Keep getting conflicting results while searching on the size/thread/pitch of the coolant ports.

They are either 14x1.5 or 16x1.5.

Anyone know for sure before I shell out 20$+ on AN fittings?

Thanks.

 

test it by turning a bolt in it.

so y ou never ever have to ask this question again

 

Yes, I can take a caliper and measure, but that won't tell me if the thread pitch is correct (1.5) or anything else for that matter.

The turbo is relatively common, I am surprised I can't find the info while googling or searching here on HMT.

 

you probly wont find the info here because nobody really runs the coolant lines to the turbo

 

IIRC the 50trim (saab/volvo) turbos usually had metric fittings, and most fords used NPT fittings. Your best bet is to get it measured at some bolt place like Fastenal. They can usually get you whatever threaded item you need afterwards too.

 

If it's a standard garrett water cooled center, they're 1/2" NPT.

 

For searching purposes.

They are 3/8 NPT. Fastenal to the rescue.

 

Leave them open and call it done, not worth the hassle to hook them up. The amount of cooling they do is minuscule at best. It's just another line that can possibly leak.
