Also remove the water inlet manifold and flush from there use a stiff bottle brush in the intake hole to remove anything around the cylinders. I recall flushing my seven radiator etc  with the radiator still coupled and when no improvement I removed it and found the bottom tank and outflow pipe full of rusted scale etc.

Sorry I don't remember who but someone recently posted a pic of an ingenious temporary tank to replace (and thus save) the radiator while doing this. Might be a bit of work though.


This has worked well, as has patio cleaning acid used in the rad (caution needed there - it's a last resort, not without risk but it shifts crud)

This reduces all " crud " to a fine dust which can be washed out. Crankcases and aluminium casting can also be treated in the same way but the temperature can affect any previous heat treatment. I have used the process on both block and cases with 100% results.

Local to me are Lenton Treatments of Leicester who are RR certified and always most willing to help I'm sure there must be others around the country.

I've not used Lenton myself but was admiring a block they had done for someone else last week and it looked a great job.

Just to finish the story - at least my part of it- I finally bit the bullet and had a new radiator core fitted by a local firm. The RP is now running normally

It's the only way.
