stand alone thermostat housing

IIRC, the engine in the 2002 does.

Circle track guys have a lot of cool parts:

Probably uses a cheap Chevy waterneck.

You'll spend more than $70.00 in your time making one.

the BMW M42/44 does NOT have a standalone thermostat. I think the M20 might.

The fiat 124 does

What size hoses? Most thing Italian have that style.

Buy new there only $17-$19

Land Rover Discovery Series II (2000-2004). Part number PEM100990K. About 20 bucks. Housing and stat all in one.

BMW M10 is readily available in 71, 75, and 80degC versions for under $20 each: Linky

Pardon my ignorance, but how does a remote thermostat help the car? I don't think I understand............

Ford 4.6 DOHC. 96-04 Cobra, 93-98 Mk VIII, etc.

I know the one in the fiat 124 always allows water to flow. When closed, it simply recirculates the water out of the head back to the pump.. I assume this alleviates hotspots in the engine as it warms up?

i think it's more of a packaging thing than anything.. personally, i'd prefer to have the thermostat mounted on the engine so that it reacts more quickly to the engine temp than it would if it was mounted away from the engine.

Right on, that's why Fiat went from t-stat in the head where the water pump just churned water that wouldn't move to an external 3-leg design. They're nice, aluminum housing, and big, and around $50...

It was originally only in marine applications, and featured a very "unique" cooling system. The thermostat was located in the intake manifold (which I am not using)... and wait for it, controlled water flow through the cooling shell of the exhaust manifold...and through the voltage regulator. It was the most bizarre cooling system I've seen in 25 years of messing with cars.

yes.. marine engines are odd that way. But if you think about it.. in a marine engine you are fighting not only overheating, but overcooling. By running the cold water (face it.. most lakes and oceans never get into the 90s) through an exhaust manifold jacket, you warm it up to what would be approximatly the correct temp to boil.. and then run it through the engine to keep the moving parts from getting above that temp..

This has the side effect of cooling the exhaust so you do not get too much heat underdeck

Boat engine? Weird. Yesterday, I just found out that they used the 2.3 Lima engine for boats (OMC Cobra 2.3) and got crazy ideas of a MS'ed turbocharged SVT Zetec in a boat...

yup.. they did. Friend of mine had a small 20 foot boat with the 2.3 hooked up to an OMC outdrive. Was not a fast boat, but very fun and reliable

Is this the 3.7l "half a 460" engine?

If so, MORE DETAILS PLZ.

In reply to iadr:

Ummm....yep. That's a new one for me, too. Does the voltage regulator get hot enough to require water to cool it? I always thought that an outboard would be interesting in the right car. I've seen people trashing boats and motors on CL just b/c of a bad hull.

Good luck w/ the project!!!

Boat volt regs do get hot. Everything on a boat uses many AMP's of power it not unussual to see 200 amp alts

I love the fiat design.. it is simplicity in itself. When closed, the water in the engine continues to flow through the block and head, leading to an even warming, then as it starts to open, it slowly allows cold water from the radiator to mix in.

Somebody fairly clever came up with that system

In reply to mad_machine:

Makes you wonder if the Germans helped those Italians...

Not sure.. but I can tell you this.. when the thermostat in my fiat failed.. A screwdriver and a gallon of water got me back on the road.. I just pulled the stat and flipped it around so that in it's stuck closed postiion, it still flowed water through the radiator.

was a VERY cold 50mile trip home as the engine never got warm enough to produce heat.. but at least it was better than a tow

Whats the bottom silver unit off of? Model / year part number etc.

Any details.

I haven't seen any HAMB thread, that group of people seems like exactly the kind of people I don't like, so I never go there.

If it hasn't already been mentioned, M10-powered BMWs do (2002s, early 318i), etc.
