Thanks ALL!!!
My 46 Chevy has passed the state inspection. With all of your help I was
able to get the breaks/brakes (stopping system) working. After bleeding the
system a few times with a one man unit it was still a no go. Well someone
spoke about a bench bleed and was told not in the 40's. I pulled the master
(try number 3) and howned the crap out of it. Put it all back together.
After I put it back in the truck I pumped it until no air bubbled up from
the master into the reserve tank (this was missing on the first two tries).
I then went to each wheel and bleed the system again - with little air. I
also adjusted the toe board clearance moving it more away from the master.
Well all of these changes worked. I started with good pressure. And the
second day the pedal seemed to engage about 25% higher up. It has remained
at this position for the past few days. I still have the rear brake pads
turned in all the way and they seen to have stopped rubbing. The man who
did the inspection and will do the kingpin work for me told me to drive it
about 100 miles then do the adjustments. The main thing is that it all
works - THANKS AGAIN LIST.
Now the new issue. Cooling system. I have a very old cap that has one side
cut off and it is not fitting tight to the radiator. Should this be
replaced ASAP?
The top radiator hose had a small leak. So I got a replacement hose. In
replacing this the fluid overflowed some on the quick swap. With the new
hose in place the hose no longer leaks. Could this have made the thermostat
stick? I topped off the radiator with fluid and checked - it was good to
-10. Well in driving to the inspection I got a boil over, it was about a 10
mile drive. They refilled with juice and told me to take it home and flush
and back flush the radiator. I got about 1/2 pound of muddy dirt out of the
system.
I then re-filled the radiator, good to about -10. If it sits running on the
driveway (1/2 hour) it will go to about 170. On any drive over 3 miles it
will go over 180 then at faster speeds get into the dot to 212 range. I then
pull over and let the motor run it will cool down to 180 after 15 min.
Next, I was told to replace the thermostat, the one I pulled was rated at
175. Going by the shop manual I put in a 160 thermostat. I now can drive
it and it stays around 180 or a little higher when I drive.
However, last night after a 5 mile drive, I shut off the motor right away
and the radiator boiled over. Should I keep the motor running to cool it
down after each trip? The outside temp is around 60 so I can not guess what
this would be like on a 100 day.
I late last night filled it with just water. Today I drove it about 15
miles and the tempture stayed between 160-180 and got up to 190 on a big up
hill once home it did not boil over. Is it fixed or do I need to take some
action. Anything that I am not aware of?
Also I have a heater system and have turned it off since it is so warm -
could this be related to my problems?
Thanks again.
