This whole running hot things seems to be a process of chasing little things.
My MGA ran hot after its rebuild. It ran hot before its rebuild, but it had
an excuse then...the engine was full of crud and the radiator needed to be
recored. I ended up doing several things, including:
1. Installing a shroud (from Moss) around the water pump fan/radiator core.
2. Installing a piece of fiber material (from Moss) to the underside of the
bonnet to keep the air from passing over the top of the radiator. (The
factory piece had fallen off long ago.)
3. Installing a restrictor sleeve (from Moss) in in the thermostat housing to
replicate the effect of the earlier bellows style thermostats.
4. Installing insulating foam rubber (from Home Depot) between the forward
radiator shroud and the radiator body to keep air from flowing past the
radiator in that area.
The combination of these remedies seemed to do the trick.

Bob,
I'm enjoying it too. Everyone is addressing everything that I have
already
tried but none has come up with an answer to what the dia. of the
water pump
pulley should be???
I assume no one has found my chair?
I'm
hoping the Distributor rebuild will be the answer. If the problem ever gets
solved I will definately report back with the cure.
Really enjoyed you clubs
Conclave.
Ron

Ron,
I'm enjoying the
dialogue regaarding the engine temperature on your tri-carb. I
sincerly hope
a definitive answer surfaces.
My BT7 Tri-carb
has had the same issue for
years. I run fine in town or at moderate highway
speeds, but get it above 65
MPH andthere goes the temperature. On some
longdistance runs I've run for
hours at above 212, No problems but I
just don't like it. It definitely is
worse on a sunny day, of course my car is
black so it maybe absorbing heat
from the sun. Your car is white so there is a
difference.
On my radiator
shrouding I've addedsealent to prevent any air from getting
around the
radiator, helps but not significant. I do not have OD issues, running
Redline.
Good luck solving the heat and please share the result.
Bob
