Tranny cooler mounting

[quantum500]

I have a large hayden oil cooler that fits nicely on the drivers side engine bay door.  I was wondering what others have done to mount one.  Its on a MC-8.  I have what I think is a really good idea but maybe somebody has a cheaper easier idea.  My idea is to use some 2" pipe that is split with a rubber cushion to hold the cooler weld some angle on it.  Bolt these pieces on the door so they will accept each side of the cooler.  Depending on my measuring abilities if the tension is not adequate I will add some all thread between the mounts so I can adjust tension.  Pretty simply and cheap, but I always like to see other ideas that my be cheaper/better.

We installed our Hayden cooler on the passenger side to maintain an easy access to the electrical panel on the drivers side. We added a couple strips of SS at the top and bottom of the door on the inside to attach the cooler to. We installed the cooler from the outside to the strips of SS using clips.  Jack

I was thinking about something like that too.  I'm using some long hoses with 90 degree fittings on the cooler so when it swings out it will pull the hoses out of the way of the electric panel.  Do you have a pic of the finished look from out side?  How many degrees in temp drop did you get out of it?

[JackConrad]

We noticed a drop of about 10 degrees in all temps (water, oil, & tranemission).  That is without even running the fan, this from natural air flow through the cooler from the OEM blowers.  Jack

Cool looks nice, I'm looking forward to getting it in there and testing it out.  Thanks for the help Jack!

If you look at the bottom of Jacks mudflap you'll see a strip of rope lighting lol, one of many lol.  I heard a rumor that when jack fires up the lighting on his bus the space shuttle can read by it lol.

Jack,

Is your cooler before your rad heat exchanger or after?  10 degrees is a lot and I can't imagine any not picking up on this.  You Hayden looks like a Air Cod condenser.

Thanks,

John

John,
    The plumbing is as follows: 1" hydraulic hose from cooler output on the transmission to the top of the Hayden transmission cooler I installed in the side door.  From the bottom of the Hayden cooler, a 1" hydraulic hose goes to the inlet on the OEM cooler on the side of the 8V71. From the OEM cooler outlet, a 1" hydraulic hose goes to the cooler inlet on the transmission.
   Theoretically, if it reduces the transmission fluid temp to less than the engine  coolantwater temp, the fluid would actually remove heat from the engine coolant when it passes through the OEM cooler (I have no idea if this happens). This routing of the transmission fluid does allow the engine coolant to improve transmission fluid warm up when starting
    I dont remember the Hayden model number but as you can see if pretty much fills the door opening.  I purchased it on Ebay.  Jack

Jack,

I was wondering if you had the ability to "warm" the trans fluid and it seems you do have.

The other side of you comment about the trans fluid absorbing heat is this....being cooler, the trans fluid "does not" heat the rad coolant.  You have soooo many pluses going for you in this and there is not a down side I can see.  I know the original setup was "adequate" and all that but these systems are tired in many ways and a little help is all some of them need. 

I will keep an eye out for a Hayden cooler.  I am also considering a multi pass AC heat exchanger as the total area of the pass is well over 1 inch.  May need tig work on the inlet and outlet. Just thinking out loud a little.

I understood you to say that you had a 10 degree drop in tx temp.  What was the temp drop across the aux cooler you installed?  Easy access from the outside was a nice break.

Thanks,

John

I installed my cooler today and it turned out great.  I still have a couple of things to finish but as of right now it can go down the road.  I used my idea with four mounts that clamp the cooler with a rubber cushion.  The hoses swing out out of the way to access the electric panel.  I need to put the air cleaner housing back in and see how everything works.  I'm really happy with the way it turned out so far.

John,
   I have not checked that.  It may be difficult to check that since I usually do not even run the fan on the aux cooler, but rely on air flow from the OEM blowers for air flow through the cooler. If I open the door to shoot the temps, I no longer have the air flow through the cooler and when running, I have the CFM from the engine running at about 1800-1900 RPM.
   I guess I could measure the temps with the cooler fan running (3000 CFM) and get a "ball park" figure.  I will try to do that the next time we are out. I will try to remember to test after a long drive, just before shutting down.  Jack

If your getting a reduction of 10 degrees across the board the difference should be more from top to bottom.  It will be interesting to see what you find, although difficult to get a good measurement.
