Here ya go. Very simple 2 in stepper movement gauge with 2 switches to

Yes, no doubt that idling after a high speed run when the engine was =
working hard with increased losses is the worst situation for our cars. =
Another technique to help the "reserve" is to install an overflow =
recovery tank that ensures you start off with a full header tank. This =
is a relatively simple project and works well.

WT - Smiths std gauge

OT- oil temp at filter

TH - top hose water temp

5 Blade TX fan; oil cooler; EWP electric water pump - manually switched; =
160F thermostat - agree with Michael above; rad recovery. As per Harold =
have 2 x 3/16 holes in thermostat; AL finned sump.

Oil takes longer than we think to get close to operating temp at least =
30 min but depends on ambient.Often long after the stat. opens

EC and OT rise rapidly when no airflow as MS describes. rg thinks that =
we under estimate the cooling effect of cruising airflow on the actual =
engine block surface. Airflow is somewhat limited as a big chunk of =
metal obstructs and no easy exit. Often wondered if an extractor fan =
would help - hence the louvres on the hood and sides to get the hot air =
out for competition cars. My car runs badly when EC is above 155F - =
becomes too rich for the inlet air.

Use the EWP when approaching traffic as above - does not reduce temp, =
but seems to prevent further increases. Important to anticipate. EWP is =
really good for controlling heat soak after cutting the engine.

Recently removed an electric rad pusher fan as no real benefit and an =
obstruction to incoming air. Rad inlet deflectors are important
