Hey i have a 1974 datsun and have taken off the thermostat, and i can see down into where it sits and the passages going into the engine block and it is very dirty(almost looks like rust), and the same around the and in the radiator, I am going to replace the radiator anyway, But can anyone recommend the best possible way to clean out the channels going into the block?. I don’t have a big budget so a do it at home would be the best.
Thanks, Alex

flush the coolent out… they have a flush kit and flush cemicals too… I would first do a full flush and see how you think… now the heater core and the ratator might also be badly clogged to … so you might have to replace them also dont forget about flushing out the coolant reservoir… also when done dont forget to burp the systemHey, thank you i will have to do that, Would it be better to do the flush with the old radiator on so it doesn’t wash all the crud through the new radiator?

Thanks, Alex[/quote]I probably would it would make it easier to clean one my one… so you can clean the heater core my it self the rator by it self and the block area bly it self… I would do a regular water first then if you need use a flush chemicals after if it doesn’t fuly get out

This search should have everything you need. If it takes you to just chrisfix’s channel then you may want to search “chrisfix coolant” he goes in depth making the system like new and makes videos on it that are very thorough. It will answer all your questions.
