Well I've been driving my 5.3 swapped s10 around the past couple days and haven't been having any problems til tonight. 5.3 has the stock truck waterpump with the stock theromostat that I have not replaced. I'm using the 4.3 s10 radiator which is used.
The radiator is holding pressure I know that for sure...

Now ever since I've started the truck I've never had water in the top radiator hose but never had a problem with overheating until tonight...

Just wondering what could be causing the top radiator hose to get any water...

Did you fill the engine through the top radiator hose? If not, pull the top hose off, fill it, put it back on and then top off the radiator. You have an air pocket.

I dont remember if i filled it through the top or not, so i'll do that tonight or tomorrow! Just to make sure, how many gallons or whatever do you think it will take? Just trying to make sure I get it close...

Thanks!

I think it should be ~3-4 gallons depending on how much your radiator takes.
