While I've no idea what the specs are for this particular, large
electrolytic capacitors are used in automotive designs. The example in this
reference: http://images.powerelectronics.com/files/285/ElectrolyticCap.pdf
discusses estimating the life of an electrolytic capacitor operating at 85
degrees C. Caps can operate at these temperature levels, just depends on
the specific one.
