[V8] Overheating - revisited

[Jeff Goldberg]

 Clogged radiator. 

Recently changed mine and all is well.

Cheap replacement at autocoolradiators.com  There have been lots of
recent comments on this radiator.  If the car is your "baby" and you
want to keep it stock I would look for the OEM radiator.


Old post:

I too spent quite a bit of time modifying the upper and lower rails
of the radiator.  Had to cut out a section to allow for hood latch.
Grind the entire bottom thinner to drop radiator down enough to get
the trans cooler lines to line up.

The old radiator core was 62mm thick, the new one
(autocoolradiator)was 40mm.  To me that is a huge difference. 

It does however work.  I let the car idle for 30 minutes with A/C
on, outside temp 86F and never went over 100C.  It runs cooler while
driving as well. (<100C)

Howdy, gang!
230K on the clock, and running as strong as ever.  My only problem
is that once the outside temp is above 80-85 degrees, I DO NOT DARE
stop in a drive-through, and PRAY not to hit a traffic jam!  The
reason being that my 1990 V8Q will run all day long and as hard as I
ask it, maintaining a sub mid-point temp the whole time.  10 minutes
stopped, however, has my temp gauge skyrocketing.  Shutting down the
A/C and revving up the engine in neutral helps to being the temp
down a bit, but if it lasts more than a few minutes, I am dead in
the water with what seems to be a vapor lock.  No amount of cranking
will bring it back to life, until an adequate amount of cooling time
has elapsed.  Am I fighting a failing T-stat here?  All fans operate
as they should (checked all of that out).  This is my third summer I
am facing with these issues.  I am seriously considering parking
this V8 for the summer and only using it for a cold weather car (85%
of days here in Wisconsin anyway).  Any ideas??
