Read your original post as the temp sensor being in a pocket of air. Carry on

Water is highly conductive, thermally. If the temperature of the coolant flowing out of the thermostat changes by X amount, I'm fairly certain that the CLT sensor isn't going to be blind to that just because it's a few cm outside of the primary stream of coolant.

That part of the design doesn't bother me at all.

Shipping to outside of the known world
 

Wowsers - Fedex to Australia is an additional third of the base cost.

There are clear upsides to living here - no guns, no Trump. But the postage...

I cant seem to find any pics of this kit installed, i really just want to see how that radiator hose sits in the engine bay. I cant tell if its a straight piece of hose or molded to fit.

Not molded. You generally end up with a simple curve around the side of the engine up to the radiator.

You could move to Texas where the shipping is less, but you may choke on the sweet air of freedom and liberty.

I have someone who can ship me things from Australia, but we dont, because it is so damn expensive. What gives? It costs less to ship things to Asia.

They have to carefully inspect all packages for guns.

We paid our Australia Post CEO AUD$5.6mill (USD$4.4mil), that brings up the cost of stamps.
Australia Post CEO salary revealed: This is what Ahmed Fahour earns

Might have something to do with the fact that 4.4 billion people live in Asia and 24 million people live in Australia

How much of this is actual shipping cost, and how much is Tarrifs, duties, etc.?

Shipping to Australia vis USPS should be around $85~90 with insurance. The boxes are about 8" square, maybe 4 lbs.

I like the bleed screw, nice touch. Nice looking machining too.

The spring inside radiator hose rusts, but the inside of your iron block doesn't?

Grounded vs not grounded (sacrificial). Possible that figuring out a way to ground the slinky would save it. Dunno. In any case, it's a internet conjecture thing. No one that took a few seconds to make sure their hose was routed properly and cut to the right length has ever had an issue. It's not rocket science.
Just make sure it has room to grow an inch or two and isn't chafing on something sharp. Done.

Yeah, I've never used those things inside my hoses, i didn't even know they were popular. I wouldn't think they would rust either. The more you know...thanks.

Emilio, any recommendations for hose routing?

I've personally only done one reroute myself. Rather than one long, I used a molded rubber 90 at the back, then a rigid aluminum tube, and then another molded S-shaped piece at the front (can't recall which car it was from.) This seemed nice and safe to me, as it was easy to anchor the tube in place to where neither it not the rubber sections could chafe on anything.

Nothing tricky about it. Just a big arc from rear to front. Flop the hose around to make sure it doesn't grind on anything or get pinched. It will naturally lay on the frame rail or thereabouts. We sometimes add a loose clamp off the intake manifold. Clamp has to be plastic or rubber lined and larger than hot hose so it can move around a little.

Editing a video now that shows a typical installation.

Freeze plug not necessary with the blockoff plate in head in front?

We haven't found the need. Note how thick our block off plate is. It ain't leaking. No harm in having a freeze plug and plate though.

Cool. :) Me gusta.
