this is weird. i been noticing that every time i start the car, and after warm up, in the first gear, as soon as i start pressing the gas pedal, i hear the water try to make it through the pipes on the glove compartment side. and even after driving couple of miles, in the first and second gear, i also hear water try to make it through pipes. Could this be something to do with coolannt water? or air in the coolant system ? i havent done anything with the radiator or anything its 03 civic with 28k miles. please advise.

 

yah coolant flowing thru heater core.

 

i wouldn't worrie to much about it.. as long as its not leaking or overheating.. it should be a problem

 

should i do the radiator flush ? got 30k on 03 civic ? or it should go for one or two more years ?

 

you dont need to do a coolant flush until about 60 or 70 thousand

 

At least swap out the coolant, especially if its dirty, greasy, not the translucent green, or you need a different mix % for the season. Open up the cap and start the car and bubbles may come out, thats the air, then let it cool and youll have to fill it up.
Also dont run your heater until you can see on your gauge that the engine is warmed up and the thermostat has opened one time. Yeah it sucks in the cold, but it lets your car warm up faster. Deal.

 

where is the drain bolt on the engine to drain the coolant from the system. I am not talking about the radiator drain bolt. please help. its a 7th gen civic. 03

What motor? On my D16 there is a bolt on the back of the block, above the oil filter to drain the coolant. I forget the size of the bolt, but it was fairly large (maybe 19?) and you'll need a breaker bar to get it off, because it has a honda-bond type gasket sealer on it.

 

If you think something is wrong with it, take it to the dealer it's under warrenty(sp?)

Hmm.. I didn't notice that. I think the coolant change interval for the 7th gens is 60K, so I'm pretty sure yours doesn't need it. I agree if there's something wrong, go to the dealer.

 

this shouldnt be a poll. you are here to fix a problem, not take the best guess. there is a problem, and there is a solution. finding the leak may suck, but just in case, if your worried about air bubbles heres what ya do. let the engine get cold ( turn it off, wait about 4 hours i guess.) take off the radiator cap. start the car. the coolant may or may not go down into the hole in around 4 seconds. if it does, you may need more. shut the engine off, and add coolant until it comes to the top. then turn it on again, and bubbles may come to the top as if its boiling. this is getting all the air out. after a minute, put the cap back on, cause the heat will make it expand and it will go into the coolant resovoir.
remember before this to have the coolant in the resivoir to be somewhere between min and max.

also remember. coolant from the store: 50% of that coolant and 50% water to your car.
some stores sell pre-made coolant mixes, but then your paying for half water.

 

I have tried this and same thing. There were no bubbles popping up when i tried to do this procedure.

Ba Dum Da Tshhhhhh.

If you can actually HEAR the water moving through your heater core you have air in there. Take it to the stealership and have them purge it out under warranty.

 

Its actually that taco bell and pepsi combo you ate moving around as you get excited to hear your car start, i would advise you to look for the nearest gas station in prep for a restroom stop, nah j/k I would look into the possibility of air in the cooling system, either burp it or take it to the dealer to get them to clear it up under warranty

 

Sounds like airbound pipes to me. I deal with heating pipes every day, but in homes You starting your car heats the water/air, and the air expands and percolates/boils. Causes a hell of a racket in home heating pipes.

is this bad for the car ? what if i let it go like that since i dont have time to take it to the dealer ?

 

i drink coolant, and there isnt ANY PROBLEM, if you want bleed the system its not toxic... and not the most complicated thing either :shakeshead:
