Ill make it short... basically the ECTS is snapped but it still fits so i just stuck it in there temporarily.. i changed my waterpump and tstat like 2 months ago, everything was fine..

like a week ago i turn on the car, feels funny and i saw the coolant backpressured to the reservoir tank??? so it moved from the rad to the reservoir. i moved it back and it was ok.

3 days later, the car had a lot of trouble starting, cranks all day but doesnt start, and very weird noises, next thing i notice, overheats like crazy....

i turn it off, then for the last 2 days, everytime i turn it on when its very cold, it'll just warm up and like 3 minutes later, overheats like crazy even tho the rad is full and reservoir is perfect

the codes i have are 0707 0908 0103 1005 0705

so mainly EGR valvue, ECTS?

im going to sell the car ASAP and going for an 06 g35s so jump in if you have any prior knowledge or experience..

guys come on.. i need help =/

egr has nothing to do with overheating. Change out that ECTS and it should solve your problem.

scmaxima

u think thats the only problem??

check your thermostat it might of stuck closed

scmaxima

ok, ill get right on the tstat.. and hmm i doubt that a bad ects would cause all of this.. the car overheats and the radiator smokes !!

the fans might not be kicking in do to the bad ects

youd be surprised how much trouble a bad ECTS can cause. I had it go in my car before. I know

stamar

um blown head gasket

look at the oil for mud

ummm, yeah, head gasket is a good possibility. but, check your oil first, and your rad fluid.

iTrader: (3)

yeah, man. make sure the fans come on and go buy a new sensor, it's less expensive than dealing with a blown hg. Also check your t-stat.

cashoit

check tstat and eCTS. SOmetimes tstat cant be installed backwards.

How do you know it is overheating of the coolant temp sensor is broken?

scmaxima

ok look, its not a blown head gasket, the oil is fine! its not the fans too because they both work as soon as i turn the ac on.

The ects is snapped off but i put it back in place, yes ill change that, and u think all of this can be from a bad tstat?

scmaxima

bump..

if it's stuck closed, then yes. it doesn't allow the coolant to cool your engine.

BlackMax1997

When did the overheating start? If a month passed after the wp and tstat were replaced, then it's not likely that the tstat was installed in reverse or that there's a problem with it. If the ECTS got snapped right before the issue started, then that's likely the problem. Are you sure you purged all the air out of the system after you replaced the other parts? You could have an air pocket that has moved to a position that is causing the issue.

^^true that. bleed the system when the car is cold by opening the radiator cap and looking for bubbles getting to the top of the filler neck. Wait till the level starts rising. Once that's done, just put the cap back on.

BlackMax1997

If you do this, it would probably be a good idea to elevate the front of the car to allow the air to move towards the front of the system. Let it run with the radiator cap off until the level rises. Also, have you replaced the radiator cap? That's something that is often overlooked, but needs to be done as well.

scmaxima

hmm funny thing now =/ i just checked it again and the problem is still there... i found that the engine burned some oil tho so i filled it up. BUT the radiator keeps drinking the antifreeze real fast! i just let it cool down to find that AGAIN the reservoir is empty, and the radiator is half empty 0.o the car overheats from an entire night of being shut off in bout 4 minutes after turning it on

whats the problem there guys

find where your coolant is going! might be your water pump.
also check your oil for coolant contamination.

BlackMax1997

OP, have you tried pulling your tstat out and running the car temporarily without it? I know the tstat is only like 2 mos. old, but it's possible that it could have had some sort of a defect. Also, have you flushed your radiator? You may need to do that and check the flow out the bottom to see if its adequate. You could have trash buildup in the bottom of your radiator that is causing an inadequate flow problem.

Blown head gasket from the combustion chamber to the cooling system. Whats pushing the coolant out is combustion chamber gasses. Get a mechanic with a sniffer to verify that you have exhaust gases in your cooling system.

BlackMax1997

On a more serious note, IF it is a head gasket, the coolant could be leaking into an exhaust port and burning off. You would be able to tell if your car is putting a lot of steam out of the exhaust and if your cooling system pressures up really quickly. After I've had a chance to think about the symptoms your car is having, a blown head gasket is not so far fetched...

FallenOne

iTrader: (17)

Well.. First off be sure the hoses have pressure and that your exhaust isn't whitefrom burning coolant.

Have you made sure your radiator isn't cracked? Mine was and ate coolant like mad... Also it ended up ghosting a erg and knock sensor code as well as an O2 due to it slightly overheating.

scmaxima

hmm thing is.. the coolant just dissapears.... i dont think its going in the engine cause the oil is perfectly yellow/brown. but idk =/ the ECTS is completely broken, and hmm radiator gets realllllly hot, even the pipes. in literally no time so yea.. im really clueless guys and i cant move the car because i can risk burning the engine even just to go to the mechanic

scmaxima

well i doubt its cracked because i dont see any coolant on the floor at all.. and the reason i think it has pressure is that when the car is warm, i touch the pipe its very hard and hot so im assuming it has pressure. oh and the rad cap is new 2, so its not loosing pressure

BlackMax1997

If you have a blown head gasket, coolant doesn't automatically go into your oil. If the gasket is blown at an exhaust port location, the coolant will vaporize and go out the exhaust, and you will have exhaust gases in your coolant system.

I didn't see coolant either. It was a pressure leak, a hairline crack. Was a pain in my ***. Basically.... I had to warm the car up, throw a zip tie on the tb to hold a higher rpm and look for the crack... Figures it was right up top. Fragile brittle pieces of crap.

i Had the same problem its a blown headgasket man trust me its very fustrating

scmaxima

how can i fix it temporarily at least till i sell the car? or there isnt any way =/

98Maximo

I scrapped a VW passat due to slight rod knock. When my mechanic recommended that I put a very thick oil and treatment to hide the noise and sell the vehicle, I dropped him. Donated the car instead.

I fu*king hate thieves.

+1 here...

Either fix it right, or sell it AS IS - telling them that it needs a head gasket.

Well, if the coolant "disappears" really quickly and it's not dripping/leaking......it's pretty obvious. It's a blown headgasket. When it's cool out, look at your exhaust coming out the pipe. Is it white?

Since the car gets hot really fast, it sounds like you didn't install the thermostat correctly...

No, there's no temp fix for this. And shame on you for mentioning passing the buck to the next buyer.

scmaxima

ok so now i figured... im gonna fix it and sell it. or just put it up AS IS with the problems listed...


but still, i dont know if its really a headgasket, i dont smell anything wrong in the exhaust except the rich smell of gas that ive been smelling since day one, and thats why i get like 11 MPG lol

could it be anything else other than the tstat or ECTS?

cashoit

YUP!!

iTrader: (7)

You get 11 MPG because you live in NYC, Traffic here is horrible, if you haven't changed your tstat maybe you should do so.
