my 09 miniS just reached 100K.

on routine service, dealer just did oil change.

when i asked them after waterpump and turbo,
they just said don't do anything until they break.

On other cars i have, they ususally change waterpump and do timing
belt around 100K.
i know there is timing chain in our engine, so no change there,
but should i change waterpump now?

and what about the drive belt. Anohter mechanic told me the belt looks crack,
and i should replace it.
And he also recommended "tension adjustment". I have no idea what it is.
Should I do it? I havent done it yet.

Any recommendation that i should do at 100k mile?

thanks

 

Check the water pump and the thermostat together. Things to look for linked below.
The turbo should be fine unless there is an oil leak at the fittings feed and return lines, or the oil has been run low over time.

Main Water pump and thermostat:

Drive belt ( serpentine belt ) , if it look cracked change it.

Also check the engine for carbon build up on the intake valves.

Other then that its oil change , cabin filter, air filter for the simple things.

In many cars, the water pump is driven by the timing belt. Some failure modes of the pump can damage the belt or cause it to jump time. That often results in bent valves. That's the main reason they are both generally done together at specified intervals. (Often 90,000 miles.)

Our cars don't have timing belts, they have timing chains. And the chains do not run the water pump, so a failing pump should not cause the engine to jump time. So the pump isn't necessarily the "wear item" that it is in those other cars.

If the belt is cracking, replace it. I don't think I'd bother with the pump, though.

 

Since no one addressed this, I'll make mention of it... There is no "tension adjustment" on your MINI. It is an automatic tensioner. I don't know with certainty on the MINI, but I can tell you it is a fairly rare part to fail for tension issues... Maybe bearings, but I've never heard of one fail to tension the belt properly.

I think he was trying to get a few extra dollars from you.

+1 on the serpentine belt, though, as you don't want that to fail... It will leave you stranded.

 

Thanks! that is nice to know.

i will get the belt change.
He also mentioned oil leak on the turbo line.
do i have to change the turbo?

 

Turbo line leaking, get it repaired asap. The turbo should be fine..

 

Turbo oil lines here, don't nee to change the turbo.

Thanks all.
it starts to add up...

 

Normally the water pump starts leaking over time, as is the thermostat. Both are plastic housings that will develop cracks over time and leak. Also look at the bottom of the expansion tank, these can crack and leak over time.

The turbo oil line is a big job to replace, there is lots of stuff to remove to get to the fitting on the block. I hate to add to the list, but if you are replacing the turbo oil line, replace the seals on the oil cooler and oil filter housing. These will also leak over time.

So, turbo oil lines, oil filter housing seals, oil cooler seals, thermostat, water pump. Probably about $400 worth of stuff.

If the turbo oil line is leaking at the turbo housing, it is a potential fire hazard in extreme cases.

Sorry to rain on your parade...

Thanks for the info. I rather do it all at once.
Pay the shop once and get everything done.
I don't want to pay $300 for just one part, and go back and pay another $300
for the part in the same area, when i can get everything done togther
for a cheaper price.

 

Our 2008 Clubman S burned a valve at 107k. Dealer wanted to charge so much money that I was able to justify taking the time to do the work myself. Since I was going to have the head off and the front end in the service position I took the opportunity to change out nearly every rubber bit (hoses, lines, seals) I could find. I figure if we got 7 years the first go, I'll do all this and maybe get another 7 years.

With everything in place on the motor, access is woeful at best. You do need to remove this to get at that. Working around it usually ends up in body contortion and colorful language.

What I did learn from diving in was that some parts are very expensive, and then others you would think are pricey end up being $40. Do your research on prices.

Heater hoses are often forgotten. (I did, I really forgot to order them for this job.)
The aux water pump for the turbo is that $40 item. Comes already on a new bracket.
The main water pump, tension wheel, and all that is easy to do with the inner fender splash guard out. The plastic water pipe between the T-stat and w/p is delicate. Also, save the metal spring clip that holds the two together- it didn't come with the new water pipe, nor the new t-stat.

 

I'm at 116,722 miles, but my original (composite) water pump was replaced at around 69,079 with the redesigned MINI pump (aluminum body, composite impeller). It's been running for 47,673 miles, but I've already disassembled the engine to replace the clutch. I slapped in a Mishimoto silicone hose kit since I was in there, but that resulted in the discovery of a crumbly thermostat and coolant pipe. I'm on the fence about replacing the pump since it would be much easier at this stage, but MINI docked me for $216 for that pump, and it will probably last at least 30,000 more miles, if it lasts at least as long as the original plastic junk. If it lasts even longer, then it doesn't make much sense.
