Thread: cold water line for turbo

where the best place to take the coolant feed (cold side) for the turbo?

On a DE-T I would tap the coolant housings.

Or if you have the factory coolant lines to the tb, you can just take those off the tb and re route them to the turbo. You can tee into the heater hoses. Or you can buy the custom steel pices and use those which is pretty much like therealnighthog said minus the drilling and tapping.

ok right now im using the heaterhose for the hot water to return from the turbo....but im havin the feeling that im feeding the turbo with hot water...i just looking for a coldwater feed.

The temparature differential from 'hot coolant' to 'cool coolant' isn't really significant. Even 200* coolant is pretty refreshing to a turbo that's been blowing 1200*+ exhaust gas.

Yeah i was just gonna say that. there are 2 heater hoses you can use both of those one for (hot) and one for (cold) as you put it, or do the same with the 2 throttle body lines. You really dont need them on the tb.

I really dont understand why people tap the heater hoses. I know its easy but you add 6 additional hose clamps which are all failure points. Plus you have to run the hoses all the way to the heater hoses.

It takes 15 minutes to drill and tap the housing and you have a leak proof fitting that is less cluttered, has less failure points, and the hoses are easier to route.

^^ Honestly i think its because ppl dont want to deal with the hassle of taking their stock engine out to tap it, aka laziness. To do a DE-T setup right, IMHO, you've gotta drill and tap. There's no other way.

you dont have to pull the motor out. I am talking about the housings that connect to the radiator hoses in the front of the motor. 3 bolts on each to remove.

the heater is strickly hot water....how water in & hot water out. it only give out cool water when the heater is on.
