Quick answer
Fleets, workshops and facilities usually buy coolant as concentrate or premix in drums (about 200 L / 55 gal), IBC totes (about 1,000 L / 275 gal) or bulk tanker delivery. Standardise on the specifications your vehicles or equipment require, decide premix vs concentrate, and compare delivered price per litre including packaging and disposal.
Key takeaways
- Match the coolant spec to your fleet’s OEM requirements before price.
- Premix avoids dilution errors; concentrate saves freight and storage.
- Ask suppliers about testing, take-back and disposal services.
General information. Confirm the exact fluid, equipment and qualification with your hardware or CDU supplier before specifying.

Choosing the specification
- List the coolant specifications required by each vehicle or engine type in your fleet. Heavy-duty diesel engines often need specific HD coolants: see heavy-duty diesel coolant.
- Where possible, standardise on one or two products that meet all required approvals.
- Understand chemistry differences: OAT vs HOAT vs IAT.
Premix or concentrate?
Premix (typically 50/50) removes dilution errors and water-quality issues. Concentrate lowers freight and storage per litre of protection but needs good-quality water and correct mixing. See premix vs concentrate.
How to compare quotes
- Price per litre of ready-to-use coolant, not per litre of product.
- Delivery, pallet and deposit charges.
- Approvals and data sheets for each product.
- Testing support (test strips, lab analysis).
- Waste coolant collection and recycling. See coolant disposal.
