<DIV>The main purpose of putting a higher pressure cap is to stop the
continues loss of coolant after shutting the engine down and the engine temp
going up over the 212 point. By putting a 10 or 13 max pressure cap you
have raised the boiling point 10 to 20 degrees thus stopping the coolant
loss.</DIV>
<DIV> </DIV>
<DIV>It wont do anything for the overheating.</DIV>
<DIV> </DIV>
<DIV>On your newer cars today they need a much higher pressure cap because the
run the engine temp much higher to reduce emissions. I have seen some new
Jaguars and Land Rovers that are running a 25 lb cap. As well as cooling
systems that you can not fill up correctly with out using a vacuum type
filler. Due to the fact that there will be air pockets in the cooling system
that you can not remove any other way.</DIV>

<P>7 Psi should be more than enough on these old engines. Water pump seal may
fail (as mentioned), so may the hoses and the original style radiator if you
operate under a higher pressure. Modern cars can take much higher pressures
of 20Psi or more. If your cooling system is up to scratch there should
not be a problem. i.e. clean system, radiator with enough capacity,
thermostatically controlled electric fan to keep things under control in dense
traffic and hot weather. The electric fan may not be original but when these
cars were new traffic conditions were not as demanding as in these days. It
just keeps you out of trouble at very little costs and a bit of ingenuity
(breakers yard).<BR></P>

<DIV>If you are using the alloy radiator you have a short neck cap.
Depending on the press’s app you are using you can not use a bellows type
thermostat. Because the bellows will collapse if you use anything over 7
lbs. Then the thermostat will close and the engine will overheat. <BR><BR>

<DIV>I would like to go back to Steve Byers’ comment. I am not so much
concerned about my car overheating. When the engine was rebuilt it was
thoroughly cleaned to get rid of all sludge. I run an aluminum radiator,
have built and installed air ducting for improved flow. I do not have an
electric fan.
<DIV> </DIV>
<DIV>My problem was that my engine ran cool and would take quite a while
to “warm up.” I think I was using a 165 degree (or thereabouts)
non-sleeved thermostat. Robert Shaw as I recall. So I wanted to get my
engine up to 185-190 degrees sooner. I went with one of the same AC
sleeved thermostats 82 degrees centigrade from Kees that Steve used. The
engine seems to be much happier and gets to running temp more
quickly.</DIV>
<DIV> </DIV>
<DIV>At least for my engine, a 160-165 degree thermostat keeps things cool
too long. In a perfect world I would prefer David Nock’s bellows
thermostat but with a 185-190 degree opening. Since that doesn’t seem to
be available I think I will stick with the AC unit and keep my eye on the
temp. Gauge.</DIV>

<DIV>Well I have watched this discussion on sleeved thermostats for
the last week but now I just have to say. When the sleeved thermostats
went NLA, about 45 years ago, we resorted to installing just plain old
Stant 175 degree stats and guess what ... not one complaint or comment
on running hotter or overheating and absolutely no sign of any
symptoms of overheating on my own BJ8 even in the hottest of ambient
temperatures. It just didn't happen!!! Just sayin'. M
