Default Peter Pan Coolant Reroute

Parts you need

You need to go to hydraulic supplies store and purchase the following
1/2 straight brass fitting - around $4.00
*3/4 brass stopper (If you have a turbo I am using a 3/4 to 6an 90 degree elbow) - around $5.00
1.8 Miata thermostat outlet coolant housing
Protege water pump inlet coolant housing (If you want to keep Power steering and A/C look for Mercury Capri) - $10.00 junkyard
Discount Autoparts coolant hose part # 300077 - around $6.00
2 Throtle body AIC clamps
JB Welb $3.00
sand paper $2.00
silver paint $3.00

Grand total $33.00
Look at the pics / I am ready to debate.

I'm totally not an expert, but that doesn't seem like it would solve the major issue as you still have coolant entering and exiting the front of the head.

It seems, thought it's hard to tell from the pic, that you've probably only solved the issue of the heater core coolant going back into the head without ever hitting the radiator. But that's a minor nuisance compared to the bigger issue.

Sometimes, it takes time to digest information, assimilate and understand it well. I suggest you keep looking at the reroute pics / do your research before you comment.

lots of pics of the same two braided lines and no explanation

Pure speculation, but it looks like you're taking the heater core feed from the front of the head and taking the heater core return and putting back in at the water pump outlet. That's not that different than OE.

The two most common approaches to reroutes either address A) evening out coolant flow through the head and block to get even cylinder cooling or B) avoid putting the heater core coolant back into the engine to reduce temps.

edit: I thought this looked familiar

another edit: are those turbo coolant feed and return lines?

Why don't you facilitate our "research" by providing more details so we are more prepared to have a meaningful "debate".

I predict that this will be useful to you Hyper as this thread progresses


although I have a feeling in my gut that things will resemble this soon:


Since I have nothing useful to say here, ill refrain form posting any further

I can't write with this stupid mouse!

I need a complete unmolested diagram of the cooling system. As to how the water pump flows water through the motor.

I see your point. Your rerouting the flow from the heater core to the front. If the flow goes through the motor and out both ends your good.

But I see three different ways water can flow on this. This hole miata setup looks like they got drunk an slept with old asian men.

So basically I need a flow diagram of the coolant through the motor.


If someone has one. Please post it.


That will be the basis of the discusion.

And don't start that I can't spell bs. We ALL KNOW THAT!

Yeah, this way only the coolest coolant enters the turbo which auto preheats the coolant anyways. By bypassing the coolant the way I did it, the turbo gets the coolest coolant, at the same time the fresh coolant that comes from the lowe radiator hose doesn't mixed with hot coolant from back of the engine anymore.

Coincidently, the same theory was explained in solomiata.com.

Just FYI, factory Thermostat in the front, in the back of the engine, the coolant lines were left intact as it comes from factory.

It would be helpful to have a diagram of the system. Instead of marking up the pictures, draw an illustration of the flow. Something along these lines: http://solomiata.com/images/RobEbersol-coolantpath2.jpg (no, I can't draw that well either, but you get the idea.)

Lacking any detail, it appears to me that you have left the back of the head alone, such that water flows out of it and into the heater core. I note only two obvious changes:

1: The return from the heater core appears to go into the thermostat housing, on the engine-side of the thermostat. As a result, the mixing manifold on the inlet to the water pump has been replaced with one that has only a single large inlet, for the lower radiator hose.

2: The coolant feed to / from the turbo is placed between the thermostat housing (pre-thermostat) and the fitting down by the water pump inlet. This location originally had a rubber hose between these two points.

Is that both an accurate and complete summary of the changes?

yeah, you and Toddcod assimilate pics / diagrahm very well. I am using a Protege waterpump pipe housing

someone please post a diagram of the miata cooling system. I think I senior member, "Toddcod" needs to understand.

This re-route doesn't really do much and isn't much of a re-route.

While it is very simple, because you really are only dealing with "replacing" the heater core lines, the same amount of effort or money could be spent re-routing all of the coolant, and pulling all the hot water from the back of the head, instead of the front, which is where it is put in to begin with.

...... just another forum based comment. Start reading the internet write-up I just posted below. I'll respond to your bias comments later.

This is how I'm going to do it...Just the source for the heater core will be just in front of the thermostat at the rear of the block.

Just an observation:

Hyper appears to have routed the heater return pre-thermostat. This is an area of equal (perhaps slightly greater) pressure than the heater outlet at the back of the head. Which means little to no (possibly even reversed) flow through that circuit.

What say the rest of you?

??? I left the cooling system stock in the back. The thermostat is still in the front.
