My 1994 honda civic overheated still turning over but wont start we replaced the thermostat fuel filter and a sliced radiator hose, but still wont start

Hope this helps, do this VERY Careful, when over heating Turn ON the heater to full, does it cool down? does the water in the Radiator Boiling?. = water pump, (don't always make noise).
Not boiling?- Check and R&R Heat sending Unit Gage on the Radiator or somewhere on the engine maybe close to the Thermostat..

(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.

There are 2 large rubber hoses leading out of the radiator. One on the upper part and the other on the lower part. The thermostat is located in one end of the lower hose attached to the engine.

Follow the top radiator hose to where it connects to the thermostat housing. Remove the hose. There are 2 bolts holding the housing in place. The thermostat is mounted underneath the housing and can now be removed. To test the thermostat drop it in a cup of boiling water and it should open. Since it is not a very costly item you may as well change it once it's open. When replacing, the spring end points away from the hose.

Typical issue with the 92'-95' Civic. Thermostat is one possibility, yes. Another is that it overheated due to the thermostat or the fact that they have a very small radiator which tends to corrode and become increasingly less efficient, in time causing it to everheat and eventually cracking lengthwise away from the radiator cap along the (plastic) top of the radiator due to steam pressure on the inside of the rad. Inspect the fins on the radiator to ensure they are not turning green and corroding away, this will make a marked difference in your colling capability.

check your catalytic converter, and check to see if you have oil in the water or visa versa

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

that radiator wont fit the civic. it will be too big ... always put the correct size radiator and correct part number radiator in the correct vehicle..

MIGHT NEED TO FLUSH YOUR RADIATOR OUT OR HAVE A SHOP ROD IT OUT FOR YOU.DOES THE WATER IN THE RAD. LOOK NASTY LOOKING,IF SO FLUSH IT FIRST BEFORE YOU TAKE TO SHOP

Follow the top radiator hose from the radiator to where it connects to the engine block. Your thermostat should be directly under the hose there.
