Car Forum / Honda Cars / July 2006civic engine heating up ???
hello, i've got an older civic and today noticed that the engine was heating up going up to H, got to a gas station and stopped and noticed that there was no coolant......bought some coolant and this seemed to help. Everytime i am cruising it is fine it is when i stop at a light it creeps up and when i accelerate that it creeps up for a bit. Does it take some time for the coolant to make it everywhere and work? After adding the coolant i have about a 5 mile ride home and it was still acting funny. any ideas? > hello, > [quoted text clipped - 7 lines] > > any ideas? fill to the top, then look for bubbles in the fluid when the engine's running. suspect blown head gasket. >> hello, >> [quoted text clipped - 10 lines] > fill to the top, then look for bubbles in the fluid when the engine's > running. suspect blown head gasket. so if there are bubbles the head gasket is blown? is this something hard to replace??? a price? can i drive a 200 mile trip without a head gasket? thanks for any and all advice >>> hello, >>> [quoted text clipped - 12 lines] > > so if there are bubbles the head gasket is blown? 'fraid so. assuming the systems not just expelling air block. fill it completely, run it till hot, and watch for continued bubbling. > is this something hard to > replace??? it's a huge pita, not so much for the strip-down but the prep for the new gasket. > a price? you're looking at $500+ to have someone else do it. call around for quotes. parts are cheap, it's all labor. > can i drive a 200 mile trip without a head gasket? if it's boiling inside 5 miles, /definitely/ not!!!! > thanks for any and all advice It may be something at simple as a sticky thermostat. I'd start by replacing it > >> hello, > >> [quoted text clipped - 15 lines] > > thanks for any and all advice > hello, > [quoted text clipped - 7 lines] > > any ideas? --------------------------------- Top up the reservoir to MAX and check it when the engine is cold. Keep topping it up until it stops 'sipping' from the reservoir when it cools. It may just be displacing AIR which has gotten in, (unless you've truly screwed up you engine).

If it's not working, you can run the heater on high to keep the engine cool enough. > hello, > [quoted text clipped - 7 lines] > > any ideas? Sounds like a malfunctioning radiator fan. Prolonged overheating will get you into deep doo doo... JT > hello, > [quoted text clipped - 7 lines] > > any ideas? When you added coolant to the radiator did you open the bleeder valve for the coolant system first? If you did not do this, then there will likely be trapped air in the system which could be causing your continuing problems. Wait until the engine is cool, open the bleeder valve, and then top up the cooling system closing the bleeder valve only after there's nothing but coolant coming out of it, i.e., no air bubbles. What that said, the question remains as to why your cooling system was so low to begin with. Is there a leak? Common problems are a leaking water pump or a bad connection at a hose fitting. Less common is a bad radiator but Honda used a rubber o-ring to seal the radiator drain plug and sometimes these go bad. If the leak isn't obvious and you can't find it, then you may have to get your system pressure tested. Eric hello i've got an older civic and today noticed that the engine was heating u going up to H, got to a gas station and stopped and noticed that there wa no coolant......bought some coolant and this seemed to help. Everytime i a cruising it is fine it is when i stop at a light it creeps up and when accelerate that it creeps up for a bit. Does it take some time for th coolant to make it everywhere and work? After adding the coolant i hav about a 5 mile ride home and it was still acting funny any ideas Ron check your basics first like: -does the cooling fan come on when the engine is hot -have you changed the thermostat -is the rad and resevoir full -can you see any leaks -do you find yourself adding coollant regularly -- johnin 94 Civic, same problem, cause was blown head gasket. Cost $800. Do not drive it like that. G-Man > hello, > [quoted text clipped - 7 lines] > > any ideas? Should there be coolant in the radiator?? If I open up the radiator cap and there is none should I add? - when should there be coolant in there...when the car is hot, cold, etc? > 94 Civic, same problem, cause was blown head gasket.

There should always be coolant in the radiator, all the way to the top. If there is not, not only does coolant have to be added, but if it is disappearing every week the leak needs to be found and fixed. Of course, don't open the radiator when the engine is hot or even very warm. A couple years ago I did that because the radiator wasn't very warm and scalded my arm pretty badly. Learn from my stupid mistake. Mike |
