Yes, you can do the job yourself... it ijust take time to do it...if you got
the 2.3, it is not too bad of a job... take the fan off... then the radiator
shroud so the fan will come out together... and you got a pretty good access

The 2.6 take a bit more time and effort... you start with radiator out,then
the rest because the space to get to the fan bolts are harder...
In any case, it would be best to have a service manual to guide you thtough
