Buying Cooling System Parts for a 1978 Fiat Brava
On this vehicle, the cooling system system keeps operating temperature in the narrow band the engine was designed for, from radiator and water pump to thermostat and hoses.

- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.

Frequently Asked Questions
How many cooling system parts fit the 1978 Fiat Brava?
Our catalog currently lists 37 cooling system parts for the 1978 Fiat Brava across 7 subcategories and 12 brands, covering both the 1.8L L4 and the 2.0L L4. Each part is matched to the engine(s) it fits.
Do cooling system parts differ between 1978 Fiat Brava engines?
Yes. Every cooling system part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of cooling system problems on a 1978 Fiat Brava?
Common symptoms include a rising temperature gauge in traffic, sweet-smelling steam, crusty deposits around hose clamps, or a heater that blows cold. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1978 Fiat Brava was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 1978 Fiat Brava?
First match the engine — each row shows which engine(s) the part fits. Then replace coolant with the exact specification the manufacturer calls for — mixing chemistries can gel and block small passages. The notes column carries position and trim qualifiers where they apply.
