It's normal for the level in the expansion tank to go up when the engine is hot. That's just normal expansion. As for your other issue, I would try replacing the thermostat. Hope this helps 🤞

Ah yes. That looks familiar 😂

I think you must do. I wouldn't have bought it otherwise. Get yourself the Haynes workshop manual. It's all in there.

Just stick the garden hose in for a minute if you can, with the drain screw open. Flush it until it runs our clear.

Hi Forncett, I'm pretty sure I didn't need any locking tools when I did mine. However it was a few years ago. I did have to by a tool to hold the crank pully while I un-did and did up the crank bolt. Must be some YouTube videos on the subject. Linx

Most kits come with the pullies and water pump. EG https://navigates.gates.com/emea/v/subaru/impreza/powergrip™-kit-%2B-waterpump-%2B-thermostat/gates/kp2th15612xs-3.html

I have a V40 too 😂. D4 engine. It needed a new EGR vvalve soon after I bought it but luckily done under warranty. Been good since 🤞. Looks like a new bottom support is about £55 from Import Car Spares.

No. It did pass a couple of mots before I sold it though. I believe Import Car Parts sell the support for welding in.

Brake booster pressure sensor

Maybe you don't have the correct adapter lead.

He did say it had been stolen ☹️

Wow! You're going to have to get codes ready for that. Is the engine light on?

You could also check to see if it's been SORN.

Oil and filter change every 5000 miles with fully synthetic oil and genuine Subaru oil filter.

Worn bearings usually make a humming sound.

When it's cooled down, is power normal?

I guess no fuel.

Could it just be the heatshield touching the disc when you brake hard?

Tighten the belt and change the fluid

Sounds like the pump is packing up. How long since the fluid was changed though?

It's probably a failing sensor. Have you checked for fault codes?

I'd go for a second hand one and just clean it up well. They don't often go wrong

I think you're looking at about 25mpg but reliable

I expect the pistons and seals need taking out and cleaning.

Welcome Spanner. I'm not sure where the oil leak is coming from. Looks like maybe turbo. You'll have to do a sniff test on the coolant and if OK, get it set up in a dyno.
