Bob & Mike:
=C2=A0
You both may have seen my requests on overheating of my BJ8 and the respons=
e from the group.=C2=A0 As a result, I purchased an infrared thermometer to=
determine if my water gauge was giving accurate readings.=C2=A0 The thermo=
meter gun told me that my water gauge was 30 degrees higher than the temper=
ature of the sensor attached to the block.=C2=A0 At the same time, I notice=
d my gauge will show 120 degrees at rest instead of going down to 90 degree=
s which would indicate a 30-degree high reading.=C2=A0 In May when I leave =
for cool Michigan, I will send the gauge to Nisonger to be rebuilt.
=C2=A0
I began to test the temperature of the water going through the cooling syst=
em at the inlet to and outlet from the block, inlet and outlet to the radia=
tor and the upper and lower hoses while the engine is running at idle and a=
t 2-3 Thousand rpm.=C2=A0 The chart I created to record these temperatures =
allowed me to produce observations or averages because the flow of the wate=
r is dependent upon the rpms of the engine.=C2=A0 The engine has overheated=

=C2=A0
The above temperatures are recorded at the inlet and all along the hoses.
=C2=A0
These temperatures indicate the pump is circulating water with sufficient g=
allons to cool the engine only when the engine is at high rpms.=C2=A0 At id=
le the pump does not circulate sufficient water to keep the engine cool.=C2=
=A0 This is especially true when you have been operating the engine at high=
speed and come down to 30 =E2=80=93 40 mph and stop and go traffic.=C2=A0 =
Maybe the real answer is to install an electric pump for constant cooling w=
ater?
=C2=A0
In the past week, I have installed a large Dorman coolant recovery tank and=
a new 7 psi 1 inch radiator cap because I learned that our radiators have =
a long neck.=C2=A0 Both those changes have reduced my problem of very high =
overheating and resulting boiling over. =C2=A0In addition, when my water ga=
uge shows 212 degrees the water temperature is actually 30 degrees less or =
approximately 185 degrees.=C2=A0 Also, I am not boiling over and loosing co=
olant.=C2=A0 Nevertheless, the engine water temperature is still spiking to=
210 plus degrees true when coming off highway speeds.=C2=A0=20
=C2=A0
In my review of various sites, the radiator equipment suppliers and others =
are recommending increasing the pressure in the classic car systems to 15 p=
si plus, and coolant recovery tanks =E2=80=9Cif your coolant system, radiat=
or, hoses etc. is new=E2=80=9D and therefore can hold the pressure.=C2=A0 U=
nfortunately, I have not found any maker of a 1 inch depth x 2.33 inch diam=
eter radiator cap except our 7 psi cap so I can try such a pressurized syst=
em.
=C2=A0
Another suggestion on an older discussion at the British Car Forum indicate=
d some of the Ontario car owners had switched to Evans Waterless Coolant ra=
ther than 50/50 coolant water mixture.
=C2=A0
I still have no idea why a minority of our group has overheating problems.=

Yes Bob, there is something wrong with our assumptions regarding the coolin=
g system not being "large" enough.=20
My wifes Maxima is around 300 HP and the radiator has less area than the 10=
0. Certainly it has a couple of very effective electric fans but they reall=
y don't cut in very often unless you have the AC on.
I'm suspicious of the rate of circulation but I've talked to Larry Varley a=

Anyways, after doing all the usual stuff to increase cooling, esp. on my BJ=

ines don't have a similar spacer to be improved upon, and it would be a maj=
or task to increase both the cavity's size and the pump (but I can dream).
ps. The overheating issue with Healeys is usually attributed to too big of =
an engine in too small of an engine compartment, and too little airflow. Bu=
t, the engine bay in an old T-Bird is huge by comparison--and the engine no=
