Keep an eye on fluid levels, don’t rev the engine above 3000 rpm until the oil temperature has come up to at least 60 degrees. I think that’s about it.
If I keep an eye on the fluid levels and it is dropping, what can be done and why can't that be done now to stop a future HGF?

If the coolant starts to drop then in the short-term top it up to the correct level, but you need to investigate where the coolant is going, but what ever you do don’t let the expansion tank empty completely.

The other thing to note is not all HGF go in a big steamy noticable way. I acquired my TF unknowingly complete with a HGF and even then had it a month before I spotted the HGF!

OK, all of the above, Fluids checks etc,etc.

Also as Chris says DO NOT take above 3k revs till engine warm, and also IMHO its just as important to let the engine `Warm down` slowly, as well as warm up.

If you have been for a long run and engine is Very hot just let the engine idle for a minute or so before switchig off, just to let the Red hot water in the Head/block to be removed!., one of the reasons given for HGF is `heatsoak`, or localised boiling, this is when the heat from the engine is transfered to the coolant, but as the waterpump is not running (engine off), the water gets much hotter than normal, the hotter the water the greater the pressure!.

K-series HGFs seem to fall into 3 catagorys....

1, water to oil.
2, Oil to water.
3 Water escapes externally.( the big clouds of steam one)!.

When you have HGF no 3, the coolant allways escapes from the same place at the corner of the head by the alternater, this seems to be where the water gets the hottest, so could be the reason why the gaskit fails in this same place all the time!.

I know Dr Bell was working on a `Pump overrun`, which by the addition of an electric pump and timer would allow the water to circulate after engine switch off to remove this Super heated water thus meaning less chance of `Heatsoak`.
Think I am right in saying Lotus fitted this system to some of their Ks, to help prevent the `Evil` HGF.
