So my 2.3t build is in a 75 Triumph Spitfire, it currently has a Volvo coolant expansion tank that probably holds about 1qt. I've been told I need a bigger tank. Any suggestions on sizes, or any aftermarket or junkyard tanks that might work? Space is limited.
Assuming its the rad expansion tank.... Told by who? Is there a problem? If the Volvo tank functions and keeps the fluid off the ground why bother. These engines run cool if you have enough rad and airflow going thru it.
