No not major !! Locate the upper radiator hose and follow it to the engine the thermostat is located at the connection to the engine in the metal housing that the hose is hooked to, Just remove the two bolts that hold the housing on and remove the old thermostat scrap off the old gasket and replace the thermostat and gasket also use silicone sealant on the new gasket and now re-install the housing on the engine!! Check coolant level and refill if needed ! Check for leaks if none then you are good to go!! swampratt200 AAAEEE!!!!

How do i change the heater core on a 2001 Buick century with dual side (driver's and passenger's ) controls

Replacing a heater core is almost always a major undertaking and some special tools. I wouldn't be afraid to guess that a competent mechanic would take 5hrs start to finish.
Get a couple of manuals (Chilton's) before you attempt it.

How do you replace the AC/Heater blower fan?

First check the relay. It is behind where you fill the washer fluid. take the black cowling off then remove the washer tank and there it is. We changed the fan (major undertaking) and it would work then not. After taking it apart again we discovered the relay switch. it is also way cheaper to fix

1996 Toyota Avalon. AC was only blowing hot, had it recharged now it works great unless it's really hot out then it only blows hot. Any suggestions?

Most places nowadays that recharge dont deal with older systems so I doubt they did the proper job that you expected them to. They would need to replace the AC unit and the Frion which is a fairly major undertaking.

How to fix a head gasket for 02 dodge intrepid

Do you mean replace the head gasket -- you can't fix them, you have to put in a new one. That requires removing the cylinder head(s), which requires removing the intake plenum, disconnecting the exhaust manifolds, and on the DOHC 2.7L engine, removing the timing chain -- a major undertaking. If you're asking how to do this, you probably should have a professional mechanic do it. It's not a simple job.
