Wow well thank god for that light even as a tech when you start mixing things that are not suppose to be mixed into one another then you have to clean the whole system flush it it is just a pain wow though thank you for the warning next time if that light comes on I will def. have to check it out Thank You.

 

and i am one of those guys who does not like the dex cool and personally think that it has to do with helping the plastic intake gaskets to crack the first time my oil was turning into orange kool-aide it wasnt pretty thank god i discovered it when i got my car out for spring...it no longer has dex-cool in it

 

That is great, i wonder if gm made the fixed any of the problem with the 97' and made it better so it would not have to go through so many head gaskets?

 

instead of dex cool.. do u just use normal 50/50 mix?

 

no the problem carried over to the 3400's so all you people check the intake gaskets frequently its beacuse of the steep angle of the intake manifold and the way the heating cooling of the engine works against it... it seems to be about a 65,000 mile part almost right on scheduel you will see the side of your engine getting wet...thats what it is....i cant stress enough check your oil up to a light and look for fine orange bubbles(or the color of your coolant)

 

So do u belive it may be better to use a 50/50 mix or can't we do to GM ? must we use dex cool? becuase see the car when i bought it sat for a year and i check the antifreeze and Its Green??

 

pretty much but you have to flush it good first but the intake gaskets will still go its a poor engine design... runs good but that is its flaw

 

Ya it is sad to say maybe ill can get lucky and that will not happen... i have looked around the engine inside in out and have not seen to many leaks ... hey i no this is off the subject but what is a good way to make that intake shine?? sorry to be so off topic ..

 

well they all seem to do it, 3100 and 3400's as for the intake, do you mean the plenum that says 3100 on it. well its like a satin metal so you cant polish it. you would have to actually grind it enough to make it smooth. i pollished up the lines that were on mine and the 3100 with a dremel and the right bit then took metal polish to it

 

thanks ya the pleneum... would it be possible to see the oil and antifreeze mix on the spark plug? probably i would imagine you know? I just hope it doesnt i have already had enough issues to deal with on this one
