Later Cooling shroud on SWB

[hdavis]

I've read a number of times here that fitting a newers style cooling shroud to my SWB engine will do wonders for cooling the engine more efficiently.

Is this what I need? Will it be a direct fit on my '68S?

I'm not sure about the exact holes for wiring, etc, but that shroud should work. If your shroud is for MFI, you probably need an MFI shroud to clean the injectors (as opposed to a 70T shroud, for example). I think 68S's were MFI? Other than some small details it should fit no problem, but I am not near the expert some of the others on this forum are. Hopefully they'll chime in.

68S cars were webers 40 IDS carbs, not MFI. The seller of the shroud says it's for a 73. NO ! It does not have the cutouts for the injectors. It looks like a 3.0 CIS shroud from 78-83. It will work on a 68S carb car, but it won't be original. It will have the duct to blow air on the cooler. But a 2.0S doesn't need it........

Hello: If your 2.0 is running hot then something is wrong. You may want to check the oil cooler to see if it has a nest on the top of it or leaves or old oil. The 2.0 engines just seem to run cool. Also check your ignition timing as well. If you take your engine shroud off and check the top of the cooler I will bet you have stuff on it. I would keep your shroud on the engine. Thanks Eric

Henry-
If you need a new shroud, check with the guy that posts on Pelican under the name Series900 (his name is Damon). He makes beautiful shrouds in a variety of finishes for not much more than the opening bid for the item you referenced. I have one on my wish list!

I believe that a 2.0S can indeed run too hot, even when in perfect tune. Depending on altitude, humidity, timing, and usage, the engine mounted oil cooler may very well be taxed. Recall that 2.4S cars had a front mount, radiator type cooler, *in addition* to the ducted fan shroud. So these engines can get hot, especially when driven spiritedly, otherwise the factory wouldn't have deemed a front mount neccessary. Considering engine longevity correlates directly with operating temperature (when in excess), cool temps should be a priority, and with a thermostat it really shouldn't be a problem of pushing too much air over the oil cooler.

I don't want to speak for Damon @ Series900, but it was $250 for a 2.0 exact replica shroud in June, and he makes shrouds for the later early cars with ducted oil cooler. He also makes them in amber, which I think is a great R Gruppe / 906 look. Damon is a stand up guy to work with, another plus. Getty Design also makes shrouds.

You can also lower your temps buy running a high ratio fan (1.82:1 being best), with larger crankshaft pulley and small fan pulley, and even a larger fan, like that from a later turbo. Pelican has some great threads on this, and Grady Clay even reported an increase of HP from the cooler heads.

2.0L S's will run hot when pushed and even more so in a hot climate like Mexcio, A search will reveal a lot of 67-68 S owner's who have battled high oil temps and a later shroud seems to be the most cooling change for the least amount of money. I am in the same boat and am thinking of the later shroud also, so please keep us posted, with results.

I just installed a 2.2S engine my 1966 car, and that engine runs significantly cooler than the stock 2.0 unit. I even used the same sending unit and fan assembly for both engines. The shrouds are quite different.

Klaucke-
Pictures like that will bankrupt me!

Thanks for all the replies, my 68S is carburated as Rick mentioned, but it does run hot. I've checked ignition timing and it's OK, but I haven't checked the oil cooler or removed the shroud to see if everything is clean. But I already have a smaller pulley which worked a little. I thnk I`ll check the top of the cooler first and give it a good clean. I do need to remove the carbs for this don't I?

Having said that, it might be appropriate to mention that my car runs too warm when going at 90+ mph over some time (20-30 minutes), in warm weather and at over 7,000 feet. If I slow down to 60 mph, it cools down to reasonable levels.

Klaucke, that's one good looking engine....
