turbo coolant pump

[valjo]

i think my tcp pump is death. when i turned ignition key on (not start engine), i cant hear any sound from tcp and when i put hand on it and my friend turned ignition on i cant fell any noise from tcp. what could be cause of it? Is possible i have problems with any sensors or wirings? Can i cause any damage on my car ? (it is very cold in my countr now)

There´s some good information about the after run pump on s2central.net and also in this thread .

If you have an immobiliser in your car make sure it's not activated when turning on the ignition. It could mess with the signal to the TCP-relay.

This is sommat i havn't yet check but really should do! Could any one tell me where it is? And don't say in the engine bay either!!

In the engine bay

More precisely bolted to the lh side engine to body mount and has hoses connected to it from the rad and from an external coolant pipe.

Valjo: No, you really can't harm your engine if you let it idle for a while before turning it off. Cold is no problem, just better.

All turbo cars should get a while of idling after hard driving even if it has an after run pump.

I found out that volvo use the bosch turbo coolant pumps identical to ours and that they are about 45 quid all in from volvo, might be worth investigating.

thanks for all infos about tcp.
i want to ask you if it is possible i have some gizmos in electronic system? sometimes when i started my car my radiator fan at once start working at speed two. (my car has AC) I wonder if it is wrong? and if it is connected to problems with TCP somehow:confused:

Grega,

If your rad fans comes on when you start the car, you probably had the AC turned on then!! as soon as you turn on the Ac, the rad fan comes on straight away!! try it...

martyn it wont work like you decribe it. Nomether if i have AC (i mean clima it has symbol like crystal) on or off radiator fan works when i strat engine. But if i shut down AC completly radator fun dont run.

Any new ideas abou that m8es??!
