Mitsubishi Endeavor Radiator Coolant Hoses

Mitsubishi Endeavor Radiator coolant hoses

Radiator coolant hoses for your Mitsubishi Endeavor start at $13.95, with 13 options in stock from Dayco, Gates, and ACDelco. These hoses carry coolant between the engine and radiator to regulate operating temperature. When a hose cracks, collapses, or leaks, coolant loss follows quickly — leading to overheating that can cause serious engine damage within minutes.

Signs your Mitsubishi Endeavor needs a new radiator coolant hose

  • Visible coolant puddle or wet spots under the front of the vehicle after parking
  • Sweet smell of antifreeze coming from the engine bay while driving or after shutdown
  • Temperature gauge climbing higher than normal or spiking toward the red zone
  • Soft, spongy, or visibly cracked hose when squeezed during a cold inspection
  • Low coolant warning light or reservoir level dropping repeatedly without an obvious external leak
  • Steam or white vapor rising from under the hood, especially near the radiator or engine inlet

Which radiator coolant hose should you buy for your Mitsubishi Endeavor?

The two main decisions are position — upper or lower — and construction material. The upper hose runs hotter and handles higher pressure pulses, while the lower hose must resist collapse under suction. Material and reinforcement layers determine how long a hose lasts and how well it handles heat cycling over time.

OE-spec EPDM rubber (upper)
Best for
Direct replacement for the hot-side hose from engine to radiator
What you get
Ethylene propylene rubber with fabric reinforcement; resists heat, ozone, and coolant chemistry; shaped to fit without trimming
OE-spec EPDM rubber (lower)
Best for
Direct replacement for the suction-side hose from radiator to water pump
What you get
Spiral-wound wire insert prevents collapse under pump suction; pre-molded bends match factory routing
Silicone (performance/heavy-duty)
Best for
High-mileage vehicles, tow rigs, or builds that run higher coolant temps
What you get
Three- to four-ply silicone handles a wider temperature range than standard rubber; longer service life; typically sold in blue, red, or black
Universal cut-to-fit hose
Best for
Odd routing or discontinued OE shapes on older Mitsubishi Endeavor models
What you get
Straight or slightly curved EPDM hose sold by the foot; requires proper clamp selection and careful length measurement — best left to experienced DIYers

Replacing radiator coolant hoses on a Mitsubishi Endeavor

Easy⏱ 45 minutes – 1.5 hoursDrain pan (at least 2-gallon capacity)Flathead or Philips screwdriver (worm-drive clamps)Hose clamp pliers or spring-clamp toolCoolant funnel or spill-free adapterFlashlight for inspecting hose routing

Drain the cooling system into a pan, loosen the clamps at each end of the hose, and twist the hose free — penetrating oil on the fitting helps break the seal without damaging the radiator neck. Slide the clamps onto the new hose before seating it, position clamps past the bead on each fitting, and tighten securely. Refill with the correct coolant mixture, run the engine to operating temperature, check for leaks, then top off as needed after burping any trapped air.

Frequently asked questions

How much does it cost to replace radiator coolant hoses on a Mitsubishi Endeavor?
Parts alone start at $13.95 for a single hose on your Mitsubishi Endeavor. Professional labor typically adds one to two hours of shop time on top of the part cost. Replacing both upper and lower hoses at the same service visit saves labor and avoids a second coolant drain-and-fill, so most shops recommend doing them together.
How long do radiator coolant hoses last on a Mitsubishi Endeavor?
Most OE-quality EPDM hoses last roughly four to ten years or a wide range of miles, depending on coolant condition and heat cycling. Degradation accelerates when coolant goes unchanged too long, because depleted inhibitors raise acidity that attacks rubber from the inside. Inspect hoses at every coolant service — squeeze them; a hose that feels hard, sticky, or mushy should be replaced.
Can I drive my Mitsubishi Endeavor with a leaking radiator hose?
No — even a small leak can drain the cooling system within a few miles. Running a Mitsubishi Endeavor low on coolant causes rapid overheating, and sustained overheating warps cylinder heads or cracks the engine block. Pull over safely as soon as a leak is confirmed, let the engine cool completely, and do not remove the radiator cap until it is fully cold.
Should I replace both the upper and lower hose at the same time on my Mitsubishi Endeavor?
Yes, in most cases. Both hoses are the same age and exposed to the same heat cycles, so if one is near the end of its life the other usually is too. Replacing them together means one coolant drain, one refill, and one bleed — saving time and avoiding a repeat job a few months later when the second hose fails.
What coolant hose clamp type should I use on a Mitsubishi Endeavor?
Use the clamp style that matches the original design — most vehicles use worm-drive screw clamps or spring-tension clamps. Spring clamps are preferred because they self-adjust as the hose softens with heat cycles; they rarely over-tighten or cut into the hose. Avoid cheap unlined worm-drive clamps on soft silicone hoses, as the band edge can bite into the material and cause slow leaks.
Do I need to bleed the cooling system after replacing a radiator hose on a Mitsubishi Endeavor?
Yes. Any time the cooling system is opened, air can become trapped in the heater core, thermostat housing, or engine passages. Air pockets cause localized overheating and inaccurate temperature gauge readings. After refilling, run the engine with the heater on full heat and the cap off or a bleed valve open until coolant flows steadily and no bubbles remain.
