I'm thinking about using a stock depth cast aluminum pan on a 2004R. I don't want a deep pan because of clearance under the car. Hot Rod did a side by side test and found the aluminum pan dropped the fluid temps about 10 degrees. Has anyone here used one or have a comment?
What Larry said. I fitted a deeper pan and it's still not the lowest thing under the car. Adds fluid capacity and it all helps cooling. Oh and it no longer leaks! I also junked the supplied paper gasket for a Moroso one. The B&M pan I used also has a temp gauge port. Cheers Bob
I’ve got a larger cast alum pan than stock on my 2004R but it isn’t too deep or low hanging. I don’t have any good pics of it but it’s been reliable.
I have a pan from Hughes Performance. Ground clearance is about 41/2" w/ empty car. I guess that once I have headers installed, they will have less ground clearance. Don't know about the temperature, as I have no temp. gauge installed and on top have a separate oil cooler. Hope that helps.
That does hang down a bit low I’m not sure if I would like that. I will have to check the height of my pan.
I would worry about a big bump cracking the aluminum, then the fluid is soon gone. Steel more likely just gets bent. I spend my money on super duty (cooler) 4 row radiators. good luck, Bruce Roe
Lately have had to order my big 4 row radiators as near custom brass and copper, no aluminum here as I could not do any work on one. The internal coolant to trans fluid cooler is all I use. An external trans cooler is another way to increase the total capacity, but at the the cost of temperature controls, possible rubber hoses leaking, more stuff I manage to do without. Sometimes a modest front radiator fan has been used, primarily to help when sitting idling (esp with air cond), or to continue to aid cool down after shut down. Not for on road use. good luck, Bruce Roe
