I have my auto trans cooler mounted to the A/C radiator right now,but I want to remove the A/C radiator for more air flow for the motor radiator. Will it be ok to mount the trans cooler to the motor radiator or will the trans cooler get to hot.
I would recommend getting the A/C discharged before removing the condenser. There won't be a problem mounting the cooler to the radiator, automatic transmissions run hotter than the motor so it will take away the heat.
A buddy of mine mounted his against the grill bars so it's flush with the grill, not touching anything... It doesnt look TOO bad because he has a winch, but its a matter of opinion, your "safe" putting it flush with your radiator, lol your tranny fluid used to run INTO the bottom of the radiator so your definatly still going to be doing better then you were...
While I wouldn't recommend it, It'd be ok to mount it directly to the engine radiator, no issues.
Make sure to keep the cooling lines routed through the heat exchanger in the engine radiator, before the aux. cooler. Water/coolant conducts heat better than air, so your best cooling is done by the exchanger.
