Were to buy 180 therma & how to remove clutch fan?
 
Have 09 ram 5.7 want to buy a good 180 deg thema and want to remove the clutch fan for more power, how to remove ? Thanks

You can order/get a 180 deg thermostats from your local parts store. Since you're removing the clutch fan are you getting an electric fan to replace it? Which are you looking at going with?

Thinking of doing the same to my truck, let me know how it goes...

I'm with the other guys above. Get a good themostat at a auto parts store.
Most of 2009 Ram's don't have a belt driven "clutch" fan but do have an electric fan mounted behind the radiator.
The waterpump, a/c compressor, alternator, etc are driven by a serpintine belt. Apparently the R/T's have a viscous cooling fan.

I found a couple of pages in the 2009 Ram service manual that might help you out.

Good Luck!

Doh! I hate when this happens, but I have to correct myself!
I looked under the hood a little more today and I noticed that my 5.7L Hemi
has a belt driven "clutch" fan buried under the radiator shroud. I knew better but after looking at
the service manual I assumed it wasn't there. I know the electric fan is there cause I here it kick in now and then.

Although I'm almost always right (just ask my wife...haha) as much as I hate to say it, I stand corrected.
Really, when is the last time you saw a V-8 without a clutch type fan? What was I thinkin????

Lol, it's ok Airdog.

I'd recommend one of the Flex-a-lite fans if you want to install another fan. If you want to lose the fan shroud and stock fluid bottles, talk to Moe at Moe's performance, he does a delete kit for the HEMIs. Picked one up for my '07 and it looks great. Also has the 180 deg thermostat option with the kit. Just an idea.

Not to thread hijack but, what is the purpose of switching to a 180 degree thermostat? What degree thermostat is in there now? :4-dontknow:

CdnoilRAM 11-22-2009 06:45 PM

Switching will open the solenoid sooner (@180deg) and keeps the coolant and engine block at a cooler temperature so you have less parasitic heat loss. A cooler engine is a happy engine... to a point, as they're designed to run at a certain temp range for oil lube and metal expansion seal. I believe the stock therms are 196? correct me if I'm wrong though.

If it's that much better, why doesn't Dodge just put them in at the factory? There has to be a reason why the engineers decided to use a 196 degree thermostat:4-dontknow:

Keep in mind that it is possible for a code to set in the PCM for the coolant not reaching operating temp fast enough.
