FAQs

By machine and circuit where it's a catalogue fitment — model and serial — and by measurement where it isn't: core dimensions, connection threads and positions, and mounting, photographed and confirmed via Ask Simon or WhatsApp. Bespoke and obsolete coolers are matched from exactly that information against the manufacturing records.

Separate circuits, separate coolers: hydraulic heat passes through its own cooler, and a blinded core, internal fouling or a failed bypass shows as hot oil on a healthy engine gauge. Blow the cooler's fins clean first — the cheapest fix — then check flow and bypass before condemning hardware.

On machines with liquid-cooled oil coolers, suspect the cooler before the head gasket: an internal failure cross-contaminates both circuits, and it's a far cheaper repair than the gasket everyone fears. Treat it as urgent either way — emulsified oil lubricates nothing — and flush both circuits properly after the fix.

Often: the same logic as radiators applies — sound construction with a failed core or seam can be rebuilt economically, and the manufacturing base behind the range handles repair, recore and remanufacture as well as replacement. Photographs and measurements via WhatsApp settle which route the unit deserves.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Oil Cooler

Oil coolers are the cooling the temperature gauge doesn't show: the heat exchangers that hold engine oil, transmission fluid and hydraulic oil inside their working range on the machines, trucks and vehicles whose duties cook lubricants long before coolant complains. PartsForMachines supplies oil coolers backed by the G&M Radiator range, the same manufacturing base the radiator family runs on, matched by application and dimensions. The formats follow the circuit. Air-cooled coolers, finned cores plumbed into the oil circuit and mounted in airflow, serve hydraulic systems, transmissions and engine oil across plant, agricultural and transport duties, while liquid-cooled and in-tank designs exchange against the engine's coolant. Matching runs by the machine and circuit: model and serial where the cooler is a catalogue fitment, and the measured route, core dimensions, connection threads and positions, mounting, photographed and confirmed via Ask Simon, where working machines and bespoke installations put coolers beyond catalogues, the territory the manufacturing capability behind the range exists for. The failure pattern is the radiator's plus pressure: fins blinded by the same dirt, seams and connections fatigued by vibration, and internal fouling where oil ran hot or contaminated, with the protective basics matching, cores kept clean, hoses and mounts renewed, and any oil-in-coolant or coolant-in-oil sign treated as urgent, since a failed liquid-cooled cooler cross-contaminates both circuits. The radiator family and HVAC rows sit alongside. For matching from measurements, contact the team via WhatsApp 07754288583.
