I have a 2005 Boxster S with 17K miles. I purchased the car last April with 13,500 miles.

At around 14K the water pump went out. (bearing sounds and coolant loss)

I had the pump replaced under an aftermarket warranty at my independent Porsche shop. (This shop is highy qualified and very active within the PCA)

Since this time I have been through 4 water pumps. After they replace the pump I will get a small drip out the weep hole and have to add a very small amount of coolant to keep the fill tank in the middle.

This is nothing major - I am talking about 1 bottle of water's worth over the course of a month.

The water pump is OEM and made by Lasco.

Does anybody know of any other pump that is more dependable than the OEM?

Any thoughts or suggestions?

 

I have 175,000 miles on my 99 2.5 I replaced my water pump at 120k miles a few years ago with an AutoZone sourced part.

I am of the opinion that there is something else wrong than the waterpump. 4 is just alot of pumps to fail. Did you change the gasket everytime?

 

Hmm...A cursory search of the regular suppliers for parts lists only a Laso, but they are listed as an OEM supplier.If they kept weeping around the gasket, you could suspect poor installation, but it is a pretty straightforward job, and coolant out of the weep hole should only be an internal failure of the water pump.(Unless they use a hammer to install it....)I can also say that we installed one of the Lasos is my car at least 20k ago with no issues.4 bad water pumps is highly unlikely, but a Porsche shop messing it up 4 times in a row??Very perplexing...-Brad
