A reliable heating system and a stable engine temperature are fundamental to driving comfort and vehicle health. The heater hose assembly, identified by OE number?12590279, is a crucial link in this system, circulating hot coolant between the engine and the heater core to provide cabin warmth and aid in engine temperature regulation. A failure of this assembly can lead to a loss of cabin heat, engine overheating, and dangerous coolant leaks.

Our direct replacement for?OE# 12590279?is engineered to restore the integrity of your vehicle's cooling and heating system, ensuring dependable performance in all climates.

Q: Do you provide installation guidance for brake system work?

Yes. We offer comprehensive technical sheets with torque values, bleeding procedures, and access to our technical support team for complex installations.

Q: Why choose your replacement over cheaper alternatives?

Our tubes use certified CuNiFe material that will not rust internally, while many budget options use coated steel that corrodes from inside out. The safety difference is significant.

Q: Can I repair just the corroded section of brake line?

No. Industry safety standards require complete tube replacement between fittings. Partial repairs create weak points and compromise system integrity.

Q: What is your typical lead time for production and shipment?

For this specific part, we can often ship sample or small orders within 7-10 days. For larger production runs, the standard lead time is 30-35 days after order confirmation and deposit receipt.

Q: What is your Minimum Order Quantity (MOQ)?

We offer flexible MOQs to support new business. For this standard OE part, the MOQ can be as low as 50 pieces. Custom parts may have different requirements.

Q: Do you offer samples for quality verification?

Yes, we encourage potential partners to test our product quality. Samples are available for a modest cost. Contact us to arrange a sample order.

Q: Are you a factory or a trading company?

We are a?manufacturing factory?(NINGBO JIATIAN AUTOMOBILE PIPE CO., LTD.) with IATF 16949 certification. This means we produce the parts ourselves, ensuring quality control and competitive pricing.
