I have no idea. It's been a decade at least since I had it done and I don't remember what I paid.

 

i bought a 95 5.7 van , same issue hot in summer ok in winter with no ac. was told it had new wp , hoses , fan clutch , belt, thermostat and radiator , all looked replaced . found problem . had radiator leak , they added bars stop leak , . warmed up , took cap off . as i revved engine , radiator made enough pressure that i had trouble holding rag in opening . so low flow from top to bottom . boiled inside with aluminum brightner , worked better , not good enough for ac . Fixed with a good flushing and new radiator .
