Engines With Dry Sump Tank - Except Csr 200 / 260; Engines With Dry Sump Bell Tank And Swirl Tower - Csr 200 / 260 Models Only; Supercharger Oil Level Checking And Maintenance (For 620 R Only); Coolant Check & Top-Up - Caterham Seven Owner's Handbook Manual

Engines with dry sump tank
Start the engine and run it until the normal
operating temperature achieved (90-100°C). Turn
the engine off, wait 30sec and take reading from
the dip stick, you should be within the hot range.
Top up the oil if required and repeat.
NOTE: With this system the oil level must be
checked within one minute of the engine being
switched off otherwise the oil will start to drain
back into the engine and a false reading will be
obtained. Should this be the case restart the
engine again and let it run for approximately
one minute before repeating the checking
procedure.
Supercharger oil level checking and
maintenance (For 620 only)
To check the oil level on the supercharger system
requires the engine to be running and held between
2 – 3000rpm. The correct oil level is between the
min and max markings of the dipstick measured
with the thread of the cap fully engaged. Check the
oil system regularly.
IMPORTANT!
Always keep the oil level between minimum and
maximum.
Overfilling the canister may cause oil leaks from the
oil canister and too little may cause damage to the
supercharger.

Coolant check & top-up
The coolant level should be checked weekly when
the system is cold and topped up with appropriate
coolant (see technical data). Top up to the 'MAX'
mark shown on the exterior of the reservoir. If the
level falls appreciably during a short period;
suspect leakage or overheating and contact
Caterham to arrange for factory trained technician
to examine the vehicle.

Anti-freeze

The anti-freeze content of the coolant must be
maintained all the year round. Caterham use Millers
Alpine Red and Ford Superplus premium (ready
mixed), however, if a water/anti-freeze mix is
substituted for any reason a minimum of 50% anti-
freeze is required. To ensure that its anti-corrosion
properties are retained, the anti-freeze content
should be checked by Caterham once a year. The
coolant should be completely renewed every four
years.
WARNING!
•
DO NOT use anti-freeze to any specification
other than that recommended (see technical
data: recommended fluid specification).
•
DO NOT add rust inhibitors or other additives
to the coolant – these may not be compatible
with the coolant or engine components.
•
DO NOT remove the reservoir cap when the
cooling system is hot – escaping steam or
water could cause serious injury.
