engine and drivetrain Torque Values For Water Pump

[schoir]

Are there any torque values published for the 4 10mm head bolts and the 3 13mm head bolts for installing the water pump on a 2002?

 

Regards, Maurice.

check the current thread on sub frame torque for link to torque spec sheet.

check the current thread on sub frame torque for link to torque spec sheet.

I could not find the thread looking at a list of current threads or with "sub frame torque" search.

 

Do you have a link?

According to Haynes water pump securing bolts @ 20 ft/lb

"torque specs subframe" yesterday. I can't copy link.

Thanks John in VA. Those bolts have different torque settings.

FYI, original torque specs document was missing torque values for water pump securing bolts and front subframe (crossmember) to car chassis. The values that I posted for the two parts in last couple of days were taken out of Haynes (pages 38 & 171)

I sent PM to williamggruff, who is author of this document in Excel format to kindly add torque values for above two parts.

For reference only:

Thanks.

I always think of the German torque specification "guttentite" when I'm searching for the right #.    

[Hans]

My error. I didn't actually look for water pump or else I would have posted.  anyway, I see 20 ftlb, but I thought there were two different sizes of bolt on the pump. If not, then have at it.

I reviewed the original document again and noticed another item missing is timing cover bolts. It seems there two different size bolts used on timing cover. Haynes manual (page 15) call for the small bolts setting to 6ft/lb and and large ones to 18ft/lb

I changed a water pump in 1999 and torqued the bolts using the "guttentite" method, and they stayed guttentite for 88K miles.  Never really had a problem with that method.

 

Cheers,

Thanks for the reference materials and the links.  Quite a lot of work went into that spreadsheet and it will prove very useful, over and over.

 

Although the Haynes manual shows 20 lb/ft for the water pump bolts (page 38), there are four small bolts and three large bolts securing the water pump.

 

Since the Haynes manual also shows 6 lb/ft for small timing cover bolts and 18 lb/ft for large timing cover bolts (page 15), I'm going to go with the 6 lb/ft spec for the four small water pump bolts and 18-20 lb/ft for the three large water pump bolts.

 

I like the guttentite method too, but I like general guidance because of the sensitive nature of aluminum threads.

 

Regards, Maurice.

My recollection was two different sizes. Which means different values. Can't recall what I found last time, but 6 and 20 sounds reasonable.

The M6 bolts should be 9-11nm (6.5-8 ft. lbs) and the M8 bolts should be 23-27nm (16.5-19.5 ft. lbs)
