The 37 I just bought has what appears to be a radiator and heater core that is in good condition but I'm wondering if I shouldn't just pull them both to have cleaned as a part of general maintenance? I figured this would give ma a chance to work on the ignition system while those items are out being cleaned. Suggestion's?

It is always a good idea to have the radiator and heater core flushed, checked for leaks and repaired as required on a recently acquired used car.

I agree with carcrazy. Have them check it for flow, and advise if it needs to be rodded out. Caution here, as rodding out is a major operation, which sometimes leave you with one or two fewer cooling tubes due to performing the rodding. Not to say don't do it at all, just don't do it if your flow is not already hampered.

Great to have it flushed and tested... however if there is no shop nearby, an old DIY trick was to plug it and fill it with white vinegar, let it sit for a bit, certainly overnight, and then wash it out. Same idea if the vehicle is running and your suspect rust in the system.

I have just cleaned the radiator and engine on a 28 ford, it was full of sludge and rust, talked to the local rad shop, they advised against the flush stuff from the auto stores,(waist of $$ he said) told me to use laundry powder mixed with water. It did a really good job. Lawrie
