Default WoHo Tranny Cooler is in. But ques. about the thermostat

Man, The tranny cooler was alot easier than I thought it was gonna be to install. I only had to go back out to get a couple fittings. This is the first real mechanical type thing I did to my car so far and I'm loving it.
Now that that'* taken care of, I'm gonna go ahead and but the 180 thermostat in. But on which side of the radiator is the plug to drain the coolant? I know I gotta remove the plactic cover, but is there anything else in the way? Also, can I just drain a little coolant out or do I have to let it all come out?

Thanks everyone for the confidence and know how to do the tranny cooler!!!

If you're just changing the t-stat, you don't need to drain the radiator.
Remember you'll need the tstat, the rubber o ring and a new gasket, which I had to go to the dealer for because no one in town had one.
A little coolant will run out of the hose, but if you keep it up above the radiator level you won't lose much.
When I change them, I just top off the system, start the engine w/out the radiator cap, keep topping it off, let the engine idle until the tstat opens, and top it off again.
After the tstat opened on mine, I loosened the brass screw on top and coolant ran out, so I figured it was bleed.
The only reason you would want to drain the radiator is if you're going to change the coolant.

Alright, I have all the parts waiting for me. I wasn't sure exactly how much coolant would come out when I unbolted the hose. Keeping the hose above the radiator does make sence. Maybe I'll back my car up onto those ramps cause then the hose will definatly be above the radiator... just have to keep the car from rolling since the emergency brake is in the back... ok thanks hopefully i'll have that sucker in there by the weekend.

I really wouldn't worry about it. You're only going to lose a quart or so. If you put the back of the car up on ramps, more coolant will run out of the tstat hole when you pop the stat out, and that would drain out of the block. I would just keep the car level. If you're worried about what you spill, a bucket or two of water thrown down on the spill would dilute it to where you couldn't tell it'* coolant.

Yep, the tranny cooler is easy . I had my doubts at first but after starting those doubts were quickly put to rest. You really don't need any special tools unless you want to run some metal hoses cause then you have to bend them. All that'* necessary is a flat head, a razor, and a wrench.
You also don't have to worry about anything spilling if you tap into the line at the top of the radiator. BUT :o don't just start to try to but it all together right out of the box. Take a look at all the fittings, sizes and quatity, to make sure everything will hook up. Also, save the hooking up iot the lines for last. This made it alot easier for me.

Paulnold -if your car is a SSEi you should have a tranny cooler already. I may be wrong, but it should be located in front of the radiator and ac condensor at the passenger side just behind the bumper. It is very obvious if looking for it and there is one there from the factory.
If that'* the case adding another tranny cooler may not be as hard putting a first one in. Just run a line from the outlet of the first cooler to the inlet of the second, and then run a line from the outlet of the second to the original tranny fluid return line. Also, don't forget to secure the second (or any cooler you put in whether first, second, or third if you are running ALOT of power to the trans).

Stylez
