This is a follow-up question to my post this week about the intake manifold on the replacement engine I am putting in my FJ45.


The replacement engine has the outlet for the heater hose on the head. My Saudi spec FJ45 has no heater. The old engine had this port plugged.

Two questions: Down the road, when I put a Vintage Air unit in this truck will I be using this heater hose fitting? Or will the Vintage Air system take coolant from another source?

Second question, until I put the Vintage Air unit in, what is the easiest way to plug this outlet? The old engine has a square head plug and it is good and stuck, will not budge. Anyone know what size plug fits in there? And what type threads? Is there a way to keep the existing hose fitting in place and cap it off?

That's more than two questions, lol, so thanks for any help.

I have several of the OEM plug for that port in stock, as well as the Air rail plugs you would want as well (someone welded the originals up on your US-spec replacement engine).
I also have several new OE hose outlets and rubber caps if you wanted to keep it, yes you would use that location later for your heater.
 
Heat and then tap the plug with a hammer. Soak it with Kroil every day for like a week. You could put on a short piece of heater hose on the barb fitting with a hose clamp, then stick a bolt in the open end with another hose clamp. You could unscrew the barb fitting so you can measure the threads and then buy a plug that will fit

Sounds like a lot of work compared to just buying the correct fitting for $13 ( including) mail from a vendor that already knows exactly what he needs. :lol:
 
I agree. Good practice removing stuck bolts/plugs for the time when the part is NLA. Then there is training for trail fixes like if a heater hose blows in the out back - a couple of spare hose clamps and some some whittled sticks and poof you are driving not walking.

Right now I can only dream of getting stuck in the outback, LOL. When I bought the truck last year it ran but it had a cracked block, so I havent really driven it except to and from a local shop. Want to get this "new" engine in, get it running and then see what I've got as far as the rest of the truck goes.

Thank for all the replies. CruiserMatt I sent you an email, thank you.
