My son has a 91 honda civic. He hit a possum and cracked the bottom of the radiator. We replaced the radiator, the water pump went out. We replaced the water pump, and the themostat at the same time. Now the problem is that it still overheats. 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. 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. There is also white smoke coming out of the tailpipe. Any help PLEASE.

Replying to: rrumba (Mar 03, 2007 8:35 pm) If that is the problem, the reason the water is boiling out is because due to the head gasket blown, coolant is seeping into the cylinders and that is getting burned off through the exhaust, but in return as the cylinders move up and down, you will get air forced back into the cooling system as a result of the cylinder movement. Since the air takes up volume as well, and since you're probably not making even trade with coolant/air in the head, the coolant has no where to go and will come out of the overflow bottle. That is what happened with my situation. I would get overheating as well. Also I don't know where you live and if you use the heat at all right now, but I was losing that as well since there was so much air in the system it was getting trapped in the heater core. After typing all this and reading your message again I didn't notice you mentioned white smoke. Classic sign of a blown head gasket. Good luck!

My daughter overheated her 2003 Honda Civic and I had the head thoroughly rebuilt. Now that I am basically finished replacingthe head / completing the job a honda dealer tells me that if you overheat a civic and pull the head the piston rings will collaspe and the car will start burning oil in appx 2000 miles. Any thoughts from anybody out there. The car has 40000 miles on it. Overheating due to a messed up radiator throat. Water boiling out through overflow.

Replying to: aaronr121 (Mar 16, 2007 5:04 am) Anyways, I have a 95 Civic EX, 1.6. I drove from my buddies house back home which is a about a 3 hour drive, was pushing the car kinda hard. When I got off the freeway and finally stopped the temp gauge went into the red zone. 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. When we pressed down on the throttle, the liquid would fly out of the radiator, when the cap was off. Not sure if this is normal. He ended up pouring buckets and buckets of water till the foamy crap coming out of the radiator was mostly watery looking...white/clear foam. Pretty sure the radiator fan doesn't turn on anymore. I'll have to check on that tomorrow. I bought a thermostat, bought antifreeze, just trying to figure out where I should start since I really don't have much money to work with. One more thing, might be a completely different thing, but the car idles really weird now, mainly idles at about 1000 rpm's, then jumps up to about 1500 after driving on the freeway for a bit. Any suggestions are greatly appreciated.
