would it be okay if this is your first mod? Or should you have a CAI and exhaust before you do this?

i was told that if i just get the 180* t-stat that it could make my fuel richen and set off my service engine soon because the computer thinks it still needs 195* to turn the fans on and **** or something.

This is what an autozone employee told me.

Not true. There is no SES tied to the T-Stat or the fans at lower temperatures.

When driving around the engine will be fine. The only problems will come if you drive in stop and go traffic or have the car not moving whiel the engine is running. The fans wont turn on at the correct temp and the engine will run hotter then it should. But it wont hurt anything nore will it set off and SES lights. If you ran a 160* thermostate then you woudl get a SES light for engine not heating up fast enough.

Follow the top radiator hose to the engine. The hose connect to the T-Stat housing. You will need a 10mm socket and extension.

okay i bought a superstat from autozone which is just a chromed out version of the oem 180*.
my engine is hot so i gotta let it cool off(how long does this usually take)????

Also i dont have a hose clamp remover thingajigger. Do i have to take the hose off?? cuz the hose looks like it is connected to a metal piece which has 2 bolts which looks like it might be the T-stat, so cant i just remove that metal piece and just plug in the new t-stat?
