Coolant tube bolts - ZR-1 Net Registry Forums

LGAFF · 07-11-2010

Well I snapped off 7 of the 8....I thought the tube would slide off once the head either broke off or was drilled off....but its locked on good.

I shot some PB blaster in the bolt holes to see if that loosens them up.

Any ideas?

OEM gaskets leak coolant into the bolt & it gets rusty. In this instance, a plain gasket is better than the silicon bead on the OEM. Are you going back with stainless?

I like the OEM look, I will probably go with stock or allen head covered in anti-seize. Of course I forgot to order those gaskets.....although I might have a spare set.

Had to drill out one of the airhorn bolts also.

Do you have one of those hand held hammer type impact drivers. I don't recall what they are called, but motorcycle shops use them. If you can get use one of those, they're a big help getting out torx head bolts.

Lee I have a set if Jerrys gaskets if u need a set quick....

Thanks, I need to get a clutch too, might grab one from Paul....I will have to look I might have a set from the 92 I did not remove the bolts....but might have given that set away to someone.

I am also seeing the secondaries hanging up on one side might explain my 310rwhp a year or so ago....

Wonder if that isn't Han's problem?
I used stainless Allen head bolts with anti-seize.

Wow these things are no budging....are these threaded the whole way through or just in the IH housing....I cannot image its threaed in the tube

No threads in the coolant outlet tube, only in the inj hsng. The bolts, for some unknown reason, are threaded all the way to the bolt head. Lots of friction surface for rust. Heat & soft mallet.
