I have been reading other forums and I am told that the high temp fan doesent come on till it gets to 235.. Crazy im putting it back together and flush it good.. then a new thermostat and new antifreeze and it should be good to go.. Has anyone used the 40 below stuff?/ does it make a difference or something to plug up the system? I am also installing a manual switch for the fans. i dont care what the book says I dont like getting it that hot.
Thanks for the Help
You've probably already started, but just in case you haven't...
As always (well almost always) listen to the great n powerful OZ above (Vetteoz).
You sound new to vettes, and if so you'll soon find out that there will be plenty of blood, sweat and tears without inventing more. In other words, if it ain't broke, don't fix it. Vettes are a pain to work on simply because everything's so tightly packed. Not to mention the many things that are different from most any other car you've worked on before.
That cooling system for instance is a reverse flow system, meaning that the coolant flows in from the top of the radiator and out the bottom of the engine. Which for one means that there can be no air in the system. There's a procedure for getting the air out of the system, which I haven't had to do so be sure and look that up. In your case, I think the only thing I would do is put a thermostat back in (the OEM one). As far as the pump goes, if it weren't working you'd already know. Plus with the C4's LT1, the opti spark seems to go out before the pump and because of the location, the pump gets changed when the opti does, so..... On the other hand, if the pump does go bad first, it leaks onto the opti and vala, the opti gets changed with the pump....
See, blood sweat n tears, plenty to go around....:toilet:
