1G Need the hose sizes for back of thermostat housing

[enriquez2000]

I am installing my billet housing when I drain my coolant. Id like to put in aluminum fittings but I dont know the hose sizes to orderer the right ones.

I believe one is 5/8 but the other is smaller. Just need a confirmation

Do you mean the throttle body feed? If so, it's for 3/8 or 10mm hose.

I dont have anything to throttle body anymore but I believe it was that yes.

Is the other 5/8?

Is the other 5/8?

Yes, 5/8 should tightly fit. Or 3/4 should loosely fit. It's like in between.

Thank you!

We should have a list like we do for bolts for hose sizes
