4. FAQ

Q: What are the main material properties of gasket kit part number 4Q‑5139?
A: Part number 4Q‑5139 is constructed from FKM fluoroelastomer rubber and reinforced composite fiber sheet. This material combination delivers outstanding coolant resistance and thermal stability under continuous high‑temperature cooling‑system working status.

Q: What visual appearance do sealing components of part number 4Q‑5139 show?
A: For part number 4Q‑5139, rubber sealing pieces show smooth jet‑black surface, and composite fiber gaskets display dark charcoal‑grey matte fibrous texture without extra paint or surface treatment.

Q: Where is this radiator gasket kit installed on the equipment?
A: This gasket kit is fitted between radiator core and upper water tank, forming closed sealing joints inside the vehicle cooling assembly.

Q: What are the core functional features of this gasket set?
A: It blocks coolant leakage from radiator connecting joints, meanwhile reducing dust and grit from invading the internal radiator structure.

Q: What visible early signs indicate gasket replacement is needed?
A: Watch for tiny coolant traces around radiator connection joints and frequent drop of coolant level inside expansion tank.

Q: How effectively can these gaskets compensate for minor surface unevenness on assembly flanges?
A: Graphite and fiber layers possess favorable compressibility. They can fill tiny gaps on mating surfaces and block transmission oil seepage caused by minor machining defects of transmission housings.

Q: What convenient benefits can maintenance staff obtain by adopting this integrated gasket kit?
A: All gaskets and adjusting shims required for full transmission housing overhaul are packed as one set. Technicians do not need to cut gaskets manually or collect scattered spare parts, effectively shortening on-site repair time.
