I have searched a lot and tried a bunch of fixes but still having somewhat of a problem. First i was overheating to 260 degrees and i got a new radiator (just an oem one) and now i run at 210 degrees around town. When i get on the highway at around 80mph and get into boost the temperature slowly steadily rises to 220-230 degrees. I have no leaks of coolant dripping anywhere, i have a mishmoto thermostat, my fan is on all the time, i just replaced my headgasket (but i do have blow by from the piston to wall clearance being a little too big), i got all the air out of the coolant i think. Also the motor takes hours to cool down and seems to heat up too quick, like i get up to 180 degrees in less then 3 minutes. Any help would be much appriciated, thanks

 

Pics please. its more than likely an airflow issue or heatsoak issue. whats the setup? is the dp wrapped? is manifodl wrapped? def need pics

 

nothing is wrapped except for the feed line. i cant really take pics right now but i do break up after about 8psi and does it sound like i might be running lean?

 

No wrap + ebay fan = overheat in 90% of cases.

You probably have no fan shroud either, which cuts cooling capacity of the rad by a thrid. If its an ebay fan, not a name-brand like SPAL, it's real flow rating is probably half of what they told you.

 

and if its breaking up then you should be letting out o it, is the car tuned?

sounds like a combination of really high underhood temps with por air flow and shitty fan plus running lean will really heat things up quick and kil that motor

 

no im using the stock big fan with the shroud. and if its breaking up it should be letting out what? o?

 

and i pulled the spark plugs and theres some oil on them and there pretty black so i dont think im running lean

 

LOL

I love it how quickly people reply and hammer ebay stuff.

It is all the same shyht!

I buy stuff all the time, I even got a EBAY alum rad and fan, works fine!
