my car -b18c 93 civic cx
parts car -b17 civic 92

Took the rad out of my civic parts car to switch it into my civic. Noticed there are 2 lines on the rad - where the hose is cut and beside the bleeder -
(hose was already cut by previous, and no line to other outlet)

What are they for? I dont't have them on my civic's rad. Power Steering?

 

For an automatic. Oil cooler or something to that effect. You can remove those fittings altogether if you have a manual.

 

Yes i have a manual. The parts car was converted from auto to manual. i just wasn't sure if i could just remove the fittings and the rad not leak fluid when i installed it.

So just remove them and all will be well? i don't need to plug them?

 

Nope. I don't have them installed on my hatch when we replaced our radiator. No coolant flows through there. If you want to make sure for piece of mind. take one off while the car is just sitting.

 

Grumble is correct. That is an internal transmission oil cooler for AT's which is separate from the coolant within the radiator. Just leave them be if you don't need to use them.

 

Appreciate the help. Thanks guys.
