The engine mounts for the 318 poly fitted to the 407-410 appear to be a rare and expensive parts kit. This seems odd given the likely demand in the US. The Brackets fitted were the Mopar “Floating Power” engine mounts for B body cars. We were only able to find one US vendor selling new parts along with a number posts from US Plymouth owners grumbling about the price. $484 plus carriage, taxes and duty!
For later 408’s, 409, 410 & 411
Suppliers of hubcaps (Warning: Chrome quality might be poor)
According to Girling, this is the master cylinder they supplied for the 411. The Girling master cylinder part number 64068550 cross references to Chrysler UK part number 3058872.
Tools
Steps
For the most part, this is a standard job, except that the emergency brake and the shock absorbers get in the way.
In my case, the car had been rebuilt 14 years ago and then garaged, so bolts and nuts came apart reasonably easily. For most Bristols, you may not be so lucky. On reassembly do yourself or the next owner a favour… use anti-seize compound.
Here is how to identify if the brake lines are blocked and what to do.
Supplies:
Remove the driver’s side (RHD) brake tube flare nut (male) from the T section. Temporarily you will be replacing this with a test brake tube flare nut. BTW, if you don’t know how to flare Kunifer brake line, it’s forgiving and easy to learn. Get the tools and watch a few YouTube videos or buy a case of beer and stop by your brake supply shop half an hour before closing time for a tutorial.
Make up the testing tool:
Begin testing
When doing this job, make sure you know where to buy replacement Kunifer brake lines and matching nuts because most cars will not come apart easily. Nuts may strip, or if frozen may twist the old metal lines, requiring replacement. A brake supply house should carry both the metal lines and the rubber hose. The 1970 411-S1 hose seems almost identical to “H892 Hose for British Ford, Hillman and many other British cars” (try also GBH136). Try Powertrack for parts.
Note: Even if you don’t live in New Zealand here is some useful advice!
Having checked everything people have suggested to improve my cooling with no change, I pulled the rebuilt radiator and the water pump and took them to Trevor French Radiators in Auckland (www.trevorfrenchradiators.co.nz ).
He saw nothing wrong with the water pump, so he suggested that he unsolder the radiator and check it out. First they put a hose into the top, and water flowed out the bottom, but he said that did not mean that it was travelling through the cooling fins. Not sure I understood that one, but as it turns out, he was correct.
For a fixed fee of NZ$90, he completely disassembled it and found the engine rebuild resulted in debris that had blocked the reportedly rebuilt radiator. He rodded it out and soldered it back together. He began at 2 pm and handed it back to me at 5 pm with a fresh coat of black paint. He also recommended that I take a woman’s nylon stocking and put it over the entry of the upper hose to catch any more debris.
He also said that the radiator design was quite good… more sophisticated in construction and should last another 30 years before needing attention.
On reinstalling it, I hooked up a second capillary temperature gauge and discovered that the Smith’s gauge was reading 140 C while the aftermarket gauge was about 93. Without that second opinion, I probably would have presumed I had not cured the problem. Unlike previous runs, the engine was not making those noises related to high temperature, so I am more comfortable that it is running in the 90’s. The fans going off and on seem to agree,
After a few runs up and down the hill, I pulled the upper hose off to inspect the nylon stocking. I found significant debris, blue engine paint and other junk that would have contributed to the need for a 3rd disassembly of the radiator.
Advice to others in the future…
1. When you install a newly rebuilt or cleaned radiator, or if your car has been sitting and may have built up scale in the engine block, use the nylon stocking trick to protect the radiator.
2. If the car overheats, it is easy enough to remove the Bristol radiator and have a shop take off the top to check for any obstructions to water flow. Even if it was just rebuilt, it could be blocked again.
3. Do not rely on the Smiths temperature gauge. The engine block has nearby places to add a second temperature gauge, which costs less and is more reliable than an infrared gun.
4. Other advice they gave was to never use a water blaster that comes near the radiator fins. It flattens and does damage. I’d never given it much thought, but it makes sense. He showed me an example.
Finally, anyone in NZ needing radiator work, these guys are highly recommend. Three older fellows, all white hair, the oldest radiator in the shop was from a 1927 Alvis. Good prices, great service, super knowledgeable.
The following contact details and addresses are for companies who undertake supplying spares and who conduct strip and rebuilding of automatic gearboxes (ie Torqueflte) and Salisbury axles.
American Auto Spares Ltd. no longer conduct strip and rebuilds but can provide most engine, gearbox, starter motors, alternators, etc. which is now the focus of their business.
The others are renovation companies who have conducted strip-down and rebuilding of Bristol V8 gearboxes and axles in the past and felt confident in ensuring a good outcome.
They always prefer to have the vehicle and are quite prepared to remove the gearbox which is taken out from the inside of the car and replaced. Both stated that the final adjustment to the auto-box is best achieved by a series of road trials.
The axle can also be stripped whilst still assembled to the vehicle saving the cost of removing it and the shipment cost of transporting such a large and heavy item.
