Questions on my 79

[page62]

Hot. Keep working on it.

Have you done a power flush and fill yet?

I don't want to be a broken record, but this is exactly what my '75 did before the new radiator. I could run fairly cool at 55 mph. If I pushed it up to 65-70 the temp would just continue to creep upwards. I make fairly frequent trips from my home in Whittier to Seal Beach where my son lives. About a half hour on the freeway where, on the weekends, you can maintain 65-70. Before, it would creep up . . . but now with the new stock radiator, it runs at thermostat temperature which at the moment is 180 degrees. I can push it all the way up to 85 or so and never see a temperature rise above set point.

Prestone and their competitors, with all of their fancy flushes and cleaners, made a fortune off of me before I finally broke open my wallet and bought a radiator . . .

Now, I'm , ,

Oh, by the way . . . the engine is now far from stock . . . still runs cool . . .

Page, Yes I disconnected many hoses and flushed out everything untill it was clear water. Also I flushed the heater core.
I think the radiator does need to be replaced. How ever, as you can see from my tests, my only probelem is during highway speeds. When I take it to work, It stays 195 constantly. Highway driving really isnt what I use the vette for. Also I can say with a certain degree of certanty, the gauge is off by at leist 10 degrees.
Ron... you are right.
However. the radiator will be put to 3rd or 4th on the to do list (unless it blows) I need new foam and seats, And the air needs work.
It looks like the radiator slides out. Any thing else to worry about?
A funny side note. I tested the C.B. delco stereo today and it actually works! I see that was a very expensive option 450.00 back in 79.
thanks for the help

Rule of thumb: mechanicals first, esthetics second! The seats can wait, the overheating can't! You'll fry your engine if your leave it...
