Hi guys I am new to the forum, but have been lurking for awhile. I just bought a 92 Eldorado with only 55,000 miles and the antifreeze looks terrible, I want to flush the system but there is a sticker under the hood about some additive that needs to be added to the antifreeze. Is this still necessary or do the new antifreezes that claim to be safe for all types including the dexcool have this in them already?
Also i was looking at the motor when i replaced the serp belt and noticed a glob of gasket sealer near the bottom pulley. If you are looking through the wheel well at the crank pulley it is at about the 10 o'clock position. My thought was possibly someone tried to fix a leak from the timming cover but wanted to see if there was some known issue that would explain this?

Re: New member, New caddy, couple of questions
It's that additive (cooling system supplement aka sealant tabs) that make the coolant look terrible. They turn the coolant a muddy color. These tabs are Bars Leaks tabs (product code HDC). You can get them anywhere, but I would recommend against it. They tend to clog heater cores. GM quit using them around 2002.
Thanks Ranger, that describes it, it is the color of mud and you can see quite a build up on the bottom of the cap and the top row inside the radiator (the level is a little down) I am guessing the combination of this stuff in the colant and the car being driven so little lead to this.
I had a 96 bonneville as well 215,000 and running strong, just too much rust to keep driving so i replaced it with this caddy. So what coolant does everyone use/recomend for the 4.9? The dexcool (pink stuff) or anything approved for alluminum?
Doubt it, they inherited car from 77 year old sister that passed away and only drove it sparingly. Near as i could gather their maintenance consisted of the oil change place. I plan on flushing out the radiator but wanted to know what type of antifreeze is recomended and if i still need the additive. Also trying to figure out why there is the large glob of RTV near the crank pulley as i described in original post.
That is kinda what i was thinking about the RTV, either that or that far end of the waterpump housing, which may be part of the timing cover? Sorry not real familiar with the 4.9 yet. It looks like it is up too high to be the oil pan, i can clearly see the corner of the pan where it meets the block this is just slightly above that.
Yeah thanks, the stuff is gobbed on the end of the waterpump housing near 316 and 319 but on the edge of it not the front surface so i guess it could be from a warped waterpump housing or even that 324. so where does the chain fall in here? Behind 324 or right up against the block after 327?
