I've recently changed the engine in my '69 4 door Minor for a 1275cc Morris Ital A+. The engine runs well, but before it was replaced I cracked the block drain plug only to be faced by a solid wall of chalk. I removed this concretion the best I could using a screwdriver and replace the drain plug.
As the engine was a bit of an unknown quantity, I'm thinking of flushing the radiator, heater matrix and hopefully the block. I know that from various posts on the forum, people have recommended using either kettle descaler or drain cleaner to perform the flush. I have, however, some Holts Speed Flush and some of the Holts 2 part Rad Flush, which I purchased before reading the forum posts
.Does anyone have any experience in using either of these products and which would be the best one to use. The radiator is only 3-4 years old, as it was replaced when the car was rebuit due to the original radiator experiencing severe "fin rot".
Also, is it possible to back flush the system using a bucket, as I'm not sure that the garden hose will reach as far as the car, which is parked in the road.
Regards
John
