Hello all, I’m a real newbie that decided to take on a simple project and one thing lead to another, but I feel like I’m close to finalizing this weekend, if it ever stops raining here in California.
I was swapping out a leaking radiator on my '67 289 C4 automatic and adding a fan shroud while I’m in there. However, I managed to break the transmission cooling lines in the process as well as some of those fittings. WCCC has been super helpful getting everything I need, and I’m awaiting a new, shorter fan spacer, which should be the final ingredient to finish this job. I hope.
I have 3 questions, in the hope of not running into any more compounding issues.
- I have a belt-driven fan (not a fan clutch) … should I loosen or remove the fan belt (or… belts? I have 3?) before swapping out the fan spacer? It doesn’t seem like it would be necessary, but it was a step I saw listed somewhere.
- When refilling the radiator, are there any good, proven methods for ensuring there’s no air in the cooling system?
- Similarly, when I’m topping off the transmission fluid (type F, right?), is there any concern with introducing air into that system … or anything else I should be considering with the transmission fluid?
Thanks in advance for any wisdom. I’ve been lurking on this site since I purchased my cat a year ago, and it is amazing to have access to such a wealth of knowledge and resources from this community.
