Learn Spanish (Latin America): Tal vez la manguera del radiador está dañada.

Adverbs of doubt like tal vez can take either the indicative or the subjunctive depending on the speaker's level of certainty. Using the indicative (está) means the speaker feels this is a very likely possibility. If they had used the subjunctive (esté), it would imply more doubt or a weaker guess.

Why do we use está instead of es with dañada?

We use estar with past participles like dañada to describe the physical condition or state of an object resulting from an action. The hose is currently in a state of being broken, so we use estar. Using ser would describe an action taking place, not the resulting condition.

Why is it manguera del radiador instead of a direct translation like radiador manguera?

English often uses nouns as adjectives by placing them right before another noun, like radiator hose. Spanish generally does not do this. Instead, Spanish uses the preposition de to link them, literally saying the hose of the radiator (la manguera del radiador).

What happens if I move tal vez to the end of the sentence?
