Hey, i have a 91 pickup with a 3.0 and around 214,000 miles on the motor. I
have been having problems with over heating but i have recently replaced the radiator, thermostat, fan clutch and multiple small bypass hoses and it still overheats. I have come to the conclusion that it is a blown head gasket because i have had it checked and multiple places have told me it is either a crack in the block or a head gasket. I have found on craigslist a 95 runner with the same re-built motor with very few miles on it and i am set on buying it. I dont know what it would take to do a swap like this and i am hoping there is someone out there who has removed/ put in this 3.0 who could offer any tips and suggestions. Anything helps!

 

a set of wrenches and sockets, engine hoist and a little educating yourself.
