The coolant hoses, temp sensor and thermostate have been replaced.... owever the thermostat is out right now because it takes much longer to over heat with it out.
i counted the cell codes i get 4 slow and one last quick flicker....


please help asap thanks

 

ok so iv been with the car for about an hour now letting it run and the temp gauge is not buging above normal.... however the resoviour tank coolant starts to bubble up and once again this is with out the car over heating.... any ideas

 

blown headgasket

 

yup. i agree its a head gasket

 

And wats you basis for assuming such a cadastrafic failure?? please elaborate.....

further infor now that iv inspected th car.

It runs fine, drives fines, great idle motor runs and feels strong, however just today it started to over heat so he replaced the coolant hoses, coolant temp sensor( sensor located under but forward of the distributer, also the sensor located on the thermostat housing.
He did notice that when the car started to over heat, when he poped the hood (still running) the fan was not coming on so they jimmy rigged a switch to keep it on all the time.They also removed the thermostat temperarily before they found the fan issue. because it would take much longer for the car to over heat with it out.
I had the car here for a good hour and half two hours and it did no over heat at all, even holding the rpm around 3.5k it stayed at normal operating temp.
So so far it seems like The fan switch may be the issue because now that the fan can be turned on( via manual switch) it has not over heated, but this is still with the thermo out.

My last question....i cant remeber if they are supposed to have a PUSH fan or a PULL fan.OH and also the coolant inside the OverFlow( resivor tank) would begin to bubble, and the tepm was fine????
any help would be greatly appreciated, i have a project car but i really need a DD

 

The CEL code is 41, which indicates a problem in the circuit for the O2 sensor heater element.

Bubbles in the coolant suggest that the head gasket is blown, which is letting exhaust gas enter the cooling system. Not good.

 

There is not conamination in the oil, no smoke from the exhaust, spark plugs look great and have not noticed any loss in coolant........... any other input
and if you just gunna say OH its you head gasket how bout a lil explanation on why you would say that...

 

RONJ@HT
thank you for actually explaining why you would think so, and the heads up on the code.
any chance can you refer me to to how you got code 41 from just what i told you.
Iv been out the game for a lil while but am i correct ( Fore Slow Blinks equal 10+10+10+10 and then i quick would be 1 equalling 41 i couldnt remember how the equation went..... thanks

 

Correct

 

And so far every thing seems fine with the manual switch on the fan beside the bubbling in the over flow tank,
could that possibly be an effect of not having the thermostate in and so the coolant is dumping into the over flow tank, Cause i wouldnt say its really bubbling (well not Boiling bubbling for that matter just dumping in there)

 

Be concerned that you need to have the thermostat removed and the fan switch jumped in order to keep the engine from overheating. Having the thermostat removed is not the cause of the bubbles in the reservoir. My recommendation is that you not buy this car, unless the owner is almost giving it away. An engine that has overheated is likely to become a Halloween nightmare. My 2 cents.

 

we have yet to see a price, or see pics, 500 wouldnt be bad for a clean eg hatch or coupe just needing a motor.

 

I agree with ron. Overheating these engines definitely takes its toll. I would only recommend buying if you plan to do an immediate swap or make it a project car. The head gasket is blown for sure, but what problems has the overheating caused in the mean time? just be careful.

 

Well he left my house this morning and went home id say about 5 miles probley less to his house and temp only went up to half way of the entire gauge so dirctly through the middle of the coolant sign in the gauge and didnt get any hotter than that, even with continuing driving
No where near the red H so it really didnt Overheat per say just started running a little warmer than normal, because i know the gauge normaly reads just under that lil sign in the gauge. so i highly doubt there was any damadge to the motor.
But like I said I ran it For about an Hr to and HR and half ( with the fan running Normaly) and it stayed at the normal gauge position.
But Like I said The coolant wasn't boiling or anything in the resivour it was just kinda pouring in ther IE the the radiator hose.
Would that happen because of not having the thermo in causing to much coolant to just run into the engine so it would dump into the over flow..... any possibility

 

But yea it deinetly has not "really" Over Heated I.E Temp Gauge Running up to the H, the highest it got was half way and that was before the fan worked.

Of course I wouldnt buy it if it really Over heated cause i have seen the damadge that can cause i.e warped blocks, cylinder heads melted sensors etc.

He originally wanted $1200 But Im getting it for $800

Hes gunna bring it buy tommorrow and im gunna toss a new thermo in it and fix the fan switch/ relay We it may be and see what we got cause he is a friend so even if i dont buy still wanna help em out.

He also showed me a jimmy rigged Throttle Boddie coolant passage that his friend did. So were gunna throw a new TB on and also a newer IACV i have laying around.
and from wat i understand he used Half 50/50 and then Half water to fill it all up so that was def a noobie move so im gunna drain all the coolant and use the proper mixture cause i know that would def make a car run hot.

 

Oh and if it was the head gasket wouldnt i be loosing coolant???
either leaking out( in between the block and cylinder head)
Or burning it up (coolant falling into the combustion chamber) and burning out through the exhaust?? because im not loosing any.

please fellas any more suggestions

 

Using an overly weak mix won't make the engine run excessively hot. Indeed a coolant/water mix actually cools better than straight water (mind blowing, I know), but it shouldn't cause a failure like a head gasket.

What engine, how long has it done this? The difference between a D15B8 and even just an B16 would make it worth trying to fix the problem instead of just reusing the motor as a coffee table. For under $60 for a head gasket, it may be able to be fixed.

 

well i honestly belive a bad head gasket is still undetermined, but we'ed be actually talking about a 75% water to coolant ratio, however the car is being droped off tomorrow.... at his expence im goin to replace the thermostat, water pump radiator cap and fill with an apropriote mixture of coolant.
I will keep you guys posted becuase from what iv always seen if were talking about a bad headgasket there are definetly two noticible issues.

1. coolant is leaking from the matting serface of the block and head.

2. coolant is finding its way into the compustion chamber cause a sweet burning smell, along with coolant being burned out through the exhaust causing a loss in coolant and most of the time white smoke. Im expericancing neither.
If any one has any input, or an explenation on why and how you think its the head gasket please let me know it would be much appreciated.
Or any other ideas on what could be a possible issue...... Thanks

 

Oh thumper64..... hes had the car for 4 months, this just started today d16.
never got hoter than half the gauge and the coolant fan was not working, after rigging the coolant fan to run the only issue is that coolant runs into the resivor extnsivley but car does not run hot anymore.

 

If it's not a head gasket, how would there be bubbles in the coolant resevoir? Don't tell me it's the latest craze in moonshining, fermenting green liquor.

 

Forget the hatch, no matter if you buy it right now something is going to mess up later. you might have the luck and privilege to drive it right now and there wasn't too much problems with the car as of now but wait until later. Like you said, you need a DD but this ain't going to cut it because of too many mechanical problems. Get something else.

 

Compression test, and or leak down

Yeah i also agree this car doesnt sound too reliable regardless of headgasket being blown or not atnleast not dd reliable
