thermostat replacement

[LikeNew02]

Hi Guys,

My car is overheating and I am pretty sure that I have a stuck thermostat. Can you guys answer a couple questions about replacing the thermostat.

Does anybody have replacement instructions that they can upload?

How long does the job take?

I found these instructions online but I was hoping for some my details and pictures. "If you have a V8 you must first take the cover off of the motor. Then with a 5/16 socket take the entire ac tubing off starting from the intake on the upper left hand corner of the motor. Then right up under the container labeled torque remove the screws with the 5/16 socket and a 3/4 extension be careful not to stripp the screws. If water start to drain a little thats okay. You should hear a little air escape due to the pressure coming off of the thermostat."

thanks in advance.

Well I'm not sure about the process, I had it done at a shop. The thermostat sticks either open or closed, can't remember which. If you want the part for cheap, go to the Team Ford Parts banner on the right side of this page.

Those are terrible instructions. Go here first, to figure out how to drain the coolant. That's your first step:

Here's a pic showing where your thermostat is. It's the second hose down from the engine fill cap (labeled degas bottle on the picture). 3 bolts and that's it. Can't remember if you need the gasket or not. If there is one, make sure you replace that as well. If you need to, you can remove the intake tube to make everything easier to access. disconnect the tube from the airbox and throttle body, remove all electrical connections from intake tube, and remove tube. :

Holy Sh*t!

I called a local dealership(Hayward Ford) for a quote to change my thermostat. The service guy said that it required the removal of the air intake.

4 Hours labor + parts = $700 +

I will call one more dealer ship for a quote. If is much more than $300, I will likely do it myself.

thanks for your help

Dude... this takes less than an hour. The book that the garage uses says you have to remove the intake manifold. No idea why it says that. You do NOT need to pull the intake manifold to change the tstat.

However, if you are skeptical of doing it yourself, you probably are better off paying someone to do it. FYI it cost me I think about 30 bucks when I did it myself. Could've been less. I can't remember the price fo the tstat/gasket

Took me 45 minutes to do, whoever said it took 4 hours must've been doing it with 1 arm... and on drugs.

extremely easy to do. And you may need to perform the bleed procedure several times to get 100% of the air bubbles out of the system. Otherwise, you may get random overheating situations. Just watch the guage...if it begins to creep 3/4 or higher...put the heat on full blast for 30 seconds or so. That usually dislodges the air bubble.

thank you

thanks for everyones help.The thermostat change was easy.

I wonder if the dealship really would have taken my $700? It only cost me $40!

I am not sure if I did the air bleed correctly because I could not find any of the values. But it doesn't over heat anymore.

THANKS AGAIN!
