Im in the process of selling my 93 v6 with 109k miles and it keeps overheating I replaced the thermostat and made sure it was right side up, it has plenty of fluid in it I feel like I'm I replaced the head gaskets, oil pan gasket, oil filter adapter gasket, and other various gaskets. The car needs a tune up desperately I just don't have the funds for it since I now have a baby on the way and I'm sinking all funds into our Jeep Grand Cherokee so we'll have a family vehicle. someone help so i can sell my maro. Don't worry guys I'll be buying another maro as soon as things stablize.

 

Here is a quick way to check and see if all is well.
Disconnect the ancillary water lines (heater lines) look into the metal portion of the lines for any obstruction. My 94 had some sever plaque build up in the hard lines. Clearing them out and replacing the thermostat and water temp sensor seemed to work well, until I had to change all of the upper and lower intake gaskets.

 

Did you flush the system? Try Super Flush? Might want to install a flush kit (cheap at Wal Mart) Check the hoses for problems/blockage? Is your water pump weeping?

 

the water pump isn't weeping thats the first thing i checked ill check the lines today the thermostat is only 6 months old and i flushed the system the best i could
