Hi Guys,

I have another issue with my S2000

After piecing my engine bay back together after a small oil filter fire, i changed the coolant, only i noticed there was rather little coolant left.

I filled the rad back up got it bleed, when i noticed steam coming off the radiator once engine was up to temperature, so looked like i had a radiator leak

So i have now changed the radiator, so no leaks here, got it bleed, so thought things were good. Only the other day i noticed the heaters had lost their heat.

So checked the coolant, no obvious leaks, but obviously air in the system.

No matter what i do i can't get the air to stay out! i have read how to bleed, but the air just comes back


A few things noticeable:

1: there is a rattle coming from around the middle of the engine, near the water pump? Rattle gets louder with revs.

2. There is basically no flow at idle? if i open the bleed valve at idle nothing comes out? same with the rad cap? Unless i add a good few revs there does not seem to be any water flow?

3. it occasionally sounds like I've got a supercharger, when i start her up, and especially when i shut her down, i get this whoosh sound? Infact almost like a vacuum cleaner.

I would imagine its still on the original pump, so would be 13 years/90K miles old.

Does this sound like the water pump? could this cause me bleeding issues?

Cheers

 

Did any of water hoses on the oil cooler damaged when you had the fire?
