Remove warmup regulator tii

[Andy74tii]

I'm removing my warmup regulator to check for coolant sludge and so on. To me it appears that I do not have to remove the "top hat" at all, just undo the mounting bolts and the brackets, is that correct? I do not want to disturb the position of the washer or the orientation of the shaft if I don't have to, in order to remove it.

Thanks,

hmmmm, on second thought, it does appear that I do need to remove the top hat washer to remove. Is there any way around this?

I don't think so.

The position of the shaft doe not matter so you will not impact that.

Do you really need to remove the regulator though? Can you pull off the hoses and view with a mirror?

A possible check point for sludge build-up is in the coolant branch that bolts to the cylinder head.

Yeah, I am thinking I can get away without taking it off. I visually inspected the passages, they look pretty good, all things considered. I think I will leave on for now.

Thanks

Do check to see it is properly adjusted as well.

At 68F the piston that rises up on the regulator (the one with the slot in it) should be flush with the top of the regulator. If it is not, it can be adjusted - search for post from me on how-to.

Then check the gap at the enrichment screw.
