Overheating issues...blurping is not working......need help doing test.
OK, ive been having some overheating issues forever.
And me trying to do the blurping has not yielded great results.
To some things up quickly i got a hole in my radiator back in April and the car overheated......i was able to cool the car off and top it off to go home.
Later i pulled the radiator got the hole fixed and started the long process of blurping the system......after several different methods i have not had any success getting the air out.
Methods tried: Front of car jacked up, Rear of car jacked up, Front of car jacked up with Spill free funnel, Rear of car jacked up with Spill free funnel, front of car jacked up releasing the rear valve when cool, and rear of car jacked up releaseing the rear valve when cool
So now i assume i have a leak and i can't find it(dont see any coolant) or i have a bad headgasket......i have checked my bottom radiator hose after warm up and the hoses is just as hot as the top so i assume the thermostat is good
I got a compression test from a friend but i have no idea how to get my car to TDC to do the test.
Can anyone explain how to get my car to TDC to do a compression test
If the compression test doesn't show any results then i will trying a coolant pressure test then ima give up and send the car to a shop so it can be someone else problem

Also a friend said smell the exhaust after a good heat-up........if i smelled a sweet smell at shut off then - Bad Headgasket
But when i tried i didnt smell anything
and i also checked the oil to see if any coolant was visible also......no luck there

Thanks but this seems like another method.
to my understanding i do not have to have a remote start and i am only supoosed to remove the spark plugs.
I was told to find the position where my number 1 cylinder is at TDC and plug the tester to the number one cylinder then apply pressure

You sure your water pump hasn't gone out?
You can also check the oil to see if you have coolant in it. Will be a milky color/texture. Or you could take the car to a shop and have the vacuum the coolant system. This will be sure to rid any air that is in it. If it is still overheating then you can look for something else.
How long are you spending when you try to burp the system? I know when I do it, I use the spill free funnel. It usually takes about an hour to do it. I let it get hot until its about to boil over, stop it. Let it pull back in the coolant. Start it again, do the same. Then I let the coolant get cool (let it sit for 30 mins if not longer) Do it all again. Just continuously watch the fluid inside the spill free funnel. It may seem like the bubbles have stopped, then a few minutes later you'll get a big chunk of them. You'll also be able to see when the thermostat kicks on by the amount of bubbles. Also, the fans will cause more. Just a very long process from my experience. Others may have better tips. Also, make sure you are turning your heat on (no AC) full blast inside the car to help speed things up.
Like I said, I am not sure how long you have spent trying to burp it, but it takes quite a long time to get it completely out if you do it that method.

do you even know what test you are wanting to do????
A leakdown used TDC, while a compression is exactly as the article described.
maybe you should figure out what you are really tryin to do before you ask questions

Breather tank
I have installed a breather tank and it has allowed somewhat better
removal of air bubbles.The breather tank is installed at a higher height
than the top of the radiator.Mine is about 6 or 7 inch higher.Most of the time
I sqeeze the upper and lower rad hoses and burp the bubbles into the tank.

Over heating
If you pull the sparkplugs , I could be wrong but dont they leave a white
deposit on the plugs if the coolant is leaking into the cylinders.

Vaccum system.......check (I'll try this if the these test doesn't yield any results)
I spent two 6hour days blurping the system and I allowed it to cool for an 45min before opening the system.
Oh an yes i did have the heat on full blast during the blurping sessions
You arent the only person that says that my thermostat can still be crapping out......is it possible for the problem to be intermittent?

1. blurp 93 up, 27 down
to get pulled over by the police. comes from the sound the police sirens make ("BLURP!")
2. Blurp 7 up, 7 down
Verb. The act of burping then blowing it at someone.
3. blurp 11 up, 17 down
when your computer freezes but you keep clicking and when it unfreezes everything happens all at once

It's your head gaskets. Their blown and air gets into the cooling system when the motor is running thus overheating. Take the cap off the radiator with the motor running idling and you should see bubbles coming up.
Look for water vapor in the exhaust. White water vapor/cloud.

The best way I found to "burp" the coolant system if to open the plastic screw on the passenger side near the throttle body. With the car running and the heat on high, open this and have towels or rags (not good ones) under it. Coolant will bubble out. Do this until your heat feels really hot. If you have air in the system, chances are your heat blows cold or neutral air while sitting at idle.

I did a coolant pressure check to see if i had any leaks and it seems my system is good (NO LEAKS)
Then i did a compression test, but the motor was cold, when i did so I got these numbers
172, 165, 175, 180, 170, & 160 (psi)
Whats the range for good cylinders?
The spark plugs do have a bit of white deposit but its the same on all of them
SOON
I will be taking a probe to each cylinder to look inside and will do the leakdown test
