Liquid slushing sound when cold + throttle

Post by wenguin »

Yesterday I had my throttle body off to give it a quick clean and put a new gasket on. I disconnected everything from it expect the larger hose on the right hand side (if you're looking into the butterfly hole).

I disconnected the hose at the bottom (the thin one) and a load of liquid spurted out - it sort of smelt like petrol - is it petrol, or coolant?

Anyway, my problem:

- This morning I drove the car and noticed that when I revved the car, there was a loud water/slushing sound - it sounded like it was coming from under the dash passenger side, or underneath the car.

- I got to where I was going and tried revving again and it was still there

- 5 minutes later I came out, started it up and tried again - no slushing

- By the time I got home I tried again, no slushing

So it appears to only happen from cold.

Any ideas what it is? Was the hose on the bottom a coolant hose, and when some spurted out it has created an air gap? Or will it just need topped up?

Let me know if you need more details!

Thanks!

update: discovered a leak in my radiator - the test was putting my face down to look where the little bit of smoke/mist was coming from and getting a face full of coolant!

Will order new radiator tonight then - will I need to flush the coolant system while I'm at it? Just read another thread here saying the coolant itself is quite expensive #-o #-o

If you buy toyota's yes but the workshop manual only states that you should use a good brand of "Ethylene-glycol base coolant" so it doesn't have to cost the earth.

I use this, it meets the requirements and doesn't cost much

Cheers mate! Is there anything special in the Toyota stuff I'd be missing out on? Will probably be taking the car to a few track days this year if that makes any difference :eye:

Not to my knowledge both have a life cycle of 3 years, used in mixed metal engines and are a Ethylene-glycol based coolant

Replaced my radiator today - there's supposed to be two fans on an N/A rev3 radiator, right?

There was only one on mine, so I'll need to grab a second one.

Anyone happen to know the size of bolt/washer that is used to fix the fan to the radiator?
