Within Plant & Agriculture, Coolant covers the engine coolant and antifreeze fluids used to maintain operating temperature in plant, agricultural, and commercial-vehicle engines — covering ethylene-glycol coolants (the traditional plant and commercial standard), propylene-glycol coolants (where ethylene toxicity matters — agricultural environments, drinking-water proximity), Organic Acid Technology (OAT) coolants for modern engines, Hybrid OAT (HOAT) coolants, and the matching coolant additives (corrosion inhibitors, water-pump lubricants, cavitation-prevention additives) used in coolant-system service.
Parts for Machines supplies engine coolants across the trade and professional ranges, covering both pre-mixed (ready-to-use 50:50 dilution with deionised water) and concentrate (requiring on-site dilution) variants.
We are an authorised distributor and seller of Shell, Castrol, and Q8 across the engine coolant range — Shell offers the broadest selection of plant, agricultural, and commercial-vehicle coolants (including specific OAT-and-HOAT formulations matched to engine OEM specifications). Castrol covers the trade-grade automotive and light-commercial coolant range. Q8 extends the range with workshop and fleet-grade ethylene-glycol coolants.
Product pages list the coolant chemistry (ethylene-glycol IAT / Inorganic Acid Technology, OAT, HOAT, propylene-glycol), the colour (pink, blue, green, yellow, orange — colour conventions vary by chemistry but always check the chemistry rather than colour for compatibility), the freeze protection (typical -37°C for 50:50 dilution; lower for higher concentrations), the OEM specification approvals (e.g., MB 325.5, ASTM D6210, John Deere COOL-GARD, Caterpillar ELC), the supplied form (pre-mixed or concentrate), and the container sizes available (typical 1L, 5L, 25L, 60L, 205L drum). Always match the coolant chemistry to the engine — mixing IAT and OAT coolants causes precipitation and corrosion; OAT-only engines require OAT-only coolant. The OEM specification approvals are listed on every coolant product page; refer to your engine manufacturer's coolant specification before topping up or refilling.
