Question about 1998 Honda Civic
First of all it started overheating and I noticed that the antifreeze spills from under the car. Also, I turned on my car a few days ago and I noticed that it was shakey and all of a sudden the engine light started blinking. I used my car like that anyways and noticed that when I would accelerate it kind of pulled back several times. I check the antifreeze in the car frequently and yesterday when I got home it was starting to over heat. I suppose that all the antifreeze spilled. What can the problem be? Please help!!!
Suspect internal engine problems since you continue to drive it while it is over heating...

hi from uk from your symptoms and you described very well ! your problem now is the water pump impellor has either broken ? or the impellor has spun on its drive shaft resulting in there will be no flow of coolant through the engine/radiator hence o/heating of static coolant? you are very lucky! normally the damage could be much worse and expensive? you should never try to start a car with frozen coolant i have seen thismany times resulting in cambelts shearing teeth due to frozen pumps resulting in serious engine damage to valves/pistons/cyl heads however? you will have to investigate coolant circulation? and take the appropriate repair measures this is not beyond diy if you have tools/manual and patience wish you good luck please update on what you discover ? in mean time do not drive car! till fixed you risk head gasket failure due to o/heating ?

You might have a sticking thermostat. If it's sticking shut, it won't open when needed and the engine will overheat. Even though the water in the radiator is not hot then, the water in the block of the engine is boiling.
After that overflow, the cooling system was underfilled, so when the thermostat finally did open, it had plenty of room to refill, which is what you saw when the water got "suddenly sucked in".
My recommendation is to replace the thermostat (and gasket), because as a point of diagnosis, it is a relatively cheap part but can have terribly inconvenient consequences when malfunctioning. If you're handy, get a Haynes or Chilton manual from the auto parts store and do it yourself.
Also, the radiator cap is not good to mess with when the engine is hot. Doing as you did by opening it while overheated upsets the balance between the coolant in the block and radiator. There's a small rubber hose from the top corner of the radiator to a plastic (probably translucent) overflow tank on one side of your engine compartment. Under normal circumstances, you should check the coolant level there, as it exists to keep the system in balance. Note that I said "normal" - which means anytime it hasn't overheated to the point of leaking out of the radiator cap or leaking elsewhere.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck

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.
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.
