This thermostat for Caterpillar is supplied as a cost-effective alternative to the genuine part, manufactured to OEM dimensional specification. It drops into the existing mounting position and works with the original hardware.<\/p>\n
OEM and interchange reference: 497-3990 | 4973990<\/strong><\/p>\n Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us \u2014 we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.<\/p>\n E333<\/p>\n Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.<\/p>\n On Caterpillar machines the thermostat has to reject the full engine heat load while sitting behind a radiator that is often already partly blocked with dust. We supply to OEM core specification and check fin integrity and joint pressure before shipping, because a pinhole leak here shows up as coolant loss under load, not as a puddle on the floor.<\/p>\n Order quantity is flexible \u2014 one piece for a machine that is down, or a full container for your stock. Goods are packed part by part with clear labelling for your stores, and we provide inspection photos plus measured dimensions before the balance payment.
