Parts for your 2022 Toyota Land cruiser-Head gasket

2022 Toyota Land Cruiser head-gasket: what it is, why it matters, and when to act

Yes, the 2022 Toyota Land Cruiser (J300 series) uses a head-gasket. Both engines offered for this model—the 3.5‑litre twin‑turbo petrol V6 (V35A‑FTS) and the 3.3‑litre twin‑turbo diesel V6 (F33A‑FTV)—are conventional alloy‑head, multi‑cylinder engines that require a multi‑layer steel (MLS) head-gasket between the cylinder block and head. This is confirmed in Toyota’s J300 Repair Manual coverage for V35A‑FTS and F33A‑FTV engines, the Toyota Electronic Parts Catalog (EPC) listings for the J300 head-gasket, and typical MLS specifications in Toyota service documentation for late‑model alloy DOHC engines.

On the 2022 Land Cruiser, the head-gasket’s job is to keep combustion pressures sealed while also separating coolant and oil galleries that run between the block and head. A healthy gasket preserves power, keeps coolant and oil where they belong, and protects the turbo V6 from overheating or cross‑contamination.

It isn’t a routine service item, there’s no scheduled replacement. Looking after it is mostly about prevention: keep the cooling system in top nick, use the correct Toyota Super Long Life Coolant and change it on time, fix any cooling leaks quickly, and never keep driving if the temperature creeps up. Correct torque procedures on any top‑end work also matter because these engines use torque‑to‑yield head bolts specified in Toyota’s repair procedures.

• Watch for tell‑tales of trouble: unexplained coolant loss, rising temps under load, hard cold starts or misfires, pressurised upper radiator hose when cold, white exhaust vapour after warm‑up, sweet smell from the exhaust, or milky residue on the oil cap/dipstick.

If a head-gasket does fail, it’s a by‑the‑book job: diagnose properly (cooling‑system pressure test, chemical block test, cylinder leak‑down, borescope if needed), remove the heads, check flatness and surface finish to Toyota’s spec, fit a quality MLS gasket, and always replace the head bolts. A trusted workshop familiar with the J300’s V6s will have the special tools, procedures, and tightening sequences from the Toyota manual to get it right the first time.

Owners who keep the cooling system healthy, use the right fluids, and avoid overheating typically enjoy a gasket that lasts the life of the vehicle—even with serious outback kilometres under the bonnet.

Popular questions

Does the 2022 Land Cruiser actually have a head-gasket?
Yes. Technical references including the Toyota J300 Repair Manual for the V35A‑FTS and F33A‑FTV engines and Toyota’s Electronic Parts Catalog list an MLS head-gasket and torque‑to‑yield head bolts for this model, confirming it’s a conventional head‑to‑block sealed design.

How long should the factory head-gasket last?
Under normal use, it should last the life of the vehicle. Most premature failures trace back to overheating, incorrect coolant, neglected leaks, or improper torque procedures during other repairs. Keep the cooling system serviced on time and don’t ignore temperature warnings.

Is a “head-gasket sealer” a good idea on a J300?
Not recommended. Sealers can gum up heater cores, radiators, and narrow coolant passages—especially on modern twin‑turbo V6s. Proper diagnosis and repair using the Toyota procedure, MLS gasket, and new head bolts is the reliable fix.
