overheating

[Wire4001]

ok guys i know how to fill the coolant levels so yeah its not the weeper or me lol. anyway i have replaced the waterpump, and thermostat and still its overheating. I am coming up with i either have a bad head or a cracked block because bubbles continue lightly coming out of the radiator and if i put the rad cap on it overheats after about 20 minutes. Any idea's or are my suspicions pretty much on par with what you guys think?

Does your cooling fan work?

Does both your radiator hoses have pressure?

Did you bleed the system?

Check to see if there is any damage to your hoses, that's what happened to mine...

To add to the above mentioned tests, pressure test the cooling system and perform a leak down test. Until then, things are just speculation.

what ^^^ said...

small bubbles in the coolant isn't necessarily a sign of anything... I had those, changed out my entire cooling system still overheated every now and then, and was about to get a HG job done when I decided to do compression/leak down test, & had the mechanic do a block test... in the end it turned out to be that I had a faulty radiator cap & that the bubbles were from air getting in and circulating through the system.

start with the easy things first... f you are going to replace parts change the thermostat radiator cap first... also inspect your radiator for ANY leaks

thanks guys, i checked and double checked. so i had a shop do a leak down and it was fine the sensor its self was what was bad the air was from a hose note quite tight enough
