M50 heater core deleted coolant routing

[Enriquez2000]

With this project the heater core is gone and thats ok. Im trying to figure out the proper way to route coolant without it though. My waterpump is already fitted with AN ports for the rafiator.

Will something like this work?

Red is delete
Green is keep
Blue is where Id plug

Yeah that's it.

Various sources for blockoff plates for the back of the head, but they're easy to make out of a flat piece of aluminum.

Then cut/plug or replace the reservoir hose, plug the TB cooler port on the head.

Lucky for me I took the intake off and back port was already plugged. So need the m12 plug... 1.5 pitch didnt thread so must be 1.75.

Found some injector issues while I was in there. Now to figure out which of the 3 rail lines go where!

Can I eliminate the line at back of the waterpump and run a traditional overflow tank off of a chase bays filler neck?

I honestly have no idea if that port can be deleted or if it needs to be able to draw for the pump/be able to push air to the reservoir to bleed properly, etc., but it sounds interesting.

I see a pic on their site of an LS swapped e30 where it's attached to the radiator (but the radiator is lower/smaller, so it might not clear the hood if you try this with a regular BMW rad?)
I also see a pic of it welded to a 24v thermostat housing, which is an interesting idea if it doesn't create any clearance issues.

I'm not sure how their tank works with a nipple on the rad and the filler neck. Might need to blockoff the radiator overflow port or else the system won't generate pressure.

It might be best to use a bmw tank off the back port in that case. Hard to tell what will clear without it in hand...

I plan on using their tucked radiator for cooling.

Also not sure if there's any issue deleting the expansion tank in general, like what happens if you don't have it, how much typical volume changes between off/cold running/hot running and if not being able to absorb that volume delta causes any issue

Makes sense. Other cars I use a different expansion style tank but like you said that back port may be an issue. You could really use any type of expansion tank on any car if you know the volume needed.
