Coolant surge tanks, anyone know?

My Scania engines have a plastic surge tank as a coolant reservoir, but the darn things don't last, they break and disintegrate, the plastic breaks down. My freightliner FLD120 has a metal surge tank over the rad and I'm thinking about buying some and adapting them to the scania setup. Before I do, I was wondering what else might be available.

The freightliner tank is as long as the rad, about 3-4" thick and 8-10" wide (going by memory). Was wondering if any other manufacturers tanks KW, Western Star, Etc. would be available in metal and 1/2 as long as a typical Rad and maybe 8-10" deep and 8-10" wide. If it held about 10-15L that would be good.

PS, the surge tank is pressurized, I think about 9lbs (my memory again ).

Thanks for the reply.

I think mine break because I'm mostly off road, vibration is high and temp low -20C to -40C.

What's the rough size of the tank on yours (guess is good enough). I'll try and search it and see how the plastic casting compares to the Scania.

 

What's the rough size of your Mack tank?

 

Yep, if it comes to that I'll try and use the mig and make one out of aluminum. But I thought I'd try a ready made metal one first if I can find one.
