Help with constant overheating.

[B-Boy DuB-L]

I have been dealing with overheating issues for a long time now. It first was the thermostat then the upper rad hose leaked and the next morning my radiator sprung a leak as well. Now since i replaced all of it i have been getting a lot of air inside it. About every week depending on how much i drive my car begins to overheat. It is collecting air from somewhere but there is no leak anywhere. I always bleed it until there is no air. Once it starts overheating again i go to bleed it and there is as much air as the first time i bled it.I need suggestions on why this might be

[sebazztard]

hm.. radiator cap maybe?

[Hoffman5982]

water pump? mine used to constantly overheat and i replaced the thermostat and water pump and it ran fine

im very sorry to tell u, but it sounds like a blown head gasket... same thing happend 2 me, was driving and steam built up and cracked my radiator, and later found out that steam built up cuz of a blown head gasket...

does the temp go up and down? or just straight up goes to H... wat king of thermostat did u put in, i would suggest nissan or nismo

I agree it overheated and ran dry. You keep getting air pockets after bleeding the air out. I also say headgasket.

Check the obvious. Is the exhaust steaming or smell sweet? Drail the oil is it milky looking with a green tint? pull the plus does one or two look dirty / oxidized?

based on the symptoms you provided i think it may be a head gasket problem, I cut the following from Wikipedia.

If the gasket fails, a variety of problems can occur, from compression loss (leading to power reduction, or a rough engine), to exhaust gases being forced into the cooling system, leading to the engine overheating and increased engine wear due to the motor oil being mixed with antifreeze.

Well when the overheating first started i thought it was a blown headgasket but i had 170psi across the board. It is only overheating because it keeps collecting air. I have no clue why the engine keeps collecting air, even after i bleed it. Its not the water pump, and its not leaking from the seep hole either.

[B-Boy DuB-L]

Yea im worried about the headgasket but the thing is there is no sweet smell from the exhaust and i just did an oil change and the oil was not milky and did not have a green tint to it. it was basically perfect

[OutToWinPAHC]

It might not be blow into the CC, but sounds to still be blown. Could be a side leak. Id check compression again both dry and wet.

along with checking your oil, check your coolant to see if there is oil in it... if it is a blown head gasket, save a lot and do it yourself... get the gasket KIT from FRsport.com and a water pump also just to be safe... itll only cost u about $130 for both items, cant beat that, its better that $1600 for the same job from somewhere else

try and hope for the problem to be small, check your rad cap and even if it doesnt look bad, CHANGE IT!... try to bleed from both bleeder bolt and radiator it self, get a no spill funnel to keep it more clean... run it for like an hour doing this w/ the heater on full blast...

you want to check to see if the thermostat is opening, bubbles are coming out, and if it still overheats just while idling and sitting still, its probably a blown head gasket

[B-Boy DuB-L]

it doesn't overheat after i bleed the air out of it. It only does it after about a week of driving. And its prolly like 70miles give or take.

[OutToWinPAHC]

If you do replace the gasket take the head to the machine shop after cleaning it. Have them inspect it for warpage and cracks. It usually runs 40-45 and another 35-40 if they need to mill it down.

[capblueberry]

does it do it more when your sittin in traffic ideling alot?

could be that ur auxilary cooling fan that cuts on when no airing is going threw the engine is locked up and need a new one.

happened to me.

[B-Boy DuB-L]

nah only when im driving. Say im driving and it starts rising once i stop moving it will stay at wherever it is

[S13xCrazy]

oh man, headgaskets are so easy for me now.I can do em in less than an hour and a half no problem.

The first time took a while, but from then on its smooth as butter. If you need help, hit me up

[Scisserhands]

Same thing was happening to mine. But along with that, my temp gauge wasn't reading right, my radiator blew a hole through the top plastic part, and for some reason the damn thing was idling around 4000 rpm. Its out of commission now, it got too hot and now the head's f***ed. And I had just put a new clutch in it at that. I'd replace the head gasket before anything worse happens.

Ok well now y car wont even turn over. It started and it was like sputtering a little bit. So i decided to give it some gas, once i did that the rpms dropped dramatically and once i let go of gas it would rise back up, well i pressed on gas and the car stalled. Now the car won't even turn over. So this is screwing me over because i can't check the compression. Any ideas?

your engine is probably flooded with coolant b cause of a blown head gasket

[B-Boy DuB-L]

Well i got the car started but only by push starting it. It squeeled until i pressed on the gas to 3k rpm. I let it sit for awhile and it was running perfect. Then it started sputtering again. So i tried pressing on gas and it bogged. So i realized when i only press a little bit it would rise in rpm fine but as soon as i pressed harder it would bog. Then after a couple of minutes of that it stalled!!! I was thinkning i should check my plugs, maf, oxygen sensor?, fuel injectors?

Have you tried puling codes?

[24j0hn]

Have you tried puling codes?

i agree... try getting codes... this may be a retarted question to some but its serious, is your oil level to the H? cuz ka engines are hydraulic so if the oil is low the pressure is low so itll sputter all nasty of wont even start!!!

[B-Boy DuB-L]

honestly ive never checked my codes b4. Maybe i should do that. And i just did an oil change in my car, and it is at the H so im safe there

[OutToWinPAHC]

Yeah dude try pulling codes and see what happens from there.

[B-Boy DuB-L]

Well guys today i pulled my codes. I got the great code of 55. Which means nothing is throwing any codes. And i checked it in mode 1 while enigne was on and the light was off so thats good to. I'm going to start with the basics. im gunna check compression spark and fuel along with my maf

Another thing to check if all else pan out is the CAT itself incase the effers clogged

[sebazztard]

sorry to thread jack, but (outtowinpahc)i found some vids of your car on youtube last night, AMAZING lol. i hope to get my project rolling like that.

[OutToWinPAHC]

Oh thanks man

[B-Boy DuB-L]

What would the symptoms of a clogged CAT be?

[OutToWinPAHC]

Burning hot manifold, almost red looking. Rough idle, stalling, and running hot, and affects the EGR
