Charge Cooler coolant overflow
Posted 22 January 2012 - 03:54 PM
I took the SE for a run down the road and upon my return noticed that the coolant from the CC header tank was flowing quite well from the overflow pipe at the top. I have not topped up the coolant for about 6 months and; in fact thinking back, it leaked a little the last time I drove her a couple of weeks back. The CC itself is not cool but only midly warm and seeing as the car has been a non runner for around 6 years before I owned her; I can only assume that at some point soon I will need to replace the pump; however did not think that this coolant issue would be simptomatic of a corroded pump.
What is the most likely cause of this overflow?
I would appreciate any input.

Quick update: checked the CC header tank and that was completely dry......last time I checked it (around 2 weeks ago when I last ran her) it was completely full!

Get an electric pump, you're losing out on 40+ bhp right now!

the impellor on mine looked in as good condition as the new one but on inspection the rubber had come away from the brass center so any pressure on it and only the center rotated rendering it usless, mine went dry due to the front pipes being caught by the tyre on full lock, looks like the pipes had been bent forward causing the rubbing.

I have now replaced the CC Pump on the SE, flushed through the system but I am still getting a lot of coolant loss from the CC header tank (smaller of the two) through the over flow pipe. Would you expect this as the system balances itself out or is there still an issue here? I will connect a hose to the CC inlet and I would imagine that this would then overflow the header tank if there are no blockages. When I ran the system up after replacing the pump; I did it in accordance with the manual by just filling the header tank initially and then topping up as it went down. Do I need to bleed another way? Your advise and thoughts would be appreciated.

Only just picked up your post!
With regards to the CC; I have just realised that I had merged the two systems..... there is a very similar hose which leads to the T piece behind the turbo. I had swapped the CC outlet hose with that. Only realised when I purged that hose with a hose pipe and notice it overflowing the main header tank.....Doh!!!!!!!!!!
Still cannot get the CC down to a nice temperature though...... Any thoughts?

That would be great if not to much hassle?
I will be at the unit on Saturday early afternoon.

Can anyone confirm that the bleed nut on the chargecooler unscrews anti clockwise?
If so I could be doing a bit of swearing tomorrow its stuck solid,ive got the cc off and
left it soaking in Rostoff ice.......could be a bugger.
