hey all

I recently got extractors put onto my 1981 datsun 1200 ute. The shop noticed i had 3 leeking welch plugs and decided 2 replace them 4 me(that was all good), the only problem was they forgot 2 refil the coolant!!!!. My temperature gauge is a bit dodgy and didnt indicate how hot the engine actually was. So u guessed it i warped the head. Ever since that i have had heaps and heaps of trouble with the engine temperature!!!!! I have tried everything. New thermostat, shaved the head down, just got the radiator completly redone and cleaned and flushed. What else can i do or do i need 2 get a new engine?????. Im wasting my money trying everything to fix it, when i had many many plans and mods 4 my engine
plus anybody that lives in ACT or queanbeyan, heres a tip avoid Langs auto in queanbeyan!!. They forgot 2 add the coolant which has caused me all this trouble!!!!
