I wasn't sure where to post this, so I figured the newb forum was a safe bet. Now, as a precursor, I am a seasoned DSMer and I have read a lot before posting, so please let's keep this thread helpful. Thanks!
I've been struggling with coolant temp issues now for a while. I attempted to make some heat shields and some different fan combinations, but it still would run hot. Not necessarily overheat though.
So I got a new OEM thermostat, put two 12" slim fans on (don't know what cfm rating), filled with 50/50 coolant/water and a bottle of water wetter. Left the cap off and ran to temp, had the thermostat open and close twice with the heater on full blast and squeezed the lower hose to get all the air out. Put a new mishimoto rad cap on and let it cool down. Then I started it back up once it was cool to operating temp. It went between 196 and 200. Took it for a spin and it would get up to 203 and back down to 196. Then after 5-10 minutes of driving it went to 213, back down to 206, 203, then back up to 216! Headed home and it got up to 219 at its hottest. Both fans on full.
I'm not sure what the problem is, but I do have a concern about my o2 dump tube. I have a FP3150 with a tial 44 on the side and a dump tube that lays basically right over the downpipe. Unfortunately with the fan shroud, this tube is touching the back of the one fan on the driver's side. I checked when I got in the garage and both fans still worked. Nothing was melted.
Lastly, here is some basic info on the car (instead of checking out my profile info)
2g with a 6 bolt bottom end (maybe 5k miles), new rebuilt 7 bolt head
FP 3150 turbo w/ tial 44 and o2 dump
Punishment aluminum rad with fan shroud and 2 slim fans wired together to go full on, or just off
FP 2.5" o2 housing, 3" exhaust
ECMLink v2
I don't know what my next move should be here. Any suggestions/thoughts?
