Triumph 1300/Toledo/1500

Additional Notes

• The Triumph 1300 and 1300 TC, both produced from 1965-1970, share an identical cooling system capacity of 3.5 liters, indicating a common engine cooling architecture across the standard and twin-carburettor variants of that displacement.
• The 1500 and 1500 TC variants, covering 1970-1976, carry a cooling system capacity of 4.8 liters, a figure 1.3 liters greater than the earlier 1300-series models, reflecting the increased thermal management demands of the larger engine.
• The Toledo 1300, despite sharing its production years of 1970-1976 with the 1500-series models, carries a 4.8-liter cooling system capacity rather than the 3.5-liter figure associated with the earlier 1300 and 1300 TC, pointing to a different cooling system design in the Toledo body platform.
• All three Toledo variants — the 1300, 1500, and 1500 TC — share the same 4.8-liter cooling system capacity across the 1970-1976 period, meaning the Toledo platform used a uniform cooling system volume regardless of engine displacement or tune.
• All seven configurations across the 1300/Toledo/1500 range are specified under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty or high-stress service scenarios.
• The 4.8-liter figure appears across five of the seven listed configurations, spanning both the 1500-series and the full Toledo range, making it the dominant cooling system capacity within the Triumph 1300/Toledo/1500 lineup from 1970 onward.
