Where does the coolant go in a Honda Civic?
Coolant doesn’t just disappear. It either goes on the ground (external leak), in the passenger floorboard (heater core), in the engine oil (head gasket), gets burned up (head gasket, or possibly intake gasket), boils off, or it stays put. I won’t address any of the stuff that you’ve done, but I will add:
What causes milky dipstick on Honda Civic ESI?
Intermittant faults can be the very hardest of faults to determine. I’ve had a 94 del sol or civic esi some time back and had all sorts of diagnostics done to no avail. Radiator replacements, coolant tried em all. Eventually it all came down to that dreaded day that i have found a milky dipstick due to a a bad cylinder head gasket.
Why is my Honda Civic running so hot?
It’s possible that there’s an external leak on the exhaust that is burning up the coolant before it hits the ground. When your engine is hot, pop the hood and look closely for any steam coming out while the engine is running. Once again, the coolant is going somewhere.
What’s the boiling point of antifreeze in a Honda Civic?
It could be boiling off, and overfilling the overflow tank, but that would leave a noticeable pool of coolant on the ground, and coming out of the tank. Boiling point of 50/50 mix distilled water and ethylene glycol antifreeze is about 265F.
Why is water boiling out of radiator in Honda Civic?
When it is sitting idle and the temperature is in normal operating range, the water is contsantly boiling out. We have bled the system as directed but no luck. When you step on the gas peddle the water will shoot out of the radiator with the cap off. The top hose is hot, the bottom is cool but does not feel like there is any pressure.
Why is the top of my Honda Civic so hot?
The top hose is hot, the bottom is cool but does not feel like there is any pressure. If taken for a test drive the temp is fine for a while but then it climbs up as you accelerate, let off the gas and the temp comes down. The 2 fans are working. Any suggestions. I will be doing a compression test tomorrow just in case to check the head gasket.
What was the problem with my Honda Civic?
White smoke/steam started was coming out of the hood. Pulled over, turned the car off, popped the hood and the fluid in the reservoir was extremely hot..bubbling and pouring out. This guy helped me out, took off the radiator cap, a white/brownish foam was pouring out of the reservoir/radiator.
What to do when coolant stops draining from Radiator?
Drain the coolant, then put the tank back in its holder. 5. When the coolant stops draining, tighten the drain plug in the bottom of the radiator. Apply non-hardening sealant to the drain bolt threads and reinstall the bolt in the engine block. Tighten it securely. continued Maintenance Cooling System 6.

Why is my Honda Civic overheating while running?
It’s possible that there’s an external leak on the exhaust that is burning up the coolant before it hits the ground.

Find out where it’s leaking and you will solve your problem
Why is coolant leaking from my Honda Civic?
If so, the coolant is leaking into the combustion chamber, and being burned off. This indicates a problem with the head gasket. Is there any coolant on the ground? You should be able to pretty easily determine where it’s leaking, if there is such a leak. Check the passenger floor to see if it’s very wet.

Why is my Honda Civic not cooling properly?
In cases like that the coolant is no longer cooled mostly by airflow through the radiator. When you stop the temperature spikes and the thermostatically controlled electric cooling fan starts…and runs until temps. are brought below the lower limit of the sensor that controls on/off of that fan.
What to do if your Honda Civic overheats?
Check the oil cap for white spots. This is a sign of engine oil contaminated by water, and it could lead to overheating. Check the coolant reservoir for leaks due to a cracking or faulty cap. Check the radiator cap for a faulty spring mechanism.
