My 626 over heats constantly. I checked the thermastat and it is goog. It is full of 50/50coolant, is there maybe something clogged up in the system and how would I check for it?

Verify that the fans are coming on, you may have a bad motor or fan relay, best thing to do is, hardwire the fan to the battery to see if it comes on, if it does, I suspect the relay or the engine coolant temp sensor, which tells the ecm that the coolant is hot enough to turn the fan on and bring the temp down
