S10 Blazer overheating

[pommie_cj]

 

Back about two years ago, my 1991 S10 Blazer started to overheat within 10 minutes of starting.

 

Someone told me that it was likely a head gasket. Does this sound viable? It made sense to me so I have replaced the head gaskets. I have not yet fired it up to see if this worked and was wondering if I should be concerned about anything else?

Possible clogged radiator. Make sure you replace the thermostat. If it overheats after you start it the first time, don't freak out. Sometimes there will be an air pocket that will not go away until the t stat opens.
