1999 N*

1) Is ANY coolent use normal?? I mean about 1/2 - 1" in the tank over 3000 - 4000 miles or so?

2) Where on earth is the tranny dipstick?

Thanks in Advance.....

Your coolant usage is a little high, yes.

The trans dipstick is on the top front corner of the transmission. Black round handle looking thing. Check it idling when warm, in park, on a level surface.

1) No.

2) Look under the intake ducting. It is not a conventional "dipstick" like the oil stick. It is a cap with a stick, like the P/S.

Hummmm....the coolant was changed at the Caddy Dealer about 40k miles ago. It is still nice and red. However I do sometimnes think I smell that hot coolant smell every now and then (it is very faint, I have a sensitive nose) when I'm driving. I can smell that smell in a lot of cars I have been in.

Maybe I have a small leak somewhere on the engine. There are no drips. Is is possible the waterpump may be weeping a little when it is running. I do here a little "whine" noise off and on from the belt area. WP was changed about 40 k ago as well.

I also may be off a bit on my estmate of useage as I checked it sometimes on a small slant, I'll keep a good watch by checking it here at work (very level).

Thanks both for the tranny info.....

Remember that the "tank" is part of the pressurized cooling system. You do not want to remove the cap when it is hot. If you check it at work, check it when you leave work when it has cooled down. Fill it about 1.5 to 2 inches from the cap when it is cold and always check it cold.

If you are smellling coolant you might have a seepage somewhere..... Look around carefully. You could also get a coolant system pressure pump and pump up the system when it is cold to exacerbate any leaks making them easier to find.

Was the cooling system sealer added when the coolant was changed at the dealer?? If not, then disconnect the upper rad hose at the engine end, pop 3 or 4 of the coolant supplement pellets in and reconnect the hose. That would seal up any minor seepage at a gasket or casting that might be occuring.

Thanks for the advice Chev,

I can assume (bad idea huh?:bigroll: ) that the pellets were added (it was before I got the car) since it was done at the local dealer, and there is also that big yellow sticker right at the radiator to remind them. However if I do verify some seepage I will check back with them. All I have is the history printout on the car that does not go into detail on what they did or did not do on any particular maint. job.

If there is any doubt about the supplement/sealer just add some more. Unless you start using a coal shovel to install it, it really won't do any harm. It is perfectly fine to put 6 pellets in (a 4.1/4.5/4.9 used 6 pellets from the factory) so even if three were put in with the coolant change adding 3 more to be sure would not hurt a thing. In fact, it just adds more protection from seepages and leaks.

The only bad thing about using the supplement to stop seepages is that you do not want to mask an impending catostrophic failure (like a hose splitting or clamp failing or ????) with the sealant only to have the part fail completely and leave you stranded. If there is suspicion of a leak or seepage it is a good idea to identify the source and then decide if the sealant is an acceptable means of stopping the seepage. If the system had the sealant in it from the factory and then it was not replaced when the system was recharged with fresh coolant it could have opened a previously sealed porosity or seep from a casting. That is what the sealant is for....sealing up microscopic seepages from gaskets, gasket surfaces, casting porosities and voids, etc. Use it.

good point. Next chance when it is real hot I will park it in the sun, pop the hood, take the cover off and stick my nose and eyeball around as much as I can (without getting burnt). Maybe I can see it. If nothing else I can add the 3 pellets, after it cools of course. I have heard here that Bars Leak PELLETS (NOT liquid) is the same thing as you get from the dealer.....true??

Yes, the Barsleaks tabs (HDC) are the exact same thing that you get from the dealer.

FWIW, I used to have a faint coolant smell on my '97 Deville when I pulled in the garage. Searched for a long time before I found some very minor seepage along the bottom of the water pump cover. It is imposible to see, but when I felt down there my fingers came out damp. I still have the gasket on my work bench. It was so minor that I never got around to replacing it.

Yes Ranger I know what you mean. I had a 87 Town Car (that I sold and bought this 99 Concours) that every time I pulled in the carport I could smell faint anti-freeze. Never found a leak, added just a little coolant every 3 or 4 months........ran like that for years, never did drip anywhere......

The BarsLeak "golden seal" powder is the same stuff, yes. And BarsLeaks also markets the sealant in the same pellet form as the GM coolant supplement.

Just be sure to put the sealant directly in the radiator hose. Do not be tempted to just dump it into the surge tank.

Got it...:thumbsup: Top hose, engine side......

I have a 2000 Deville DHS and I was told by the mechanics that there is no dipstick for the tranny since it is a sealed system. The only access to the cooling system is the cap on the overflow tank and there have been problems with cap leaks according to the Cadillac serve bulletins. Loss of coolant is not normal and may be a sign of the problems that many of have had with head gasket leaks. See all the forum entries regarding overheating and head gaskets. Sorry to be the bearer of bad news but it's best to have it checked now before the problem causes constant overheating, loss of coolant and then complete engine shutdowns.

Well looky here. I am no Cadillac service specialist, but there seems to be a dip stick for the trany here. Maybe you need to frequent a different service department.

Time to find another mechanic. Perhaps your head gaskets were not bad after all.

My wife's 2002 Explorer has a "sealed transmission" and thus no dipstick. Dumbest thing I have ever seen. I realized right away where the dipstick was...behind a desk in Detriot designing Ford transmissions!

The CTS has a sealed transmission and is assembled in a cleanroom. CTS transmission problems are just about unheard of. The idea of reducing the introduction of dirt into the transmission is a good one if the transmission is bulletproof to start with.

pray your seals don't leak...

$3000 bill to remove and overhaul transmission because you can't add fluid...

You can check and add fluid. You just have to know how and where. I refer you to page 7-379 in the Helm shop manual.

Requires a special tool and equipment to do it on the Ford. Still seems dumb to me...maybe that's because I had to spend $2000 to have the tranny rebuilt...

My daughter had a VW Passat. No dipstick and they do have trans problems. Hers went @ 60K.

The PIA part about the CTS is that you have to have it on a lift while running. From there you take a filler plug out and look, just like any old manual.

OK found the little tranny cap/dipstick. Now since you check fluid with the tranny HOT and the engine Running, and since this cap is tucked away in a place that a squid can hardly reach, I will need a pair of asbestoes gloves to check my tranny.....:thepan:

Naw, just check it a few times. Then you'll have leather hands. The blistering goes away after day 9.

^^ That's horrible :)

My dad's corvette is automatic, and you have to get under the car, while its running, to check the fluid.

Whot the f**k designs these things? People who want the owners to die while checking the damn things!!

It's not that complicated. Just rotate the air box up in the air and you have perfect access to the dipstick. The dipstick does not get that hot; just turn and pull. It's that simple.
