Where should the 2.4L coolant supply to the turbo be located?

Where is it in an SRT-4? Where is best to add to a non SRT Stratus 2.4L?

Looks like there must be boss on the back side of the block. low and around the first cylinder so the coolant is cooler. Same location as the 2.2/2.5 block.
dont have one myself to look at though.

Yep, coolant feed is from the back of the block in about the same area as a 2.2/2.5. I don't know if there is an appropriate area in a NA block though.

There is a tap on the back of the block... the pipe going into the water pump came with a tap on it too.

I was going to use the water pump pipe from the radiator as the feed and port on the back of the block as the return, or is that backwards?

The fitting at the back of the block is for the oil filter cooler adapter, mine was teed off the heater hose.

I don't have an oil filter cooler or a heater hose...

Backwards. The normal flow of coolant is from the back of the block and back into the head on a 2.2 or back into the pump on a 2.4.

Actually, I lied. After I posted that it made no sense, both of those are outlets, you'd be getting coolant pushing it's way from both directions rather than flowing through. So I looked more carefully and the srt-4 returns to the t-stat housing as well. I don't know what you're planning on running for the t-stat housing, but it looks like you'll need a return.

Cool, gotta have a Kustom t-stat housing so it should not be an issue :thumb:

Dont need any flow at all, turbos cool by convection.

Just plumb a good non cavitated coolant to the bottom
of the turbo, the turbo boils the water and is naturaly
pressurised and pushed up into head where it returns
to the radiator via the t-stat.

So would one port on the back of the block and one on the t-stat housing (located stock area by #1) be prefered?

btw:


convection n.
2. Physics
a. Heat transfer in a gas or liquid by the circulation of currents from one region to another.

Perfect routing, and yes the turbo acts as the pump to circulate
the fluid :) Hey you gotta come up in a week or two, final assembly
starting and you may like some little twists Im throwing in ;)

Nope, it'll be more fun seeing the look on peoples faces when drag
day rolls around at SDAC18 :wow1: Kinda glad I didnt jam it togehter
and show up this year untuned and not track tested like I usualy do.

You know, if I did it myself, I'd probably be able to answer this one for you, lol. I know I have coolant plumbed for my turbo on my 2.4L, I just don't know how it's routed. Car's still in the shop and I've been out of state on business.

Would a 1/4" ID return line back to the head be too small?

Thats not much smaller than the factory cars ran, they were
setup for grocery duty and quick trips so I cant imagine why
not. Your gonna let it cool down than mom did back then.
