coolant return routing for expansion tank

[Fred Allen Burge]

Is there a problem with routing the coolant return hose (bottom hose) of an expansion tank to that plug at the bottom passenger side of an S13 radiator (not the rad drain valve, it's on the driver side)?

I'd prefer it to cutting into the lower rad hose and having to buy that expensive splice fitting they sell.

There's a plug on the bottom passenger side? I never saw one on mine.

As long as the coolant route/flow is the same, I guess you are fine.

Ya, I just noticed it today. My car is an auto and someone put in an external tranny cooler so there is a chance that it's a plugged off tranny tranny fluid passage. I'll look at it again closer.

The plug on your radiator for auto is NOT for coolant. That's the internal tranny cooler.
