Kw t660 cooling capacity

[Magard]

I been doing some research on different trucks. I’m looking at different options on a project truck
I’m eyeballing is t660. I know there narrows but the seats have nothing behind them. I like that recliner option with out cabinets in your way. Seems like a dumb thing but way easier on my back. So my concerns are what about radiator. Can it support 650 hp in hot weather. What’s the general consensus on this truck model. Looking at 2250isx 13spd 3.55 actually a small cpl I want light rears and tranny. No water cooler transmission. 76 inch aero cab. Im looking for something to pay cash for then put it in the shop and start at the front and work my way back rebuilding it. Volvo will be tired in about 3 more years. So plan is to have a rebuilt paid for truck to step into. Just doing the research as to which truck to build. I like Volvo but dealer is aggravating to get parts through. I’m not ruling volvo out but the openness behind the seat in the 660 is pretty unique. Looks like you still have cabinets, refrigerator, double bunk, and all.
