2001 Malibu fuse and collant question

[alyssawb]

My Malibu keeps blowing the 20 fuse under the hood which powers the lighter and the powerpoint. I've replaced it about five times now, and it seems to only last a week or so... is there a bigger problem that needs to be fixed?

The intake manifold has a leak again... which we already got replaced for around $400 about two years ago so this time i'm just keeping an eye on the coolant. I've added water twice(there seems to be a small quantity of antifreeze still in it). I bought some dex-cool, but wondered if there is a certian ratio of antifreeze to water that should be in it??

Thanks in advance for any and all advice

really depends on where you're at for the mix...but i usually stick to a 50/50 mix. as for the fuse, remove ashtray and see if there is a coin or something bouncing around in there, or any other metal object. do you use the lighter a fair amount, or use the plug for a cell phone charger? if so, try not using for a week or 2 and see if fuse lasts longer. otherwise would warrant checking out more if it realy bothers you.
