what is the quickest and simplest step by step way of replacing the thermostat and cooling fans? let me know. never attempted it.

 

The t-stat you will get to from unbolting the waterpump housing. But you will have to drain the coolant from the rad first. 3 bolts on the WP housing from what I remember.

As for the fans....Hmmm...it's been a while..Mine are upright due to the FMIC install so can't remember what stock is like now..

 

I used a manual fuel pump that I use to take gas for my rc car to take coolant out of the T-stat housing and it worked great, did not have to go under to drain thecoolant, took the IC off and the belts and replaced the T-stat...took me about 30 minutes to do...

 

Sure wish i'da thought o' dat...

 

Just jump into it....its pretty much 1 of the easiest things you could do. Just make sure ya put the thermostat in correctly. Also....flush your cooling system while youre in there. Heres a pic of the coolant drain plug that you'll need to take out to do this.

Here's a good site for you to read up on doing your own matinence on your 7.
