His Yellowness does not have a heater on his car. Can someone put up a pic?

Why? I understand there may be some safety regulations requiring them if someone is stranded in freezing conditions, but a 7? The engine is usually warm enough to keep you toasty. Once the 7 is tagged and on the road, who needs it? Does anyone actually use the heater?

Engine porn!

Exactly. Things like that. Modern OAT coolant has such good anti corrosive additives it can clear rust out of an Iron block.

If your coolant is 5 years old, change it. Think of it like oil or brake fluid, it needs refreshing at intervals too.

No advantages over the coolant reccomend by Ford or Caterham. The issue is the potential for deleterious affects on chemically incompatible non-OEM components throughout the system. Generally, all coolants cool the same, with alternatives like gells, water wetter, etc. being the exception, standard long life coolants differ in how they interact with the components they are in contact with. They work together as a system. When a coolant is recommended by an OEM, there is usually a materials compatability issue. If a coolant of any kind looses its effectiveness its likely something has happened to that coolant to get contaminated and change its properties. This is why a good flush is necessary. These 7s tend to sit for long periods leaving the coolant ample condition to sit and eat away on a rubber seal or gell and cryatalize from a remnant of an invasive element introduced like an additive or previous coolant or some other corrosion. Getting a clean slate baseline to work with from a flush and refill with an OEM approved coolant is your starting point for troubleshooting the other issues. Also, just plan on making your coolant system a regular maintenance item. Coolants, like brake fluid, go bad over time and contamination, not from use.

Drain, check liquid for anomalies, do a boil test on the thermostat in the kitchen, run a flush solution without thermostat (with heater open), drain and run several water flushes (with heater open), reinstall all and fill with a premixed coolant you will stick with and never mix with anything else. Test or eplace the expansion tank cap.

anything new?

I will try to be more helpful I measured the nose lower skirt on an original Lotus S2/3 and from a reproduction made by DSK, from the period. They were both very close. LOTUS DSK

Then that bottom edge should have reached the frame. They cut it short. I would ask for another, with corrections. Or take the opportunity to fab a hinge Piano hinge
