It's at least a three hour job, as indicated. But also, be sure to completely clean all ducting, and replace blower hoses. If you don't, you'll continue to have residue on your windows, and especially when the heat is on it will stink like urine! Clean it up! Answer I bought an 87 Corvett with the Heater core disconnected. I had an estimate and it was around $350 with new radiator fluid, from my trusted mechanic. The Chevy dealer quoted me around $800.00 with a radiator flush included. The core is around $35.00 online, but I found out that it is about a 3 hour job and not fun to do yourself. The core is located up behind the right front dash. KE
