Default Blown Head Gasket

How do you check for a blown head gasket? I am having a cooling problem and think I have a blown head gasket.
Will a compression test show if you have a bad gasket?

Whats the cooling problem your having? If you have water in the oil, or if your losing water with no signs of a leak, you may have a head gasket problem.

It starting overheating all at once. I have checked the TS and replaced the water pump. I do not see any signs of water in the oil but I am losing water with no leaks.
How can I tell which side is bad or leaking?

You could get a coolant pressure tester and apply pressure to the system and see if any of the cyc fill up. Check spark plugs for corrosion or coolant tint to the plug. They also make a kit to check for combustion leaks.

Do they make a tester that tells me what side is leaking? Thanks for the info. I guess this tool would tell me if I have a blown head gasket.

You ever figure it out? My car stated to do the same thing yesterday, over heating out of no where, with no sigh of a leak. I checked the oil on the dipstick and it was clear like new oil, which I expected since I did an oil change 3 weeks ago.

The high boiling point of coolant is partly due to the fact that it is under pressure. If you leave it running with the radiator cap off it will boil over. I do not think that is your only issue though as you are over heating when not removing heat from your coolant ( via the heater ).
Makes me wonder if your fans are kicking on? Check that first.

IF the you put a 165 stat in the car and you did not have the pcm retuned to have the fan settings come on earlier, your cars fans will never come on to cool the fluid in the radiator. How ever you are doing minimal cooling having the blower motor cool off the fluid coming thur the heater core. Put a stock thermostat back in the car. (2) 10mm bolts and see if you are still having the same problem'

Those fans should come on regardless of thermostat, I think it's around 225 and the off by 215. If you swapped the radiators (regardless of how much we try) then there WILL be air in the cooling system. Hot air expands, blah blah blah. How many times has the engine completely warmed up and how times have you topped off the radiator and reservoir after an overnight cooling? Squeezing top radiator hose helps air bubbles come out, so does rocking the chassis.

in regards to what I posted above. I definitely am not the most knowledgeable person about this subject, and legitimately appreciate being intelligently corrected.
