i read that post. i understand the concept but still dont understand the way our cooling system works. this thing has more crap than any other car ive worked on before. most have 2 hoses to and from the radiator and to and from the heater core. ours had hoses and fittings all over the da*m place.

why couldnt you block the heater core intake at the crossover tube on the front of the engine, route the passenger head to intake for the core and tie the core out to the drivers side head and run it in to the upper hose? i don't know where the flow out of the heater core goes.

Our heater core is routed like this. From the crossover tube on the front of the engine, to the heater core, then the heater core return runs between the lower intake and the block into the back of the WP.

Here is a pic of the heater core return line:

im really starting to think the engineers were either drunk or on vacation when they pushed this cars design through. could you plumb the ps side to the intake of the heater core and tie the output of the ds side to the core output and push it through that tube back to the water pump? just trying to see of i can cut down on the number of hoses.

Punctuation is your friend, but this ^^^^ is how most of the 4Vs & 2Vs work.
coolant leaves the rear of the pass head, to the HC and the the return from the HC goes under the intake to the back of the water pump.

After reviewing the MM engine cooling system, I always wondered why they did it that way. Personally I think it's because of the A/C box on the firewall, and the wideness of the 4V. The heater core supply for the 2V actually comes out of the top of the pass head, where the 4V HC supply comes out the rear of the pass head. Kinda tougher to plumb that with that A/C box in the way.
Here's how I solved that:


It's not for everyone, and it took a lot of work. but the 4V is wide, and so is that A/C box. Panthers are unique in the modular community for having their HVAC boxes mounted on the firewall. All or most of the chassis that the 4.6 modular motors came in (outside of the Econoline vans and some others) have the HVAC box mounted inside the cabin, which leaves a lot more room in that area...
This will fit a 5.4 DOHC BTW, already took the measurements...lol.

Either way, the MM cooling system is not that different from the familiar one, only that it exits the crossover instead of the rear of the cylinder head.
Returns to the back of the water pump either way.

What is the advantage to modding the cooling system?

I'm teeing the p/s and d/s to the heater core then to the back of the water pump. Made a custom coolant pipe and deleted the original location. Seems to work good so far.

Interesting approach DTUB. Are you using the Evenflow connectors? Or did you make something custom to connect to the back of the cylinder heads? Either way I know it's top notch to go on your MM.

BTW love the sig... Thanks for the shout out...

I'm using the original evenflow parts that fit in the heads and fabed the rest. Driverside elbow is .375 id and ps has a .375 restictor welded in to help even the flow between the too heads.

My kit will replace the discontinued even flow kit, it will not have the adapter that requires you to cut the upper radiator hose. I include the nipple and bung to be welded into the cross over pipe, and I do not use screw clamps I use crimp clamps all included.

Some think it is necessary for cooling #7 & #8 cylinders better but there are a bunch of us with tons of miles that don't have a cooling mod and we are just fine!!

It's a "feel good" modification that may help if you run on the edge with boost and a lot of spark advance!! It won't hurt a thing if done right!!

It is a great and easy modification, it is a proven fact the cyliders 7&8 run 50 degrees hotter, 90% of engine failure will be these pistons, and this is one of the reasons why.
