throttle body coolant block off

throttle body coolant block off
While I.have my motor out I want to clean up the engine bay as best I can. I've seen the bypass kit and read the threads, but can't find anything on blocking off the ports. Is it necessary to bleed coolant past the thermostat with this line? Is the heater core in parallel with the tb coolant lines?

Hey p8ntman
Here's the DIY
https://www.rx8club.com/series-i-do-...***-mod-36389/
And here's the discussion on the value of doing the mod

FWIW IMO I'm glad I did the mod however it didn't do anything performance wise, it's just easier to take the UIM and TB off.
(which I seem to do quite often)
I reported your duplicate post, I've seen the web browser or server do that sometimes. <dunno why, shrug>
Anyways just in case you don't know ... double posting is against forum rulz
Cheers

OP I'm interested in doing the same thing. My solution was to pull the lines and cap the ports with some rubber coolant caps you can buy at any parts store. One of the ports is fairly easy to get to and is down near the OMP. The other, like 9k said is on the rear iron and seems like it would be a pain to get to. I haven't checked into going through the wheel well, though. I want to get rid of the lines completely, if they're not to impractical to cap off.

Physically blocking the coolant points is not a difficult task. I'm asking more about if that coolant bypasses the thermostat and always allows flow? Also does the heater core do the same? I want to know if prohibiting flow through those lines will have unintended consequences.

Yes it is always flowing and no blocking it will not cause any ill effects, many turbo guys (me) use that circuit to to feed the coolant lines on the turbo. I have since put my turbo on it's own coolant circuit with a pump and heat exchanger so I just have a line running from the rear nipple to the front nipple since blocking them using caps did not work since all the caps I could find eventually fell apart and leaked.
The next time I have the engine out I will remove the nipple on the rear iron, drill it, tap it, and install a proper plug and then just remove the nipple on the Tstat housing and have it welded shut.
But why do you want to do this?

I want it gone because it makes pulling replacing the motor that much easier. I would like to simplify as much as possible. Also I remove it on all my other quad4 powered cars.

Team, The motor is already out of the car for a rebuild and I want to block the coolant lines before I re-install it, unless someone says "hey, don't do that because xxxxxxx" and their reason is a good one to maintain flow past the thermostat at all times. I know on other cars the heater core is a parallel path around the throttle body, I'm just new to rotary engines.

What size are the holes? Couldn't you just put bolts with a washer and some kind of sealant to keep from leaking? I want to get rid of the line as well but mainly because this is supposed to be a summer car and I want to clean up the bay as much as safely possible

Actually the easiest thing IMO is to remove the hose from the water pump neck to the TB, take the hose that goes from the TB to to the back of the engine and reroute the TB end to the water pump neck remove/cut off the excess, and connect it to the same nipple the other hose was connected to. Fully bypasses the TB and no extra parts needed ....

I have no interest in bypassing the TB and leaving the hoses, I want only to block them. I did read today that to bleed the coolant system you must remove one of the TB hoses. I will have to find another way.
Its seems like nobody on this forum reads posts completely. A lot of people already know what I should want.
