Could there be more than one style thermostat & housing? I seem to recall it being a separate item in our '84 Spider. (but my recall is not what it used to be...)

There is one listed at Advance Auto Parts "for engines with separate thermostat and housing. But International Auto Parts lists "thermostat with housing".

So perhaps the answer is a definate maybe...

Somewhere around here there's a how-to on modifying the housing so that the T-stat alone can be replaced with an off the shelf item as opposed to buying the housing and all.

That aside, I dunno if my 85 is a unit or not as I've not had it off yet, however an S2 manifold I've got here definitely has the housing and T-stat seperate/unaffixed so that either part could be replaced independantly of the other.

I haven't torn mine out yet, but it's not on the block or water pump where I expected it to be....it's in it's own little housing off the bypass hose....I would assume that I could just crack it open and change it out with the one from Advanced...

Should be 180deg or something lower?

Of course, when I search Advanced's site, it tells me that there are no parts found for my vehicle...:eek:(

Thanks for the help

In decades of working on cars, I've never seen on on the block or water pump at all :shrug:

They've always been on the intake manifold on stuff I've worked on. (current Alfa inclusive)


Anywho, I'm holding the T-stat out of the S2 in my paddies right this second.

Data stamped on it, for whatever good it will do:

BREVETTATO SAVARA 10046/90/B


Now at a reach, I'm wildly guessing that /90/ is the temp range in celcius, and a quick trip to the convert stuff to other stuff shows 90C = 194F (however that doesn't neccisarily make my guess correct in regard to the P#)

From memory, I believe the factory NOS thermostat is 180 degrees. Some guys run 165 degree thermostats, to circulate the coolant earlier.

I'm running a 165 degree thermostat now, and it seems to run a few degrees cooler with winter running (Jax, FL -- so not really winter). The 180 degree thermostat running last summer had termperatures reach 190 degrees on my temp gauge.

My 1975 motor (1300cc) has the thermostat in a housing which is integrated into the intake manifold. To replace the thermostat, you simply unbolt two nuts, and pull the top of the thermostat housing off, clean of the old and replace the new gasket, and top off the fluids. (You need to siphon off some of the coolant, so you don't spill a bunch, when you take off the top of the thermostat housing.)

Find the right part. You won't regret it. Though a few dollars more, you don't mess with Alfa's cooling systems. There are enough headaches as is, keeping the head and block tightly mated with the head gasket between, to stress things with overheating.

I'll find out

I sourced the 165 degree thermostat from my mechanic. I'm dropping parts off to him tomorrow, and will do my best to remember to enquire where he sources this part. I have a 180 degree thermostat from Centerline or IAP in the parts cabinet in the garage.

I'm using the 165 degree unit because my mechanic advises to, and he's been the local Alfa guru for the last 30 years.

Talked to my Alfa guy yesterday and he told me that the thermostat was a "standard Ford" thermostat.....I am not sure which standard one it is tho...but I bet if you asked the parts counter for a Ford Escort 165deg thermostat, you will probably have the right one....

(let me know if anyone tries this before I do...:)...)

When he says standard ford he probobly means the small block and big block V8, I6, and older 4 cylinder thermostat. I can not remember any part numbers any more, but just look up a 70s anything w/ V8 (pickup truck, mustang, sedan).
