David, thanks for your thoughts, but I'm afraid you misunderstood. My
radiator is not a POS Chinese item like the 6-bladed fan that broke and
damaged my original radiator. The radiator Moss sent me as a replacement is
a stock radiator made by the Coventry Radiator Presswork Co., Ltd. with all
of the same identification and markings as the original except that the
serial numbers are not the same, of course.
Admittedly, the radiator may be my problem, but visibly there is nothing
wrong with it and I had no reason to have it tested and inspected before I
installed it in March 1996. The tubes as I can see them through the filler
neck are all clear with no signs of sediment or damage. When I drained the
coolant a few weeks ago, it was also clear with no evidence of rust, etc. I
reused the coolant and poured it back through a paint strainer. There were
no particles visible. The coolant is a year old.
Certainly re-coring the radiator with larger capacity tubes should improve
cooling, but that ain't cheap and it hasn't made it to the top of my
priority list yet. It's just peculiar to me that the sleeved thermostat
made no difference in the stabilized running temperature as compared with
the non-sleeved one.

Remember that the radiator is the main part that controls the
high engine temperature. The thermostats main job is to get the engine up to
operating temp as soon a possible. Then once the thermostat is open in no
longer is an issue in the cooling system other that the bypass. The bypass
is there to allow the coolant to circulate when the thermostat is closed,
and if it is not blocked off when the thermostat is open approx 20% of the
coolant will not go thru the radiator.
I would bet that your problem is that P.O.S chinese radiator
that you have is your problem. I have had many customers install these
radiators in many different cars from Healey's to MG's and Triumph's and all
of them have had heating problems. I have fixed every one of them by
installing one of my special radiator cores that we use.
