Radiator Issues! :-[, Keeps burning/losing coolant Options

[JoKeRkId613]

Okay, here's my situation:
1. Blew my OEM radiator(cracked)
2. Temporarily replaced with a Honda radiator
3. Just put in Koyo radiator(looks just like the factory one, just brand new)

-I bought a crap load of coolant.
-First thing I did when all hoses were connected and the car was off(which i think was a mistake...there was no coolant in the radiator at all...it was flushed) was that i poured in coolant until the radiator filled to the top.
-I put the radiator cap on.
-The car hasn't overheated at all.

Currently, I'm running without the radiator cap because I was told I was supposed to have the car on and let it reach a certain temperature before i poured in the coolant. So I'm letting the car take in as much coolant and then refilling so it circulated correctly.

QUESTION:
What shoulda been the proper way to do this from the start? My car still steams every once in a while and it loses coolant a lot and i have to refill. HELP PLEASE!
I have a new thermostat, perhaps I should change it? How is this done...anyone got pics?

replacing the thermostat is easy. You should of done it when you had the hoses off and the radiartor empty. To change the thermostat, follow the lower hose from the radiator to the motor. That connects to the thermostat housing. 2 bolts hold it on. You can see the bolts from the driver's side of the car. 10mm or 12mm I can't remember. Unbolt, replace thermo and gasket, bolt on. Since you already filled the system, coolant will spill everywhere (easier to do it when it's empty)

puke tank is slang for the refill tank which is to the right of the radiator. I'm glad you figured out what LOW and FULL mean, I didn't want to slap you upside the head , yes you fill the coolant in there. Just check it after driving a while, then in the morning when it is cold. Fill if it needs it.
