Default Trans cooler mounting position - HELP!

I'm currently in the process of mounting a b&m 70264 supercooler. The instructions are worthless, can somebody help me out:

1)Is there a designated inlet and outlet for this cooler?

2)Does the cooler have to be mounted with the two fittings facing upwards?

3)Is it a bad idea to use the zip ties to mount the cooler?

4)The bottom line coming off of the radiator is the return line correct?

Thanks!

1) it doesn't matter which one you use as inlet or outlet
2)One fitting should be above the other fitting; and the fitting to use as the inlet should be one you place at the bottom.
3) there is a B&M (or any other brand) cooler mounting kit that you can buy with proper cooler attachment ties.
4) if you live in a hot climate state you're better off to bypass the radiator altogether.

The reason why I was asking about the orientation of the cooler was because every picture I've seen with the plate-style cooler shows the two fittings facing upwards.

The cooler came with the mounting kit, is this what you're referring to? I was concerned running anything through the condenser. Has anyone developed leaks doing this?

I live in MinneSNOWta . The bottom line is the return correct?

bump. Just want to make sure its ok to mount the plate-style cooler sideways. And that the bottom line is the return line.

Heat rises. On most cars, the car radiator has its inlet at the top while cooled water exits at the bottom of the radiator.

Personally, I mount the trans oil cooler with the inlet at the top with the outlet flow at the bottom, just like most radiators. Whether it makes a significant difference or a slight difference I cannot say.

Accessibility is also a factor in how one mounts the cooler.

Funny, I always thought / believed it was generally speaking the oppisite.....hot fluid in at the bottom, and cooler fluid out at the top........believed this was generally done to assure all air is out of the cooling system

I don't mean to beat this to death but:

1)The botton line coming out of the radiator is the return line correct?

2)I've mounted the tube and fin style coolers in many different ways as it really doesn't matter as the fluid must follow the same path regardless if its right-side-up, side-ways, upside-down....
With the plate style cooler 100% of the photos I've seen have the fittings facing up....which always seems to be the most inconvenient position. I'm assuming that with the plate-style coolers the fitting MUST face up? Again, B&M makes no mention of the correct orientation...I'll never buy another B&M product.

The top/upper line coming out of the radiator is the return line to the transmission - this is the line that is connected to the cooler. If you start your car cold and let it warm up, you will begin to feel the temperature difference between the out flow and return transmission lines. The return will be noticably cooler to the touch - its the upper line.

I don't think it matters how the cooler is oriented - I mounted mine in front of the condensor with the inlets facing up - this made it easier to bring the line around the side of the radiator to the return line.

The kit should have come with long zip tie type fasteners that you push through the radiator & condensor fins and finally through the cooler bracket hole before to install the retainer. Cut off any excess fastener that sticks out after the retainer is slid on. The hardest part is getting them pushed through the radiator/ condensor fins so they will align with the holes in the cooler bracket.

The fittings I received with my kit did not fit the radiator inlet so I just cut the return line from the radiator and attached the cooler hoses to it.

With the inlets of the cooler facing up, you can poor trans fluid into the one of the hoses until it tops off in the other. This would probably work just as well with inlets facing to the side. If the inlets face down you won't be able to get the air out. Then connect the hoses to the trans return line and you won't lose the cooler fluid volume of your trans fluid level.

I haven't checked the vette but on other vehicles you can hold the hose going to the top inlet of the radiator in your hand after you start the car and it will be cool until the thermostat opens and coolant begins to flow out of the motor. I believe the flow goes out the top of the motor to the top of the radiator so air can flow up and out of the motor without having to go against the flow of the coolant fluid. It just travels with the coolant to the high spot of the radiator.

I owned a chrylser product that had a bleeder fitting on top of the thermostat housing to let trapped air out or the cooling system would get a vapor lock after a coolant change and over heat - ask me how I know this.

You're right, I was wrong........had a brain fart...........I was thinking of the flow of transmission fluid thru the radiator, which I do believe is from bottom to top.
