C4 Oil Cooler / Filter
« on: February 18, 2020, 05:52:18 PM »
On C4's equiped with the KC4 Engine Oil Cooler look out for the fitting on the bottom of the block becoming corroded and blocked.

It is 1/4NPT to Barb fitting.
Whilst 1/4NPT fittings are avail, it would appear that this particular fitting was dreampt up by GM.

The catch 22 is that after buying several bits, the barbs all seem Way Toooo small and slop around in the hose.

The hoses came from Corvette Central - specially molded for the purpose. But whilst the fitting is shown on many diagramms, it it not listed as a purchaseable part.

Been thru all my Odds and Sods, and thru Rocket Ind cattle dogs.

Saw one part on Ebay - ex US at ~ $12US plus $42US postage !?!?!?!?!?LLnvv ..

I wonder who may have a Lathe ummmmmmmmmm.?......
