I love that Aussie car product you can buy called ‘Start Ya Bastard’ for cars that won’t start when they should, but today I had the opposite problem – the Cruiser wouldn’t shut down… So if you also happen to have an HJ61 Landcruiser and you can’t get it to stop then this may be the post you are looking for.
I was a little confused because I took it in yesterday for a new radiator and the problem only occurred after that. I drove it home, turned it off, took the key out and she just kept running. It began by just running on for a few seconds before shutting down so fortunately I was aware of it and didn’t get stuck out and about with a car that I couldn’t stop. But tonight it just decided to keep running and running and running…
I discovered how to shut it down manually by activating the diaphragm – just push the rod towards the front the of the car (see the arrow on the diagram) and it stops. But this is supposed to be activated by a vacuum and clearly that wasn’t happening. I could do it mechanically but it wasn’t working as it should have been – and all hoses were intact…
I tracked the hose back to the device that has the red square around it but then got stuck. I didn’t know what it was and didn’t want to bugger something up.
But don’t you love google and forums?! When my dad wanted to teach me about cars at 17 I just wanted to go surfing, so I didn’t take anything in and now I am playing catch up. But fortunately a google search revealed others had encountered this problem too. I began reading at 8 o’clock and at 9 I was out there in the shed with a spotlight trying to get it back up and running.
So the vacuum switch valve (vsv) is the one in the square that activates the vacuum that shuts the car down. It is held on by one small 12ml bolt. I pulled it off cleaned it and blew it out, put it back on and all worked well in several tests. I am guessing some crap in the valve may have been the issue.
The forums showed that these valves are expensive – about $170 to buy from Toyota – if you can get them… but if you can’t you can get the same valve on Corollas manufactured in the early 80s and they are a dime a dozen around wreckers.
So there you have it. She stops now which is good because come Friday next week we are off to Karajini for a week and out of internet range.
Thanks to those who took the time to put it on the forums – just thought I’d return the favour to anyone searching for this problem.
If you need to access a manual for the 12HT then Tim has kindly uploaded one here and it is section EM34 you need to refer to.
