Ok so heres the story.
I buy an LS about 2 weeks ago, installed myself, and it ran "ok". For a while i had idle problems, like at a stop sign, it would idle from 3000 to 2500, then back to 3000 again. O yea it also had a little sputter (put put sound). I dunno why it did this. Newho i thought it would stop after running it in for a while.

2 weeks later the sputter didnt stop (sputtering doesnt mind me, but maybe i did something wrong?) and the idle went down to a consistant 2000.

Ok so im on my way home, merging from the 5 freeway to the 22 sloped on-ramp in traffic.. My car is idling at 3000??? Wtf? Tried putting it in 1st gear w/o gas to see if it would move... it did not. Neway so im driving, and then all of a sudden my the temperature skyrockets. I pull over and pop the hood.

What i see is my overflowtank squirting lots of coolant from underneath it? or somewhere down there. I check for fluids coming out the hoses but i didnt see anything at all. Inside the tank was massive pressure and hot coolant. I open the radiator cap and there goes a massive coolant explosion. So i fill her up, used a whole bottle of rad fluid (rad was almost completely empty) and got home. Idles at 1500 now... seems normal.

Will it stay like this? Should i be expecting the same problems in the next few weeks? Ne1 know whats going on here?

again i did not see any radiator leaks from hoses...

 

sounds like u had a big air bubble in your coolant.

 

if that was the case, everything should be okay now?
I took my moms car to work today :]

 

just remember to start your car with the cap off for about 5 sec then put back you cap on...

 

you sure you didnt crack the radiator? You should top it off and bleed the system if necessary.

 

before i think the radiator was leaking, so what i did was buy that NO LEAK crap, and the radiator was fine... for a while i guess

If it IS the radiator, HMOTORS screwed me over again. The first one they gave me was completely broken, it was like i poured radiator fluid thru a big *** straw.

And so i had to go there to replace it. I guess it was nice of them to replace it free of charge, but the valley is so far from me.

Radiator coolant is not cheap my friends! I have probably spent about 20 dollars on it already for those 2 radiators... blah. Water is my new frend.

 

Ok today on my way to school car was idling around 3000 RPM. I have no clue what it is.... Someone please help me... friends say vacuum lines, iavc, pvc, blah blah, but dont know how to check it.

Someone outthere help!!! i think also that becuz its idling so high its wasting and burning alot of my coolant in the radiator? Any advice out there?

 

are you throwing any CEL( Check Engine Light)

 

yeah the engine check light is on but thats cuz the 02 sensors arent connected, thats the code it throws

 

bump

 

well then check your o2sensor and knock sensor..

 

o2 sensor doesnt connect to nething... its weird... prolly cuz engine is obd1, with obd2 wiring meaning thers an extra plug? i dunno..

neway help pplz bumppp

 

your headgasket is bad.

check your compression and stop driving the damn car.

 

no idea about the 3k ideal. but there should be big bubbles inside the rad. top off the cap, let it run for 5 mins, fill it up and close the cap..

 

hmm... how do i check the compression?

 

bump

 

ok so i fixed the idle... it was my throttle body cable, it was set on too tight haha

heres a pic of my dirty *** coolant stained engine bay

camera phone is only 10% accurate of its dirtyness... believe me

 

Bleed your coolant system to make sure coolant is actually going through the radiator. Does your fan turn on?

There should be a bleeder valve right by the head and the block on the left (pass) side. Let the car run for 10-15 mins with the bleeder open and you should see bubbles come out and keep doing that until you see a full stream, then close the bleeder and then fill the radiator.

Also dont use water, water = rust inside the block. Anti Freeze = prevents rust.
