Changing the radiator or removing it for repair at the local radiator repair shop is a big operation on the pusher school bus. The charge air cooler, oil cooler and radiator are sandwiched on top of each other making it hard to get the radiator out of the chassis.
The objective in this video is to show you a short cut that all mechanics love to do saving time and some frustration.
The way we do it is to support the upper components and loosen off the radiator mounts. The frame supports have to be loosened as well to allow space so the the rad core can be removed freely.
The cooling fan which is a Parker system is braced to the main frame around the radiator so it needs to be chained up out of the way.
In most cases if the radiator is original and has a leak the chances of repairing it is remote I'm sorry to report.
This rad core is over 12 years old and has gone through a lot of weather and road debris kicking up into and around the core area on a daily basis. There are cores out there but we had to get one from Thomas buses.
I hope this video helps you bus mechanics out there.
I would appreciate it if you shared or commented on this post. It's great to get some feedback from others who have had similar problems and found a faster way to get them done. Time is a precious commodity in a fleet garage and with that said I'll continue to share videos on repairs that will help out fellow mechanics.
