First of all allow me to introduce myself, my name is Erik im 20 years old and im in love with Cadillacs.A few months ago i bought a 1997 deville with a blown head gasket for $700. A tech i know who has never had a comeback from timeserting engines ( has time-serted numerous northstars for his own family) helped me out. Anyways today i finally finished everything, since we had the engine out i replaced almost all the seals. So after im done with everything i start it up but i notice the temperature rises pretty fast. Im very concerned about it so my question to you guys is basically what happens as far as coolant temperature and all that other good stuff, there is no SES light. Thanks for the help.
