95 Integra Radiator
 

I just took my car to a mechanic because of a radiator fluid leak.
Apparently, my radiator is old and needs to be replaced. I was quoted
about $427 for labor and parts. And also, he was recommending that the
coolant system be flushed and change the parts related to it. And
that's an extra $600, totaling about $1100. Does the price sound
reasonable? I've been fooled by many mechanics before and I don't feel
like I can trust anyone with my car nowadays. HELP!

Thanks in advance!
