My 96 deville sits im my parkin lot now a days, its been 2 months since I last ran her, and when ever I try too it heats up real fast just a few blocks away (up to 250 just 3 blocks away from my house) ........ I know that a head gasket job for the northstars are real expensive and im wonderin if its really worth it to doit it, I recently before this problem I had a transmission work on my car because the car woulnt shift, It cost me $850 and thats a fair price from what I hear..........How would I go and start this head gastket job? I have a mechanic that migth wanna do the work for cheaper in my parkin lot. What special tools do I need? I dont have a lot of experiece on mechanic so If u guys can send a link explain the work i would appriteated........Also my car has every thing almost new except the motor (rebuilt transmission, water pump, thermo, radiator, new battery) so im wonderin if fixin it its worth it, and also if the job its done if there is a chance that the same problem migth appear.......Im willin to read info about this and appretiate this site because I learned so much about my car ( a lil late but yea) any info on this problem its truly appretiated.
