Water pump bolts -blue - and no RTE on pump gasket area ?

 

no rte, no threadlocker

 

Ok - Thx

 

If you are re-using cleaned, dry MEC bolts in cleaned,dry threads, Loctite 290 or 222 would be a good idea ?
The reason is that without the MEC coating & the correct fastener torque being so low, it may back out. At higher torque like there would be for steel bolt+steel casting ,no need perhaps.

I prefer using s/s studs+s/s nuts instead of bolts where possible for the M96 . Steel bolts in an expensive ,soft Aluminum casting is a potential problem in older cars where the original fastener has been in and out multiple times.The face of the w/p looks perfectly clean ,so that will help.YMEV. First ,do no harm....

 

Thanks Schnell - purchased new bolts and set the torque at 7.5 pounds - I did reuse old bolts on thermostat housing - I can back them out and put thread lock on them( went with LN thermostat for cooler temps) thx

 

Just ordered both 222/290 - put on new plugs and coils- new coils are thicker than original - in Raby spec book says torque on coils are 7.5 lb - worried it might break case since it's different design- your thoughts?

 

Follow the torque specs in the FSM or Jake Raby's Torque Spec book.
That is a hot location so maybe 294 is better there. You only need a little.
That situation is not trying to achieve some precise clamping force or stop fluid leaks. It is just to stop the coils backing off the spark plugs.
Careful not to muddle NM and ft-lbs !

 

I only use silicone and Thread sealant if I have a leaky water pump. I it is problematic I will silicone or glue the gasket to the pump and use pipe thread sealant on the bolts. If it never leaked around the gasket i do everything dry

 

The book says this is right - but it's a different thickness on the beru coil- old coils have a metal sleeve- not sure new ones have that.
