Tech Question

[4ROLLN]

Ok so i was going to change the radiator hose on my altezza to a steel one pulled half of it off, the engine side and about 1 litre of coolant came out which i caught with a icecream container right! so anyways i put the pipe back on, car had flat battery so jump started it, let it warm up, then when putting it back in shed i reved it about 3000 - 4000 and could hear water quite loud flowing, sounded like in dash which is impossible, so turned it off, then had to put it back in shed so turned it on and drove it into shed.

After thinking about it I came to 2 conclusions:

1. Must be the water filling the pipes up again and recurculating!

2. By taking hte pipe off air got into the pipes.

Well I hope its just 1. but it shore makes a funny sound!!!!

ideas guys?

did u refil your radiator with more coolant after u let some of it out? (That liter of so which u caught with your ice cream container)

Yeah, I'd say you let air bubbles into the pipes and they are circulating through the heater. They should clear out over a few days, although I don't know if there is an air bleed nut somewhere up high on the system. I'm afraid I haven't looked for that.

I ended up putiing it back in but the water was still halve full when after i did it and after putting it back in it was difinately full full!!!!

I cant see how it could be anything else, you dont think it could harm the engine "greeneyes"?

hopefully it just goes away cause it dont sound cool!!!!

It may look full after you filled it, but as soon as it warms up the thermostat will open and any air bubbles underneath it all rise up. This will make the water level go down and it will magically appear low again. So check it tomorrow morning and make sure it has stayed full.

Small bubbles may get trapped in the top of a curve in the heater, so the water can flow passed but the trapped bubble gurgles for a while. Shouldn't worry the engine but may take a few days or week to clear them out.

Keith is correct - check after a few days. I changed my rad hose for a Greddy aluminium one, but my pipe has a bleed valve on it...

Monitor it over the next few days and let us know how you get on...
