Volvo 240 Heater Hose Replacement

Replace a worn or leaking HVAC heater hose with this URO molded heater hose for the 1990-1993 Volvo 240. It is shaped to match the OE routing for the cylinder head to heater connection, helping preserve factory fit and service access on Volvo 240 upper heater hose applications.

  • Fits 1990-1993 Volvo 240, upper cylinder head to heater
  • Molded to OE heater hose shape for correct routing and appearance
  • EPDM construction resists engine heat, ozone, and electrochemical degradation
  • Temperature rated from -40°F to 275°F (-40°C to 135°C)
  • Guaranteed fitment for the listed application
  • URO part number 463524 for direct replacement searches

Application Details

This HVAC heater hose is built for the upper heater circuit on the Volvo 240, connecting the cylinder head to the heater system. The molded profile supports a clean installation in the original hose path and helps maintain proper coolant flow through the heater core circuit. If you are searching for a Volvo 240 heater hose, upper cylinder head to heater, or URO 463524, this part matches the listed fitment.

This part cross-references URO (e.g., URO-002856) for the same application.

Common Replacement Reasons

  • Coolant seepage at the heater hose
  • Cracking, hardening, or swelling from age and heat
  • Restricted heater performance from a deteriorated hose
  • Incorrect routing or fitment on a previous replacement hose
  • Visible wear from ozone or electrochemical breakdown

Installation Notes

Verify the hose routing against the original Volvo 240 upper heater hose before installation. Inspect adjoining clamps, fittings, and nearby coolant lines for wear or corrosion, and confirm the system is properly filled and bled after service. The molded shape is intended to simplify placement in the OE path on 1990-1993 Volvo 240 models.

Quality Assurance

URO lists this heater hose with guaranteed fitment and a 24-month unlimited mileage warranty. The EPDM material is specified for resistance to engine heat, ozone, and electrochemical degradation, with a temperature range suitable for typical cooling-system service conditions.
