I have a 91 thunderbird 5.0 going in a 93 fox and an upper intake off of an explorer and it seems a coolant passage has nowhere to go. What should I do?

Thread 'Whats the center intake hole for?'

Jan 19, 2004
i noticed when i changed my fuel injectors, and had my upper intake off..

thats theres the 8 Runners, and a smaller hole in the center? and my GT40 intake had a runner for it and it loops around to where the throttle body connects.... but, whoever owned it before me, put a 1"? spacer in there. and the spacer blocked off that center hole. i ended up putting the spacer back in on the reinstall. but im curious

what does this do? anything worth while?

i found a picture of a trickflow heat spacer. but this one DOES have the center hole that im talking about. here

That's not a coolant hole, you have missed matched upper & lower intakes, the lower is from the first gen intake, the upper is a later gen intake, internal EGR and external EGR ?
If the emissions have been removed just put a freeze plug in it and move on.

Yup. You have a mismatched intake. Early explorer lower with later non-EGR upper.

You pretty much need to delete the EGR, and block the EGR port either at the head, or by drilling/tapping the hole and inserting a plug.

If you want to retain the EGR, you'll need to find another upper.
