Parts for your 2017 Honda Cr-v-Head gasket

2017 Honda CR‑V head gasket — fitment, purpose and practical servicing tips

Technical sources including the Honda CR‑V (2017) workshop manual (Engine/Cylinder Head sections on Honda Service Information), the Honda electronic parts catalogue, and industry repair databases confirm the 2017 Honda CR‑V’s petrol engines — the 1.5‑litre turbo L15B7 and the 2.4‑litre K24W — are built with a multi‑layer steel cylinder head gasket. So yes, a head gasket is absolutely fitted to this model.

On this CR‑V, the head gasket sits between the aluminium cylinder head and the engine block, sealing three critical paths at once: high‑pressure combustion, coolant, and engine oil. Its job is to keep compression tight in the cylinders while stopping coolant and oil from wandering into places they shouldn’t. Honda uses a multi‑layer steel (MLS) design here because it copes well with heat cycles, boost pressure (on the 1.5T), and the different expansion rates of alloy and iron.

This isn’t a routine service item, it’s replaced only when there’s a fault or when the head has to come off for other engine work. That said, looking after the cooling and lubrication systems goes a long way to keeping the gasket happy.

• Tell‑tale signs it’s failing: persistent overheating, white exhaust vapour once warm, unexplained coolant loss, pressurised hoses when cold, milky oil on the dipstick or under the oil cap, or a sweet smell from the exhaust.
• Simple checks during regular servicing: verify coolant level and colour under the bonnet, inspect for external leaks, run a cooling‑system pressure test if levels keep dropping, and consider a combustion‑gas test in the header tank if symptoms appear.

If replacement is needed, it’s a professional job. The cylinder head should be checked for flatness and surface finish, new head bolts (torque‑to‑yield) are required, and the factory torque sequence and angle settings must be followed. Timing on the chain‑driven camshafts has to be set correctly before reassembly. An OEM‑spec MLS gasket is strongly recommended.

• Prevention tips: avoid overheating (it’s the head gasket’s worst enemy), use the correct Honda Type 2 coolant, keep oil changes on schedule, and fix cooling fans, thermostats or minor leaks promptly.
• After any head work: replace coolant, bleed the system properly, change the oil and filter, and recheck coolant level over the next few hundred kilometres.

Looked after well, the head gasket on a 2017 CR‑V should deliver a long, drama‑free life, whether it’s the torquey 1.5T or the relaxed 2.4 under the bonnet.

Do the 1.5T and 2.4 engines use the same head gasket?

No. Both use an MLS gasket, but each engine family has its own design and part specification. They’re not interchangeable, so parts should always be matched to the exact VIN and engine code.

What are common signs of a blown head gasket on a 2017 CR‑V?

Think repeated overheating, white exhaust vapour once warm, unexplained coolant loss, hard upper radiator hose from cold, or creamy residue on the oil cap. A cooling‑system pressure test and a combustion‑gas test in the coolant can confirm what the eyes and nose suspect.

Will a stop‑leak product fix a leaking head gasket?

It might mask symptoms briefly, but it’s not a proper repair and can clog small passages like the heater core. A correct fix involves head removal, inspection, a new MLS gasket and bolts, and following Honda’s torque procedure.
