Will it fit your car
With coolant lines, the engine alone is not enough. The routing depends on the body, the equipment level and whether the car has an additional radiator — the same M274 in two models can carry a different pipe number.
That is why we do not publish a model list here that we have not verified in the catalogue. The number A2742031382 decides.
How to check: the number is printed along the pipe in the form A2742031382/ZGS001. Compare it with yours.
Not sure? Send us a photo of your pipe and your VIN — we check it and confirm before shipping.

What this part does
The pipe carries coolant between the engine and the cooling system. It keeps the circuit sealed under pressure across the full working temperature range.
On these engines the pipes are formed for one specific route through the engine bay. A universal hose rarely sits correctly and ends up chafing against the ancillaries — so it is the matching number that counts, not the diameter alone.
When it needs replacing
| Symptom | What to look at |
|---|---|
| Coolant loss with no visible puddle | a leak that evaporates on the hot engine, a faintly sweet smell |
| Deposits and streaks at the connectors | white or pink film around the quick coupling |
| Cracked or hardened body | hairline cracks at the bends |
| Leaking quick coupling | worn O-ring or broken clip, it weeps after every warm-up |
| Engine overheating | after ruling out the thermostat, the pump and the radiator |
Before you order: rule out the expansion tank, its cap and the thermostat first. A leaking pipe leaves a characteristic deposit around the connector.

Questions we get most often
Are the O-rings and clips included? The part comes as it left the vehicle. Treat the quick-coupling seals as consumables — with a used pipe it is always worth fitting new ones.
Is a pipe that has years on it still any good? The plastic in these lines ages more slowly than ordinary rubber, and we inspect every piece for hairline cracks at the bends. If you have doubts, write to us before buying.
