HOWO Intercooler Hose WG9730530011 for T7H / Sitrak C7H (MC11 MC13)

The WG9730530011 intercooler intake hose is the high-temperature silicone charge-air hose that connects the turbocharger outlet to the intercooler inlet on SINOTRUK heavy trucks. It carries pressurised air at roughly 150–200 °C into the intercooler, where it is cooled to 60–80 °C — raising air density and improving combustion efficiency.

– OEM No.: WG9730530011 (this unit is marked WG9730530011/1)
– Application: HOWO T7H / TH7 / N7W, Sitrak C7H / C5H
– Compatible engines: SINOTRUK MC11 / MC13, WEICHAI WP10 / WP12 / WP13
– Material: multi-layer high-temperature silicone, red, corrugated bellows body
– Heat resistance: continuous 180–200 °C, short-term peaks up to 250 °C
– Ends: aluminium flange rings with locating pin holes, clamp-on fitting
– Layout: 90° elbow, suits the high-mounted intercooler layout

The corrugated bellows section absorbs engine vibration and chassis flex under heavy-duty operation. Typical failure mode is surface cracking from heat ageing, which shows up as boost leakage, black smoke and lost power — check by pressurising to 0.3 MPa and looking for bubbles.
