Here’s some pics of a bunch of Mesabi radiator tubes we're in the process of reconditioning. Some of the Mesabi radiators we get in for rebuilding have aluminum tubes while some of them have copper tubes. We prefer, and highly recommend, the copper tubes as they are much more robust than their aluminum counterparts. Aluminum [...]

Here’s some pics of a Komatsu 930E-5 haul truck radiator we picked up for repair & remanufacturing. The radiator is a Mesabi unit with all aluminum tubes. We are removing all the tubes for cleaning & reconditioning as well as replacing all the upper & lower rubber grommet seals. There are some damaged tubes that [...]

Here’s some pics of a Caterpillar D10T2 dozer radiator we had in for a complete rebuild overhaul. The radiator is a Modine CGT, copper grommeted tube, unit which had seen better days. There were fifty tubes that were worn very thin from debris being thrown at them by the fan. All the other individual copper [...]

Here’s some pics of a delivery we made to a couple of our mining customers. The yellow radiator is for a Caterpillar 793C haul truck. The radiator we brought in was a folded core radiator & our customer requested us to change it to a Mesabi radiator. So this radiator is a new unit with [...]

Here’s some pics of an aluminum radiator we had in for a Grove RT600E crane that was leaking in the tubes of the core from internal plugging, or fouling. The build-up inside the tubes allowed corrosion to take place which ate the tubes up internally causing leaks in the tubes of the core. We cut [...]

Here’s some pics of a radiator & intercooler stack cooling package we finished up for one of our mining customers. The longer unit on the backside is the radiator. The shorter unit on the front, or engine side, with the long curved upper connections is the CAC (charge air cooler). Both the radiator & the [...]

Here’s some pics of a copper and brass four row radiator we had in for a rod and repair. Both the inlet & outlet tanks were removed. The tubes were rodded out to clear them internally of all fouling & blockage. We then ran both headers which involves melting all the solder off of the [...]

Here’s some before & after pics of an aluminum oil cooler we had in for cleaning & repairing. This cooler is for the compressor on an Epiroc D-65 drill rig. We first steam cleaned the cooler inside & out. It then gets soaked, or boiled, in our ultrasonic. After it's completely clean inside & out [...]

Here's some late night pics of a 793F Cat radiator we’re in the middle of rebuilding. The radiator is a Mesabi with a little under eight hundred individual copper tubes. Once the radiator rebuild is complete & it passes the pressure test we will start installing all the external cooling system components. When we're all [...]
