NED Forester OEM oil cooler kit
 

Is anyone that is using this kit have any problems with leaking from the coolant line going into the throttle body loop? I just installed my kit today and the lines were too big for the throttle body nipples, but I just got some worm clamps and tightened it as far as I could go. however, there is still a little bit of play at the connection. I'm assuming since the coolant going through it isn't super high pressure that there shouldn't be any problems with leaking, but I just wanted to confirm. I observed it while burping my coolant and there were no obvious leaks. Hopefully it stays that way.

Use some adjustible radiator hose clamps. like this. https://www.2wheelpartssupply.com/sa...FRAwaQod7oIA5g

also you can get reducers from 1/2 to 3/8 and such to get her down to the correct size, don't forget additional clamps. All this is super easy to find at your local autoparts store. IIRC plastic or metal reduces are only around $2 or so...

If you get some good clamps, they will still chew up the hose but you'll be able to get it to not leak.
