its now summer and here in vegas with an easy 110 degrees.

my car is starting to have a slight overheating problem.
used to be able to run vegas drift courses all day without a problem.
now it just overheats after one run.
during daily driving after a while, the temp gauge will peak at half way, sometimes climb and then drop.

i'm running 2x 12inch electric fans and 3inch aluminum radiator.
i already changed the thermostat and pressure cap.
im running 50/50 mix with water wetter.

still has fluxes in temperature.
i know the temp sensor isn't giving false readings cause my coolant boils into the overflow sometimes.

i dunno what else to look for.
does the system need to be bled??
could unaligned banjo fittings on the coolant lines on the turbo cause this? (pulled the turbo once)

Bump. no one's got any ideas??

Fan shroud and cooling panel just to make your cooling system that much more efficient? Replacing your coolant?

yeah get the stock fan shroud and fan clutch installed asap

Geezy · 07-15-2010, 04:37 PM

i understand that much about the stock clutch fan and shroud, but what doesn't make sense is that i never had this problem before.

i ran a vegas drift even in February during the day at 90+ degrees and it didn't overheat.
then i ran an event last month at night which was like 90 also and i would over heat after one run.

ok now what oil are you running? my friends at boso run water with coolant not 50/50

Geezy · 07-15-2010, 05:10 PM

im running mobile 1 10w40. running a little thicker for the summer. winter months i use 10w30.

Bleed the system again since you said you popped the turbo line off. Might have some air in there and you not realize it.

*fliprayzin240sx* · 07-16-2010, 04:02 AM

And 10-40W is still too thin in my opinion considering how hot your car runs.

Geezy · 07-16-2010, 04:54 AM

well, it didnt run this hot before, so i figured 10w40 would be good enough. i check the oil at least twice a week. im thinkin of takin it to tire works and gettin a good flush and system pressure check. only 20 bucks. and i guess i'll check the banjo fitting before then too.
