Yes, you can do it with minimal tools. First though, please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Here is the procedure for your car:

  1. Disconnect the negative battery cable.
  2. Drain the coolant.
  3. Remove the air intake duct.
  4. Disconnect the radiator hose
  5. Remove the thermostat housing.
  6. Remove the thermostat.
  7. Clean all sealing surfaces.

Hello Friend:

The cost of a Thermastat is under 15.00,And its very easy to replace.

#1) Just open Hood and you'll see your Top radiator Hose take your hand and follow it down to the Engine.this is where you'll see a Hose Clamp, Its holding the Hose on YOUR THERMASTAT Housing,Remove Clamp and Hose and .

Where the hose was attched you'll see a Dome Shaped Housing.This is the Thermastat housing,Just remove the Bots holding it to the Engine.Underneath you'll se your Thermastat.

Remove it and Clean up both Surfaces to Housing and Engine.When you purchase your new Thermastat some have a New Gasket if Not ask fir the Thermastat Housing Gasket Also.

Just apply some Gasket Sealer to Both Surfaces (Thermastat Housing and Engine Surface.Put on the Gasket lining up your bolt Holes and Tighten down to 1=18-21 Ft, lbs or Tighten all bolts very Snug DO NOT Over Tighten You'll strip the Bolt Holes.

Put your Hose back on Clamp it good and Tight, Replace any Coolant to Full Level===Your Done .

Whatever is causing the timing adjust itself at the wrong time. It could be anything from a vacuum leak, to a coolant sensor to electrical problem. By reading all the LIVE READINGS from the sensors & getting an emissions reading will help u narrow down the problem. It doesn't sound like a DIY fix. Equipment needed

Ii have a 2000 Cadillac deville. My question is


Probably the best thing is a Glass shop. It sounds like a part called a window regulator is broke. Hopefully the cracking sound is just the plastic of the regulator and not electricity arcing.
In trying to do this yourself, the window has to be up and braced. Your Cadillac is a big car with big windows. Parts are a little heavier and harder to control.
You can call around for the price, tell them you "WANT TO KNOW THE COST OF REPLACING A WINDOW REGULATOR FOR YOUR CADILLAC DHS."
