After I drive for a while I get coolant coming out of my filler cap/weep hole on the water pump side, any idea?

 

BTW, I don't get a low coolant buzzer, but did when I was filling after the engine swap.

 

Are you talking about the weep on the water pump itself? If that is leaking, the pump shaft seal is deteriorating and the pump needs to be replaced.

 

No, I'm talking about the little tube thats comes off of the filler neck, its plastic, looks like a tube should be attached to it but there isnt.

 

if you take that filler tube off then there is an o ring between the filler tube and the raditator. you might just need to change that o ring

 

ok, this plastic tube, it the pressure cap on top of it like the one to the bottom right in the picture? If so, there should be a rubber hose going from that plastic tube to the overflow bottle. If the hose isn't there, then the coolant will just pour out when the pressure cap opens to relieve the pressure instead of being stored in the overflow bottle and sucked back into the engine when the engine cools off.

 

Yeah, it's like in picture 'J'. Damnit, I could have sworn the FSM said there wasnt anything attached. Let me go out side and see where my coolant overfill bottle hose is attached to.

 

Okay, the filler cap on TOP of my radiator is also exactly the same as the one in picture 'J', which is exactly the same as the one to the LEFT of my alternator. The one from the radiator is attached to the overfill bottle.

What am I doing wrong here? The FSM says nothing should be coming from the one by the alternator.

 

Its quite obvious that someone installed another filler neck from a different car or an aftermarket radiator with a filler cap. Thats why you have two pressure caps. Pretty damn straight forward if you ask me, but have them both going to the overflow bottle using a line splitter and clamps for the hoses. This is what I did with my car. Originally I bought a really high PSI rad cap for neck and had a stock OEM cap for the rad, that way the pressure would be released on the lower PSI (stock) cap first, and not the neck. In the end I just ran hose just in case from both to the overflow tank.

 

I had thought about that but the way I have it routed is EXACTLY like the FSM. From what I can tell the radiator is the stock calsonic one.

 

your not listening. One of those parts are not stock, the seven in stock form, well any that I have seen, NEVER had two radiator caps. Just do what I said and you'll be ok.

 

Alright man, sorry for being like that I'm just **** retentive. Thanks for the help!

 

Hey no prob, I understand, your just making sure.
