my 2000 Volvo XC has the occasional loss of radiator fluid, and when breaking and speeding up hard smells funky (my wife calls it farting). Also there is a Small puddle of non water fluid behind the driver seat, this has been going on for 1 year plus and no one is able to figure this out ---

This I figure happens when the heat is on, It may be the heater core or a leak if you have rear passenger heating. What is the smell like? Would anifreeze look like the fluid you see? ---

Does this vehicle have rear A/C? There may be a line leak. You mentioned the puddle was ‘non water’ fluid. Any particular odor to the fluid or distinctive color? ---

car does have rear A/C and heat, fluid is clear and sticky, does NOT smell like antifreeze thought (according to me and my mechanic). Heater core/AC unit was changed ---

I don’t know Volvos, but the heat for the rear has to get there somehow. If it all through air ventilation there is no problem but if there is a secondary heater core for rear seat comfort That system could be suspect. ---

the puddle seam to be concentrated only under the driver seat, could it have something to do with the heated seat there? is this something I need fixing? how much would that run me ---

A pressure test could indicate a loss of coolant, the heated seat would not be part of the problem as it is like an electrical blanket, no fluid. A new heater core you would need to get an estimate, and proper conclusion that is the problem. I would think no more than $500 would fix it, but make sure that is the problem. ---

…especially while “breaking”.
