1997 Chevrolet Venture lighting problems

1997 chevrolet venture. Headlight lens cover. Last summer I noticed the drivers side lens was loose so I glued it back on with epoxy.(cost $3.00) recently I found out that the passenger side lens had fallen out sometime while driving.(both fell out within 6 months of each other) I went to wash the van and the halogen bulb exploded and flamed when it got wet. Had I been closer to the vehicle I could have been struck by flying glass.

From about 40000 milesproblems with the temp gauge indicating engine running hot when in fact it never was and coolant was adequate mechanic never able to figure out 60000 intake manifold replaced 90000 miles engine losing power and stalling engine block cracked possible and head gasket. Brakes noisy with a grinding feel in the pedal lights on dash on & off ABS and coolant low when no problem exists! Car pulls to left and hard to steer in a puddle horn almost impossible to activate.
