This might be a dumb question so sorry haha, as I haven’t done it before but I am Replacing my single turbo on the FD soon and I was wondering if I have to drain coolant and oil? Or are there any other crucial steps?

thank you

No, you don't have to.

Oil is in the pan with the car off, so it's there, no need to drain.

Coolant you can lose some, you can sometimes cap or clamp the hoses to prevent losing all the coolant.

But it can be a good excuse to do both.

Draining out the coolant before removing the turbo will make the job less messy.

Also as Dale said, a new turbo is a good excuse to change the oil too - do you really want to fire up your brand new turbo for the 1st time with dirty used oil? And while we're on that subject, it's recommended that before you fire up the engine for the 1st time after installing the new turbo, that you prime it with oil pressure first.... To do that, you'll need to disable fuel/spark first (so the engine won't start), and then crank over the engine for at least 30 seconds to build oil pressure up & get oil flowing thru the turbo's bearings. Then re-enable fuel/spark and start it up.

all under the assumption his current single has water lines. considering he asked, logic would dictate he does but if he doesn't then obviously there's no need to drain the coolant. pete is correct about priming it first. it helps to leave the oil return off so you know when you have a steady stream coming out. no need to guess if you primed it enough or not.
