1980 International S-1700 school bus engine fires up!

The engine started up and ran very smoothly on a small amount of gasoline poured into the carburetor. Now I need to remove the transmission, clutch and flywheel to repair the coolant leak. I only let it run a few seconds as it didn't have much coolant in it. The popping sound heard when the engine is running came from the air compressor which was disconnected from the brake system for some reason.

just wondered if the head gasket was ok.

[retrochad]

Yes I think it is as there was no water in the oil. I do have a compression gauge so I may double check...the previous owners were trying to run a compression test probably because they thought the water leak was due to a head gasket but I am thinking it's a freeze plug/

An international with a 4bl carb. Mostly I've seen them with 2bl carbs. Would there usually be a cap on the radiator? Or does this have a remote expansion tank?

[retrochad]

I'm thinking it would have a remote expansion tank and that is where the radiator cap would be...I saw this on an IH diesel bus. Not sure why a previous owner would have removed it.

Good luck with this bus! I hope all goes well with the removal of the transmission.

the best thing support the transmission/gear box. the unbolt the bell housing from the block with a manual transmission remove the clutch fork leave in a gear easely reinstall the transmission fix the leak.
