evening peeps,i have an alloy thermostat housing with a steel t piece rammed into a hole in said housing,thats the way it came from the factory.
the T piece is a bit rusty and i want to replace it with a readily available brass T piece .
i have JB weld and araldite,what would be best ?.

I would use the araldite but warm the items up it goes on better great for fixing ally sumps

I have used ali chemical weld type products, like arldite, a few times. It is very rigid and brittle at the joins so it may not be the right stuff for anything that vibrates or expands contracts.

I have also used No More Nails metal sealant adhesive. with good effect. This stuff is a lot less solid and almost has a silicon seal feel to it. Stuck two pieces of ali together well enough that I cant get them apart again. This stuff will also be water resistant and obviously better for things that vibrate.

Good luck.

PS I take it a bit of wet dry cloth and elbow grease is not sufficient then?!?

thanks for the replies guys,cant clean it up really as they rust through so better to replace it

I presume it's the main outlet so pretty large hole? If not, are you able to tap it and use a fitting from somewhere like Think?

Is it off an mx5? i just did mine, it had rusted through completely. I bought a brass barbed elbow off ebay and drilled and tapped the housing and then fitted the new elbow. far better than just glueing it in.

STE.your right there,need to get a 1/8 ? bsp tap to do that ,i only have metric,tis a more permanant fixing tho

8mm O/D Steve.
