Manifold coolant pipe??

Post by Rusty260 » Sat Feb 21, 2009 2:02 pm

Finally reassembling my L26 to go back in the car after a clean up and paint

Does anybody have any idea why coolant water is run thru the intake manifolds?

On the three engines I have i notice that the steel pipe between the manifolds is rusted thru, the water to them has been disconnected

Is there any point in me trying to track down some 10mm o/d pipe to replaced this rusted pipe and connect it back up again?

I believe it is to keep things warm and avoid the fuel/air mix separating out and condensing on the manifold walls. Unless you're skidding around in ice and snow I don't think it makes much difference whether you have it connected or not in NZs climate.

My L28 has an old S30 carb manifold on it, and i haven't bothered to hook up the water. I think it just helps vapourise the A/F better in cold conditions, and make it run a bit better when its cold. As for me I just warm up my Z before I take it out so its not a problem for me. Also the exhaust headers are directly below the intake manifold on the L engine, so they tend to keep it warm newayz (more so than I'd like I think :) )

Pull it apart anyway and find out how it works!

I have taken the pipes out while the manifold was off, one less thing to have too repair!!

We'll look forward to seeing the 260 back on the road, as when we saw you last time it was in your ute at the Car Colors night. :wink:
