Question about 1993 Honda Civic 4 Door

Why are my honda civic radiator hoses compressing?

After a long drive or continuous use I've noticed that the radiator hoses have compressed significantly. When I remove the radiator cap, the hoses decompress and turn back to their normal shape. Radiator fluid is normal in terms of level and colour and there aren't any leaks showing up in the pressure test. The reserve continues to stay level as well.

They will compress when the engine cools off, but if they are doing that a lot, I would replace the radiator cap. Make sure you have the right one, the pressure must be correct on it. This is an item you should probably get from a Honda dealer.

A restriction (usually the thermostat) causes the water pump to pull water from the radiator. But with less coolant flowing out of the engine, it creates a vacuum in the radiator which collapses the hoses.

You need to compress and turn the piston at the same time for it to work.

If the engine cranks but seems like no compression, do check the timing belt. As the belt might have given way or snapped. You have to remove the top crank case cover and black side cover to check the timing belt. Enjoy it

I changed head and cam om a 1989 honda civic lx.now it runs rough. whats the problem?


check for missing vacuum hoses. run fault codes to check for wires not properly connected . Have a compression test done as broken timing belts generally bend valves . IT may not be noticeable but will be enough to affect the engine performance.

Did the timing belt break? Are you 100% that it is "in time" correctly? Does it spin over effortlessly? If so,do a compression check,and make sure you dont have any bent/broken valves,or blown head gasket.

1999 Honda Civic LX Stalling/Overheating!!!


(I don't know much about cars so bear with me).

I've had problems of overheating previously where my car's thermostat would hit 140. I think I've fixed the issue, I've replaced the thermostat but it was still doing that and 2 hoses blew and needed to be replaced. I've had to consistently fill my radiator with 50/50 antifreeze on a daily basis to ensure it won't overheat, so far that seems to be keeping the peace.

But now as of 5 days ago, I'm experiencing these new issues of stalling. Upon taking my civic into my mechanic, his meter showed that there was a misfire in the 2nd cylinder a month prior and now all 4 are misfiring. He thought it was the head gasket at first. I had just recently replaced the spark plugs with NGK Platinums, new spark plug wires and a new distributor cap.

I've received many possible culprits to my problem consisting of possibly the Throttle Position Sensor, Fuel Filter/Injection, Distributor or a radiator cap. I'm financially strapped at the moment and only could afford the radiator cap which didn't solve anything, however my radiator is running on 80% water at the moment. I'm really at a loss and I feel like I've done what I could and I'm at my wits end. Please help my poor little Civic cheat death for a little longer.

Sounds like the thermostat is not working properly on your car. I would suggest changing it out, and

getting a radiator flush. if that thermostat freezes shut and does not open when the engine gets hot.

you could have bigger problems, like a blown headgasket, ruin your water pump or rupture radiator

hoses. good luck!

Hi, I have a way to test for a blown head gasket. Since you have good compression, yours would have to be small. Recommend you park on an incline, remove the radiator cap, set the heater on high, start the car and let it warm up until there is flow in the radiator. Fill the radiator and keep it full while the engine continues to run. Look for any bleed ports the system may have either in the hoses or at the attach point housings. Crack any bleeders open to allow any air out. Top off the radiator all the way to the neck and make sure there are no bubbles coming up. Bubbles coming out the radiator are an indication of a blown head gasket.
Please let me know if you have questions, and thanks for using FixYa.

HONDA CIVIC 1992 HEATING UP. i CLEAN THE RADIATOR WATER PUMP IS WORKING FINE THERE IS NO WATER LEAK - BUT STILL LOOSING WATER 1/2 LTS EVERY TWO DAYS


You may have a small pin hole in one of your hoses that is only leaking under pressure. Of course you may not notce it with the vehicle idling because the pressure is higher as the rpms rise while you are driving.

More importantly though, you need to check your oil dipstick. If the oil looks "milky" you may have water leaking into your oil. This can happen if you have a problem with your "heads" such as a small crack. A cracked head can lead to a blown motor so check it out as you are checking all of your hoses on your cooling systems.

Good Luck!

A compression test would be the next best thing because if you are sure that it is engine oil in your antifreeze then it could be a head gasket, but it you don't get a bad reading from the compression test then it might be a intake gasket
