ok, i have an 88 n/a and the watter seals are blown....so the other day i tryed flushing the system to do this temp. block sealer stuff that i was recomened till i swap it and it wouldnt flush so i was told the thermostat was stuck, is it worth it to go buy a new one and do the block sealer?

 

no, the block sealer stuff it will do next to nothing to help solve the problem and then when you go to rebuild the engine you'l have it everywhere in your coolant passages and cleaning it out will suck.

 

like i said...TEMP. its gonna be swaped in a couple of months

 

its gonna be in the rad too.. so hope you replace that. but if your gonna put it in and do it cheap way.. just remove the thermostat
