MG MGA - Fan Shroud

The rubber hoses started to deteriorate and they were leaving little black chunks on the rad cap. While changing the hoses I decided to add that fan shroud I bought way back off ebay.

It was kind of a PIA to install, and the fan rubbed it on the top (fixed with a sharp utility knife).

I have noticed since chaging to an aftermarket radiator, the temp has risen from an average 190 to 212 or so. Not a problem until I get stuck on some of the most crowded roads in the world. The kind of jam that takes an hour to go just a couple of kilometers.
As I creap along, the temp would raise to 220 and just keep going up until I could get to some open road or a service area. Fortunately, no boil overs yet.

With the shroud, it goes to around 212 and stays put in stop and go traffic. A steady 190 on the road, even up hill.

Now, if I could just cool that cockpit down.....

Maybe you could take your pants off and wear one of those Sumo wrestler outfits. If you do give it a try, please post pictures.

I'm trying to cool down the cockpit as well. Having just had a loft conversion done on our house, I've discovered an insulation material used in roof spaces called Tri-Iso Super 9 - not much thicker than a carpet, but apparently as good an insulator as something ten times thicker. Costs about £10 per square metre.

I'm going to lay it under the carpet on the transmission tunnel, and at the front of the footwells, to see if it cools things down. My only concern is that it might retain too much heat in and around the gearbox, and raise temperatures too high there. Any thoughts welcome.

I emplaced insulation (1/2 in. felt layer aluminum foil) on the bottom of floor boards and on top of transmission tunnel and foot wells. Works nicely. Regards, Gary

Have you considered going back to the root cause and changing the poor after-market radiator? Those high temps cannot be doing your engine any good, and you have an unnecessary 20-30 degrees of heat trying to find a way out of the engine compartment, most probably via the cockpit.

Plenty in the archives on original spec radiators. Mine runs at just over 170 most of the time and creeps up to 190 in heavy traffic on hot (for UK) days. I dont think I have seen it go over 200.

Met a guy this week end, Jeff Herr from San Diego, who just started racing a pretty stock MGB. He got an aluminium radiator from TAPP Inc. in No. Carolina (http://www.tappinc.net)for $500 or $600 that he spoke highy of. Looked good.
