a result of I used to be sick of searching for a automotive and faculty was about to begin. This started the routine of getting to fill it with antifreeze on a regular basis earlier than and after class, if I did not it could most definitely overheat after which I would need to blow scorching air all day. So I took it to a different mechanic who figured it should be one thing fallacious with the cooling system and mentioned the fan was performing gradual, so he changed the fan-switch and thermostat and mentioned that it wasn’t the water pump. I hoped this may do it, but it surely didn’t.

He then examined the head-gasket twice and it got here again adverse. Then they examined the catalytic converter, got here again adverse. This mechanic, then proceeds to inform me the individuals who bought it to me could have put a sealant through which gummed up the engine and is clogging issues so it might probably’t perform appropriately, or placed on the head-gasket fallacious or any variety of issues to the engine. Though, would not this nonetheless make the head-gasket check fail?

He tells me I might have a brand new engine as a result of to determine if it really is an engine drawback that may value as a lot as a brand new engine. I do not know what to do or the place to go I’m at a loss right here. Spending my cash simply to have mechanics inform me there is some mysterious “undiagnosable” drawback with my automotive is probably the most irritating factor ever. Nobody can repair this automotive it appears. PLEASE I encourage anybody who is aware of easy methods to determine this mysterious drawback out!
