Hello All. Going to look tomorrow at a 99 k1500. It's a very clean LT, current sticker and everything works, about 1/3 of the going rate in my area. However it "needs a heater core and has an overheating issue." The seller is pretty bad and doesn't seem to be mechanically inclined. I did gather that they took it to a shop, weren't willing to spring for the repair, and decided to sell.

Looks like the core is a simple replacement and I'm fine going through a cooling system. But anything I should be on the lookout for? Are Vortecs known to blow gaskets, etc? This will be my first Suburban and first Vortec.

Thanks in advance!

 

My 98 K-1500 has never had an issue with the heater, nor much else. Thing is I take care of my vehicles. Yeah I put a water pump in in four years ago, but the thermostat
is still going strong, along with the radiator and most every thing else for that matter. No sense in buying a vehicle that has probably not been maintained, to me anyhow.

My Vortec head gaskets have not leaked, and I dont think its an issue, at least on the older Chevrolet's. Quality control in all manufacturing has really taken a dive the last
15 years or so, IMO.
