I am looking to purchase a Pierburg water pump as an upgrade to the supercharger cooling system. Does anyone have any photos of how they mounted it? Also are you able to use the existing hoses without modifications? Any feedback or suggestions is greatly appreciated.
Hi @JgaXkr . Firstly despite your username I'm assuming you are asking about fitting the CWA150 to a F-Type I carried this mod out last year, but unfortunately did not take any pictures of the install. However, from memory It wasn't that difficult. With the aid of some pictures, I'll walk you through it.
Firstly, pump comparison
The Pierburg is a fair bit larger than the OE pump, but it will fit in roughly the same position as the original.
You will need to source a Kostal Connector Kit compatible with the CWA150 as the stock connector will not fit. See --> Pierburg CWA150 Connector Kit or similar.
Pump/pipework location - RH side of radiator (facing forward)
You will have to remove the front bumper to gain access to the Intercooler Water Pump, See -->
. There is no need to move/reposition any hoses, as the Pierburg uses the same inlet/outlet arrangement of the OE pump. A pair of hosepipe clamp pliers will prove useful for removing/fitted the relevant coolant hoses. Most of the OE pump weight is borne by the inlet/outlet hoses, with a 'steady' bracket to prevent vibration.
Undo the bracket bolt and remove the steady bracket. Disconnect the inlet and outlet hoses (I removed the undertray and drained the coolant by disconnecting the pump inlet). Unplug the OE 3 pin connector, remove the OE pump.
Snip the OE plug and fit the Pierburg Kostel connector to the OE harness. I only fitted the +12V and ground wires and isolated the PWM control wire, as the F Type ECU cannot supply sufficient current to drive the Pierburg in-pump controller. This will result in the pump running 100% duty cycle, rather than running idle while the engine warms up. Basically the Pierburg will run whenever the ignition is switched on. You can pull the fuse in the engine bay fuse box to stop the pump if you need to work on the car with ignition on. Leaving the PWM control wire disconnected will also log a DTC in the ECU (P023a), but will not trigger a MIL on the driver display (or limp mode). You cannot clear the code, but it will not affect normal engine operation. I cant remember the colour coding of the OE harness, but easy enough to check with a multimeter/test lamp. The Pierburg pinouts are:
Mount the Pierburg pump in the same location as the OE pump. Some cutting of the NVH suppressing foam will be required to allow fitment. I used an aluminium 'Z' bracket to bridge the original bracket mounting point and secured the Pierburg using one of the pump body joint screws. You could also use a large Jubilee clip to steady the Pierburg similar to the original OE install. Refit the inlet/outlet hoses, then refill the coolant system, being sure to follow the Workshop procedure (unbolting/raising header tank and bleeding from upper 'Y' pipe, see workshop manual available on the forum).
Once the coolant system has been filled and bled, check for leaks around the pump. If all OK, refit bumper (and possibly undertray if also removed).
Finally the Pierburg runs at a quoted max 15 amps. The stock pump is served by a 10 amp fuse, so to avoid (otherwise unknown) pump failure due to high current load, replace the stock 10 amp fuse with a 15 amp.
I think that's all the relevant points (albeit it from 1 year old memory ). Hope this helps with your upgrade. Let me know if you have any questions

I purchased the pump from VAP over the summer. My question is weather there is an actual mounting bracket that can be used.
No mounting bracket that comes with it. You do have to make some space where the stock pump is currently located, to fit this into the area. I have seen solutions like custom made brackets after some slight modifications to the surrounding area, to fit the larger size pump. We are working on a number of FAQ/installation tips and tricks across all our products at the moment and uploading directly to their respective product pages. Once we get the Pierburg page updated, I will make a note to send you a link. Did you receive our wiring harness when you purchase the pump from us? PM me your order number if you did not and have not yet installed.
