What is a radiator spindle?

How to remove a broken bolt from a thermostat housing?

Insert a shop rag into the opening of the thermostat housing to prevent metal shavings from entering the engine. Index the center of the broken bolt, using a deadblow hammer and punch. Ensure that you keep the punch centered and do not allow it to slip.

What to do if your radiator hose breaks off?

Hi, similar issues show up on a lot of these older Mercedes. If this piece breaks off you can try to fix it with some epoxy. But it is not a separate part. If you don’t like the idea of fixing it with epoxy, or that does not hold up, you will have to replace the radiator.

What happens if you remove top of radiator?

How do you remove Union NUT from Radiator?
