If you had asked this yesterday I could have measured it for you, **** all if I'm going to take it apart again if I don't have to. Working back there really sucks.

I have an extra pipe that runs from the heater outlet to the mixing manifold I can measure the OD, would that be helpful?

Oh darn. The return will probably also work, but it's the ID of the hose (OD of the nipple) that I need.

Maybe this will help someone: The only snag I hit during the install was a little interference between the top of the transmission and the bottom of the reroute housing.



In the red circle in the image above, you can see a seam where the 2 halves of the mold for the bellhousing come together. On my 5 speed, this was interfering with the bottom of the reroute housing making it impossible to line up the bolt holes. I started by trying to file down the housing, but it was far faster to file on the transmission. Easy peasy. I'll be sure to whack this on my 6 speed before it goes in.

I believe this interference is present with with the BEGI reroute spacer as well, possibly causing the issue Hustler was referring to in his thread of fie and woe.

So you need the ID of the stock heater hose? I can get you that tonight, provided I remember to measure it.

Resurrecting this thread to add some more info.

13958 is definitely not the right size for the Meziere housing. It's a 52mm thermostat, and the kit is supplied with a 54mm one. The 13958 when placed in the housing will cover the hole, but it's got enough slop side-to-side that it can open up a gap if it doesn't stay in that location.

13958 on left, supplied thermostat on right:



(Yes, there's an empty hole with no jiggle pin in the supplied thermostat. I'm pretty sure it had one when I put it in, but it's clearly not there any more. This may explain why it behaved more like a 160F thermostat than the 180F it claims to be.)

Meziere says it's a "traditional Chevrolet thermostat", which appears to be a Stant 13358/13359. At least, that's what you get looking up a 1967 Camaro with a 350, and it measures out as the right size. The Stant SuperStat (better flow) in that size is a 45358/45359.

I couldn't find the part # for the seal that goes on this thermostat. It's not the 25270 mentioned in RavynX's thread because that's for the 13958, which is 2mm smaller. Digging around at the local parts store, the best they could find was this:



Which appears to be intended for various Toyotas. It's thicker than the M-tuned one, and has a slightly smaller diameter (but still larger than the 13958 with seal).



It fits nicely in the housing:


Incidentally, I had also ordered a new Meziere housing as well, in case they'd changed in the 5 years since I bought my M-tuned kit. They have a slightly different external appearance (different radius on the corners), but internally they're the same size.

codrus: great update, +1 for more parts confirmation.

I just did some googling and found the Meziere supplied CARQUEST 30730 PN interchanges with:



So that confirms your Fel-Pro 35278

As for the thermostat, it turns out that the one I actually ordered was the Meziere one via Summit: http://www.summitracing.com/parts/MEZ-WN0070195 probably because I was lazy and didn't want to make 6 trips to get this all done.

Of course I didn't pay attention to the size so I can't confirm but it fit with the Meziere gasket when I dropped it in so I installed it. Seems to be working great if that's worth anything. Pics confirm you are 100% correct with the 54mm thermostat.

FWIW, the Meziere-supplied gasket that came with the new housing I ordered (still need to send that back, since it's identical to the one that came with the kit) is for a 52mm thermostat -- it fits the 13958 that I had sitting around perfectly, and does not fit the 54mm thermostat that actually fits the housing. I have no idea why Meziere would include a gasket that doesn't fit the part. I also don't know if the one that came with that housing was a CARQUEST 30730 or not, I'd guess not because it doesn't match the FelPro. It was also very different from the gasket that came with the 54mm thermostat that the M-tuned kit was originally supplied with.

I think I remember something about a compatable radiator hose from a cadillac that could be used to make the installation a bit more clean.

Here it is:

Autozone XL-1215

As mentioned in: https://www.miataturbo.net/useful-sa...-needed-46698/

I used an upper rad hose for a 5.3L 2006 silverado for my M-tuned reroute...just cut it appropriately. It was $20 bucks and was already bent nicely.

Can anyone find a silicon version of the above radiator hose? (for the sake of longevity?)

I've looked and found nothing, but Gates or GM may have silicone blue or green stripe hoses available for "special service" (Law Enforcement/Military) versions of their vehicles. Ford had a set of PN's for what were effectively Gates Blue silicone hoses available for the foxbody Mustang (CHP) and Crown Victoria (Police Interceptor) that were not available anywhere but directly from Ford. If memory serves, I believe they didn't cross reference through either the Ford or Gates catalog. You literally had to talk to the guys at the parts counter and tell them you had a 1993 Ford Mustang SSP. GM may have something similar for this hose but I don't know any GM parts guys.

Does anyone know the thread pitch of the heater hose adapter on the M-Tuned reroute? I lost that piece moving house and didn't notice until it was too late!

I am sitting on one of those M tooned thermo housings. Don't think I'll ever use it. Glad to see someone is using the kit properly.

Clamping range is 1.000" to 1.625" so they should be fine on the 1.5" OD hose.

I don't mean to get all squirmy over hose clamps, but these things are seriously beefy and high quality. I'm going to go measure the OD on the rest of my coolant hoses and buy new clamps.
I know it's a bit anorak to get worked up about hose clamps, but I've been happy with Murray Corp Constant Tension Turbo Seal Clamps TSS (p/n TSS16S30EP) used in conjunction with my M-tuned coolant reroute.

Pile of hose clamps

Hose clamps installed

Murray flexible hose clamp driver is a bargain at $10.99 especially for hard to reach hose clamps

Nice clamps!

I have no problem nerding out about hardware, I'm just tired of seeing people use Home Despot "stainless" "steel" clamps on silicone. Gahhh.

If you don't mind me asking, what was the pricing on the clamps? I'm seeing like $65 for a 10 pack?

Also, for those who didn't already know, most molded radiator hoses don't have a constant diameter. The dimensional accuracy is best and the geometric tolerance is tightest on the ends, as that is where it is most important for achieving a good seal. Thus, if like me, you're chopping up pre-formed radiator hoses when custom plumbing your cooling system, you might find that your fresh cut ends aren't as tight as you need them to be. These Murray Corp hose clamps are super strong and you can really crank them down if need be. Not all hose clamps can do this. I've certainly cammed out my fair share of hose clamps over the years by asking too much of them. I know over-tightening hose clamps is not ideal as you can easily over-stress aluminum piping and connections, but in my case it allowed me to achieve a leak proof seal. Ultimately, after a few heat cycles, the custom cut silicone radiator hose conforms much better to the pipe anyhow and you don't need to crank down on the clamp quite so hard.

Yes, that's what I paid. Expensive for sure. But then again I had a special need for them. Not everybody needs to go so extreme. Plus I like buying American from a local business to boot.

I know AMS tried these Murray clamps to secure silicone couplings for intake charge pipes on built R35 GTRs and had mixed success. YMMV.

Necro thread! Interestingly I was just looking at this particular thread recently. I'm going to try these ebay cheapies for my coolant reroute which should go on this weekend. will report on their function in my build thread.

Hey I'm pretty sure the original pieces of this reroute came off my old Miata. FWIW I never got that damn tstat housing to seal
