Title: Capacity of Rad Blowers on MCI 5
Post by: glenncc on May 29, 2010, 04:03:13 PM
Does anyone know the CFM rating of the Radiator cooling blowers on a MCI 5?
Thanks Glenn

I don't have that number right in the palm of my hand but I will check my manual and give it to you by morning.

Been visiting a friend in the hospital (75 miles away) all day and I'm really too tired to do any research.

Perhaps Fred Ward or one of the other loyal 5 drivers will come up with it first...but trust me ...you will get the answer you need.

 Sorry but I don't see any info on the CFM in my parts or maintenance manuals.   :(

I've never seen that number, but it's fairly high, they blow up a storm back there!

Carl, it won't move past 180 anywhere around here, there are no 5 mile long 5% grades to climb...  Also, it was moderate in temp yesterday, compared to 90 - 100 degree days.  Your cooling issues will come on climbing long grades in hot weather, with the combination of the higher power from the turbo actually getting used for a stretch of time.  Congrats on getting it out, btw.  I finally got the sedan door installed a few weekends ago!

As I recall you have the stock 5C rads, blowers, but a hydraulic motor for the blowers.  You might consider a mister, since I really think that unless you are really on the throttle your cooling system will be able to keep up.

My 5 also runs right around 180. If it starts climbing above that i start letting off of the throttle a little or downshifting my 644 to keep the rpms up around 1750-1800 to get maximum cooling effect. The  most important gauges to me are the temp and tach,.....speedo is third. :)
