Wanted to Borrow- Vacuum Filler for E30 Coolant

[nick496 268]

Hey Guys

I'm wanting to borrow a vacuum filler to get all the air bubbles out of my E30.

I've spent about a tank worth of gas, with it sitting idle in the driveway, and slowing getting bubbles out.

But it's done my head in, so I'm after a quick and easy solution

(Yes, the front is more elevated, heat on, fan on max)

So if anyone has one to borrow around Hamilton that would be great.

Cheers

did you take the screw out of the thermostat?

an e30 is easy to bleed whether M20 or M40 engine, if air is still coming into the system there will be a leak somewhere maybe small head gasket failure or pinhole in a hose etc

I haven't taken the bleed screw completely out of the thermostat housing.

I've been cranking it ever so slightly until I see bubbles in the liquid flowing out.

I can't see any leaks from the top down, and there doesn't appear to be radiator fluid elsewhere, but good idea and will have to test that, so I guess a pressure test will be in order.

Thought I'd update this with what fixed the issue:

Took it into my mechanic, told them it was overheating when idling. (Temperature gauge sitting a good few mm to the right of the centre)

They ran a pressure test, replaced a few hose clamps.

Ran it again, no issues with leaks.

Still showing overheating temp when idling, so that isn't the issue.

They got the temp gun on it. Showed normal temperature.

Turns out the fix was to tighten the ground screw on the cluster.

-I had heard of this ground screw, but had dismissed it due to my temp gauge not flickering. (Not relevant to reading high) But I was wrong.

Temps now showing normal.

Where abouts is the ground screw located, do you need to remove the whole cluster ?

You'll have to pull out the whole cluster.

It's the copper nut + washer that sits behind the gauge.
