Car Cooling System Specification Example for Courier Fleets: Reinforced Build
Car Cooling System Specification Example for Courier Fleets: Reinforced Build
This is a worked specification for car cooling system in a reinforced build programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The reinforced build version exists because the duty cycle on courier fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.
Example specification
| Item | Car Cooling System |
|---|---|
| Application | Courier Fleets |
| Version | Reinforced Build |
| Base material | Sintered Metal |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | zinc plated |
| MOQ | 1,000 pieces per specification |
| Sampling | 14 working days, 3 days per revision |
| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Sintered Metal, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- CNC machining
- sintering
- gravity casting
- rubber vulcanisation
- assembly line testing
- robot welding
Where this example applies
Programmes that run reinforced build most often specify this build for courier fleets. Related applications include three-wheelers, off-road bikes, fleet maintenance, assembly programmes, municipal fleets.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What testing is included?
Standard lots ship with dimensional and hardness reports. ECE R90 documentation is issued with the shipment when your market requires it.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
