Small Coolant Leak.

[TheTopGun]

Hey, I've got a slow coolant leak from this hose that goes into the thermostat housing. How exactly does this seal ? It seems weird that they don't just use a normal outlet and hose clamp.

It has a oring sealing it into the housing with the tab/10mm bolt holding it in place.

Use a small amount of vasso on the new oring if that one has perished when installing.

Ahk awesome, sounds pretty straight forward. Hope its just the o-ring and the hose isn't perished aswell.

Don't use vasoline. Use silicon grease or or coolant

The hose is steel

That's the pipe that goes into the back of the water pump.

I've replaced water pumps twice on BF Falcons. Absolutely hate it, and it's taken me hours each time.

However, I've done it the hard way... ie without removing the power steering pump. There are holes in the power steering pump pulley - you poke a socket through those holes to undo the bolts holding the power steering pump in place. Remove the power steering pump and the job becomes a whole lot easier.

There is an o-ring that goes on the end of that pipe, where it goes into the water pump. Because the pipe is metal and won't move, you have to remove the water pump just to get to that &^%$# o-ring. I bought a pulley-puller gadget to use the next time I try that job, but haven't used it yet (ie to remove the pulley on the front of the water pump).

Don't forget to get a new gasket for the water pump. You'll have a ton of fun peeling off the old gasket.

Next time I do it I'll probably get carried away and remove the radiator and front bumper just so that I can get better access.

Evil, nasty job.

Well you just put me off that job PHIL.

Mines had a wee weep since I bought the car but no where near as bad as the OPs.

HANG ON...... Why do you need to remove the water pump?

Maybe the thermostat housing but the water pump is on the other side (see pic)

Mines a BA Typhoon, are they different too the BF?

Well sh*t, look at that... I got it wrong. Had to happen some day. I thought that the first photo was of the pipe that goes into the back of the water pump. It's an almost identical setup there. The second photo shows the area better.

Dunno if the pipe on that side moves - it doesn't move on the water pump side, hence the water pump has to come out just to replace that ^%$# o-ring in the back of the water pump.

Pretty sure that the BA setup will be the same as the BF.

removing waterpump ?! craaap scared me for a minute haha. Yeh this is thermostat housing, I was hoping to just loosen that tab pull hose out and replace o-ring but I guess it might not be that simple :/

Just replaced mine.

Undo tab and turbo feed if the car is turbo and pull the pipe back gently.

There was enough movement in mine to get a new o ring on.

Mine didn't have an o ring at all

Did you check to see if the old oring stayed behind in the thermostat housing?
