Rb25Det Block Coolant Drain Bolt

[zoomzoom]

In an unpleasant face-full-of-coolant fail, I appear to have misplaced the coolant drain bolt, just under one of the oil lines going to the turbo. Can anyone confirm what the thread and pitch is? I tried a 12mm x 1.5 pitch thread, and I think the width is correct but the pitch isnt.

Is this on an R33 GTST? Unfortunately I can't give you the details you are after...but...can you tell me how you got to this little sucker - for years I have been draining the radiator only...thanks!

Yeah sorry i cant help you with it either, but as far as i could tell it was a tapered bolt I think. Go to a wrecker and grab one out of an rb30 or something similar

And Peter, if your car doesnt have ABS, it was possible for me to get it from the top with an extension and a knuckle thingy. Its on the rear of the block, just above the turbo water return i think!

I meant to take a picture when i did it as NOONE seems to have ever done it clearly haha, but alas, i forgot

Thanks mate I don't have ABS so I'll check out the bolt this weekend and see if I can locate it!

Sorry about the late response as I dont get any email updates, though it looks like you have it sorted.

I used a socket > universal joint > 25cm extension beam > breaker bar

Its a pain to get to, but once you get the bolt to move, then just use a smaller socket wrench.

Also for anyones benefit, when you put it back in, remember to use a thread sealant. I used a loctite? branded one designed for sealing water, which sets in an anaerobic environment or by heat.

I should also say that even with the coolant that sprayed everywhere, I got most of the workshop manual specified quantity of coolant out. Draining the radiator by itself doesnt replace much of the coolant.

Yeah just dropping the radiator only gets rid of half the coolant if that. After draining mine and pulling the waterpump off i flooded the garage floor with 4+ litres of green shit. lol

You shouldnt really need any thread tape or sealant on that bolt as it is tapered. So if you dont have any i wouldnt waste your money. But in saying that, if it leaks dont yell at me I didnt use it on mine when i took it out.
