i installed a trans cooler on my 94 z28 and i bypassed the line into the radiator for the factory trans cooler and the open line drips little drops on the ground from fluid still stuck in the line. i tried to glue a bolt in the hole but still found a way to seep out. anyone have any ideas as what to use to plug up the end of the line. thanks Jeff

 

Blow the fluid out of the lines with compressed air.

Put a fence at the top of the cliff instead of an ambulance at the bottom.

 

don't have a air compresser-

 

Use your biological one. Extend it with a piece of rubber hose if it doesn't reach.

 

alright i will try that thanks

 

When you hooked-up the cooler; did you simply re-route the lines that normally go to the radiator and run them to the cooler instead? Are the nipples on the radiator what's leaking now?

If so, there's a better way .
Run the pressurized cooler line (from the tranny) to the cooler, then from the outlet of the cooler into the radiator where the pressurized line used to connect.
This serves two purposes: Extra capacity, and it keeps the tranny oil from getting too cold since the radiator will heat the fluid if the cooler overcools it (like on a cold day). The tranny likes warm fluid, if the fluid becomes too cold, it doesn't flow as well thru the tranny. Slow fluid flow inside the tranny will cause increased wear due to slippage during shifting.
