Ok, I have a 1999 K1500 Suburban 5.7 base model.
This truck is stock and I have all service records since it was a government truck and believe it has always had DEX Cool. The cooling system is Swiss Cheese. Started with heater hoses at heater core leaking (replaced). Then water pump (replaced) now after pressure testing Intake Gasket leaks at rear of engine.
I did not bleed the system properly on the first heater hose repair (now have a Spill-free funnel). So I might of entered air into the system and might of caused all this for my stupidity here
Now I am going to replace the intake gasket and the quick connect thing to be safe.
Should I put Dex Cool back in (been using Prestone Dex Cool) or flush and put Prestone Extended Life? I read that Dex Cool issues have been fixed, but might not be compatible with 90s vehicles but works well with newer models.
Also, intake manifold job looks doable for me just concerned about getting the distributor back in correctly.
Thanks!
