Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

While I take headers off and get them ceramic coating new plugs -coil packs, I figured I should replace water pump - any help appreciated

POST 2Original post

You want a plastic composite impeller. A OE Porsche pump in a Porsche box. Smart to change before failure.

POST 3 / ORIGINAL POSTEROriginal post

For sure - while I have everything out of the way might as well get that done

POST 4Original post

I would suggest replacing the thermostat as well and take a look at the belt, might need replacing depending on wear.

POST 5Original post

how often should the water pump be replaced? My car has 110K and I have no record of it being changed...

POST 6Original post

People like Flat 6 and L&N suggest every 4 years.

Depending on your budget and priorities, consider also : Low temp T-stat idler pulley bearings Serp Belt Check p/s reservoir for leakage at the neck. If the coil packs are not cracked/no misfire codes, why change them? Plug tubes and seals ? Be careful with header bolts ! Maybe best to leave them alone if they stubborn. Snaping header bolts is a problem best avoided.

POST 8 / ORIGINAL POSTEROriginal post

I have snapped one bolt on header - all others came out after I ran the engine- I have it drilled out 90 % - can you tell me which parts to order ? All spark tubes look good really don't want to pull those / should I ? -

POST 9 / ORIGINAL POSTEROriginal post

Lo temp thermostat- 180? Degree - I noticed different mfg - do I need new housing? Thanks

POST 11Original post

You are welcome. The best single,easy source to look for parts is probably Pelican. Speaking of priorities and budget: everything stops until you deal with the broken header bolt.Timsert? There are kits to replace the bolts with s/s studs.A far better solution imho. You can find generic kits on EBay cheaply but you must do all the measurements yourself to get the correct kit.

POST 12Original post

Lo temp is 160. OE is 187. You can change just the thermostat.

POST 13 / ORIGINAL POSTEROriginal post

How the eff do you get the water pump out if it only back off with impeller still partially in block? Also with the finess of a ninja got the remnants of header bolt out and tapped with 8x125 bolt screws in ( slight slop) at beginning better towards bottom

POST 14 / ORIGINAL POSTEROriginal post

Most sites only have 180 - where do I find a 160 Thanks DBjoe

POST 16 / ORIGINAL POSTEROriginal post

My water pump won't back out with support plate- any ideas?

POST 18Original post

Follow the specific instructions. Support the engine and loosen the rear engine support bracket. You have to back it all the way back towards the rear of the car.

POST 19 / ORIGINAL POSTEROriginal post

Support plate 3 bolts-Backed off just enough to pull out pump - got it - it is plastic impeller will order porsche pump thru Renn sponsors

POST 21Original post

Here is a very good video on 996 water pump replacement, but don't use silicone as he does. The metal gasket doesn't require any sealant. https://www.youtube.com/watch?v=h0L0klF8lVo

if you have an air compressor get a uview coolant replacement tool on Amazon, works great and is super easy.

If you have an air compressor, I had a write up to drain all the coolant. Search for 3 step simple coolant drain.

POST 26 / ORIGINAL POSTEROriginal post

Will do - going to replace most of rubber hoses on motor, seems like scale from green antifreeze Near housing- i ordered LN thermostat for hopefully better temps

POST 27Original post

If you want the same thing only cheaper, go to warehouse33auto.com. Same exact parts, only about 7 or 8 % cheaper. Then, take another 10% off by using promo code RENNLIST. Jason's shipping charges are also often cheaper than competitors. I like Pelican also, but warehouse33auto.com has great service and always costs less. The owner of warehouse33auto.com is a Rennlister and a 996 owner. http://www.warehouse33auto.com/parts...901/4/0/2200/0
