Water Pipe for 275 GTB, GTS

Here are some water pipes I just finished making for Ferrari 275 GTB and GTS, they fit all of the 275 series of cars except for the GTB/4′s. This piece connects the long pipe that runs under the exhaust header to the thermostat housing that’s bolted to the radiator header tank. Like all of the other pipes I make, these are 304 Stainless Steel so they will last forever!

Thrilling

I know, this is such a thrilling topic. I had to make brackets to attach a modern cooling fan to the radiator of a 250 Pininfarina Cabriolet. The part that’s the most exciting to me is that box board material for making templates, I love this stuff because it’s easy to cut while being rigid enough to handle bends and maintain shape. Whenever I get FedEx envelops or a Certificate of Authenticity from Porsche (which is where this box board material came from) I save it in a secret location so no one else can steal it from me. When you combine this box board with a sharpie marker and sharp scissors, anything is possible.
The box board template is a mirror image (fits left and right) so I sandwiched it on the top of two sheets of 12 gauge steel and traced the pattern with the plasma cutter for the final piece.

Jaguar XKE Series II Fans

Reversing direction of Jaguar XKE cooling fan motors

With a test light and a few long leads, I can diagnose most electrical problems on old cars without too much drama since they have very basic relays, lighting systems and motors. Figuring out electrical problems empowers me since there aren’t many places for gremlins to hide. This keeps me feeling productive.

A 1968 Jaguar XKE came in with worn out radiator cooling fan motors so I sent the old motors to a supplier as cores and they promptly sent me a pair of overhauled ones. When we plugged them in, they turned the wrong way. So, I called the supplier who apologized for the error and then regretfully informed me that the correct rotation motors are on back-order for months or more! The owner wanted the car ready for a show in a few days so we switched the wires thinking that they would turn counter-clockwise rather than clockwise but they didn’t! I disassembled the motors thinking that if I changed the magnet, maybe I would get the favorable result but it isn’t a permanent magnet, its an electro-magnet, the motor continued to spin clockwise.

After some head scratching, I realized that I had to reverse the wires internally to send current both through the armature and the magnet in the same direction. This got me out of hot water by cooling the old cat’s engine just the way she likes it. It took me some time to find the solution because I couldn’t believe that a simple motor like this needed internal modifications to change direction. Learning all the time…

Another Jig for Stainless Steel Water Pipes

If I were making a production run of something, this isn’t how I would do it. Ferrari made thousands of “250″ series cars all with these goofy water pipes for the cooling system which vary drastically throughout the 10 year production run.  They are so complex and hard to duplicate that re-making them nearly impossible. This “J” shaped pipe has a compound curve with barbs that have to be welded on in exactly the right location even though they appear to be stitched on at random locations. If they are off one millimeter, they will hit the oil filter or run into the fan.

These pipes are for the Lusso/GTE series of 250, but I can make a number of other styles from 166 up through the 275 cars utilizing my incredible and growing stockpile of bends and flared ends. Right now I am making a short run of the water pipe that connects the thermostat housing to the engine on a 275 GTB/GTS Two-Cam engine.

MG’s, Early and Late Production

Here is an early production MG, the model PA and one of the last of the “cycle fender” style cars, the MG TF 1500. These cars are a blast to own and live with because they are so easy to drive, cheap to keep up and have a great look. We did a drag race with these two cars but couldn’t see who was faster because of the insane amounts of tire smoke.

Replacement Water Pump Castings

The new castings arrived and they look perfect. I wish we could get new parts like this for every component on Ferrari engines.

We also inquired about getting a new engine block for this project since the original may be compromised from all of the corrosion, but after hearing the price, I think we can fix the old block!

More Stainless Steel water pipes

We have made jigs for re-producing the often rusted and leaking water pipes for Ferrari 250′s. These are not  perfect reproductions but now that we have the tooling we can easily make an exact copy if anyone is interested. We are using Stainless Steel so they won’t rust away like the originals.

Aluminum Castings

We typically have to clean up and weld castings to make them serviceable but these 250 water pump parts are too far gone. The material around the 6mm stud has deteriorated so it just fell out, and the pitting at the impeller surface negatively effects the flow of water through the engine. The bearing support plate is trash, it must weigh 40% less than it did when new.

With corrosion this bad on these castings, imagine what the inside of the engine block looks like! We are pulling the sleeves right now in order to inspect the block and possibly replace the sleeves if the wall thickness has been compromised by the rust.

I ordered some brand new castings to replace these and am anxious to see how they look and fit.

Newly cored Radiator for GTE

Flat fin radiator

Flat fin radiator

Here is a brand new correct type flat fin radiator core all assembled with tanks and side brackets for a Ferrari 250 GTE. These cores are so nice and we will cover the core in cardboard to prevent bending the delicate fins. This radiator has the bottom tank that was all hammered and beat up and corrected and documented in an earlier post.

Radiator tank for Ferrari 250 GTE

Ferrari Brass radiator tank

Ferrari Brass radiator tank

Ferrari radiators are a thing of beauty, huge thick flat-fin cores and beautiful pressed brass tanks. The lower tank typically gets hammered from lifting jacks, and curbs as well as tow truck hooks. This was a badly dented tank but not as bad as we have seen, after some controlled hammering, this tank looked perfect and is ready to solder onto the core.
