4.6 liters / 1.2 gallons
This is how I do it (expansion tank cars):
Other folks have you fill the system via the upper radiator hose; this is totally unecessary (not to mention a PITA) and puts undo wear on the hose. However, if you prefer this method, feel free to use it.
If your car is having an air bubble issue, a common trick is to drill a small hole into the thermostat, which allows for internal air bleed-
Not keeping up with timely coolant flushes can lead to internal cooling system corrosion. Flush the coolant every 30,000 miles or every 2 years, whichever comes first, if using G11; if you have switched to a G12 variant or G13, the flush interval is increased to 4 years.
If you would like add an expansion tank to your system you will need the following parts: newer style radiator, hose from radiator to expansion tank, expansion tank, hose from expansion tank to coolant return pipe and a coolant return pipe.
The radiator cooling fan operates under the following conditions:
Cabriolets up to 1987 with A/C do not have two-
Radiator Cooling Fan Won't Turn On
Check the fan motor and thermo switch by completing the following steps.
Disconnect the thermo switch connector.
Using a jumper wire, make a connection between terminals (2-
Does the fan run? Yes: The thermo switch is faulty and needs to be replaced. No: Proceed to step 4.
Check for voltage at the thermo switch connector (red wire). Is there voltage? Yes: Proceed to step 5. No: Check fuse #1.
If the thermo switch is good and the fuse is good, the thermostat (in the water pump housing) may be faulty. 1988-

Replace the radiator fan switch. 1988-

If you desire to rid your car of as much plastic as possible, all aluminum replacement radiators can be found on eBay
The purpose of the cards is to direct airflow through the radiator with little air escaping around the radiator; this enables the cooling system to work more efficiently. New OEM baffles are no longer available. The cards were originally made out of cardboard which, over time, disintegrates. Rather than sourcing used cardboard radiator baffles, you can easily make new, long-

Only Cabriolets with JH engines in North America have oil coolers; "why?" remains to be answered. In Europe, only the EG, JH, 2H, DX and KT engines came with oil coolers.
If your Cabriolet is without an oil cooler, you can install the OEM cooler (additional coolant hoses will be needed), or an aftermarket cooler that utilizes air, rather than coolant, to dissipate heat from the oil.
