Why is my civic coolant not coming out?
If it has the tube molded into the tank, then there could be a piece of crud in to bottom acting like a one way valve. You can only get rid of this by flushing out the tank upside down. The molded tube could also have a tiny crack near the top that would act the same as a bad tube hanging from the cap.
Why does my Honda Civic overflow radiator?
The reason was not enough coolant in the system, filled up radiator and all OK. Then it happened again and there is coolant in the overflow tank, but pull the radiator cap and no fluid under cap. Fill radiator and all OK, but it kept happening. I replaced the OEM radiator cap with a new “Slant” brand for an ’03 Civic. No better, no worse.
What kind of radiator does a 03 Honda Civic have?
Fill radiator and all OK, but it kept happening. I replaced the OEM radiator cap with a new “Slant” brand for an ’03 Civic. No better, no worse. Last week I had a significant overheating event while on a highway.
How is the expansion tank on a Honda Civic?
The expansion tank is shaped and fitted into a relatively tight space (pretty much standard Honda stuff). To remove the tank and hose looks like I’d have to pull the battery for sure and perhaps some other stuff just to get the tank out to inspect it and clean it properly. If I get that far I’ll replace the old hose with a new one.

Why is the coolant reservoir Bubbling Under my Car?
EDIT: It has been pointed out that the bubbling could be coming from a leaky hose drawing air into the coolant tank. However, a leak that lets air in will also let coolant out; so you would expect to see a puddle of coolant under the car after a while.
Why is coolant bubbling in my Honda Civic?
I was bleeding air from my Honda Civic yesterday. Everything was going well until the coolant was still bubbling after 40 minutes of bleeding. I did everything correctly. Turned the heater to max, I checked the lower hose temperature by touching it to see if thermostat opened. It was hot.
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.
Why are there no bubbles in car coolant?
Automotive coolant tends to work much more efficiently without air bubbles as the lack of air bubbles allows the coolant to absorb heat at a much faster rate than coolant containing air bubbles, making it a more efficient means of keeping your engine from overheating.
Why is my Honda Civic making a grinding noise?
Gunk from the oil in the coolant. Water pump failure could cause engine overheating by failing to pump fluids through the system. The easiest way of knowing if the water pump is bad is to listen to it. Many forum members describe it as a grinding noise, while others describe it like a can being crushed. Either way, it is a very distinct sound.
