About this Coolant Hose

The REIN AUTOMOTIVE CHR0391 coolant hose carries coolant between the engine, radiator, heater core or expansion tank. Hoses age from heat and pressure, and a single failed hose can empty the cooling system and overheat the engine within minutes.

Frequently asked questions

What are the signs of a failing coolant hose?

Coolant drips or dried coolant residue, a sweet smell, a hose that feels soft, swollen or cracked, a low-coolant warning, or rising engine temperature. Squeeze hoses when the engine is cold: a healthy hose feels firm but flexible.

What should I replace along with the hose?

Replace any clamps, O-rings or seals at the connections. Many European cars use plastic quick-connect fittings that become brittle with age, so inspect neighbouring hoses and fittings while the system is drained.

What coolant should I use?

Use the coolant type your car's manufacturer specifies, mixed to the correct ratio. Mixing incompatible coolants can cause deposits and reduce protection.

Can I replace a coolant hose myself?

Usually, yes. Let the engine cool completely before opening the system, catch and dispose of old coolant properly, and bleed the air out of the system afterwards following your car's procedure; trapped air can cause overheating.

How do I make sure this coolant hose fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
