Overheating Problems....
***UPDATED*** READ POST 12
Need help with this problem...
The oil temperature guage spikes to hot after driving car for about 10 mins.
Oil temperature is normal when driving on highway (maintaining a good airflow) and even AC can be used; however it spikes when driving in the city, normally goes to red after 15 mins of driving city.
No signs of overheating when guage reads hot. No steam emmitting from motor. No sign radiator cap isn't keeping pressure.
**SMALL Leak found (less tha 2mm in diameter). Leak patched.**
Coolant in reservoir low (both main and turbo reservoir); However, COOLANT LEVEL in Plastic container is above full????
[MY ANALYSIS]:
Possible air pockets and low pressure in Radiator due to small leak going unchecked. Leak patched and recommend replacing coolant and making sure there are no air pockets.
PROBLEM: Why does COOLANT LEVEL show FULL????? Both reservoirs (Main and Turbo) are not topped off....
Any suggestions? Could this possibly be a faulty thermostat? The car is an 04 WRX. Dont know if they have had any problems.

Could be a bad thermostat...if it failed closed.
Let's do the basics first.
1. Flush out your radiator. Burp the system properly.
2. Make sure all your lines are going to the correct spot.
3. Make sure you do not have any additional leaks in lines.
How exactly did you patch the radiator? I would look into replacing the radiator shortly. Those have a good history of not working in the long run.
When are you checking the level of the coolant? Hot or Cold?

I have checked levels when the car was cold.
I'm pretty sure the fans are kicking in when they have too... I can hear them, but how do you go about checking it?

Have you tried flushing your system? Might want to try that, and then refill with a good mix and some water wetter. Then, make absolutely sure that you burp it correctly.

Do you have an after market radiator or is this still the OEM one?
Do you have a filler neck on the radiator?
Is the hose that goes into the plastic over flow tank at the front of the car clogged? (check by removing and have running water flow through it)
Any recent modifications dealing with your coolant (i.e. FMIC install...etc.)?
Are you sure you didn't install the coolant return lines that go from the manifold fill area to the radiator backwards?
what's your mileage?
Have you replaced your thermostat before?
If you replaced it before did you install it correctly? Did you replace the gasket for it if you did replace it?

UPDATE:
Found out the radiator has a hairline crack and therefore is leaking. Also damaged is the thermostat.
Went to SEARS Ala Moana and they quoted $720+ for New Radiator, some hoses, a new thermostat and a full coolant flush.
Is this a good deal? Anyone can fix um for cheaper???? Let me know.
[Thanks for everyone's input.]

$180 - OEM replacement radiator
$120-$150 - Samco radiator hoses
$40 - 2 gallons of 50/50 mix green coolant
is way less than what was quoted. host an install day and labor is practically free after feeding people
if you go with OEM hoses it's even cheaper
