[Healeys] Clip for Capillary AHB5397

Wed Nov 6 09:27:10 MST 2019

If equipped with a heater, the Mk I (29D engines) used return pipe that sat closer to the manifolds.  The temperature capillary tube is not fastened to mounting brackets for this lower pipe as it is with the higher pipe on later cars (starting with 29E engines).  Rather, the tube was attached using the brackets in the attachment Harold sent, clipped on the inboard side, toward the rocker cover.  I believe the clips in the photo below were used for both capillary tube mounting styles.

I think these may be the clips that you are referring to BHA4081 but I'm not sure that they went back to the MkI

The "clip" shown in the photo is something you can fab up yourself. The lower hole is the size of the manifold stud.  The top hole is where the real clip, the clip that actually holds the capillary tube, fits into.  It is smaller than the stud hole. Can't tell you precisely here, but the size is critical to hold the small clip securely.  The clip I am referring to is very similar to the clip that holds the slave cylinder clutch hydraulic line to the right side footwell, in the vertical position.

Hello,

My car was missing the clips to support the water temperature gauge capillary pipe part number AHB5397. It looks like the design was changed sometime during the Mk II production or later. My car is a Mk I. The part I am looking for is No. 25 on the attached PDF. It is not available from the "usual suspects" on either sides of the pond.

Does anyone know a source? I can make the part but would like to have a sketch to work from. I am fine with used parts in reasonable shape as well.

Any assistance is appreciated.

PS - A significant contributor to over heating when slowing down after a long drive is the lower water flow generated by the water pump. Lets face it the the AH cooling system is marginal and there is no magic solution. Best practise says use a water and antifreeze mixture, make sure there are no restrictions in the radiator (tubes starting to plug), drill a 1/16" hole in the thermostat to help eliminate any trapped air, add a coolant overflow with the right cap to maximize water in the system, use a 5 or 6 blade fan and keep all of the shrouding in place.
