coolant

I have had this oil leaked and today I think I narrowed it down to this T bolt above the oil cooler. Does anyone know what the oil cooler is connected to and what the T bolt is?

Hey everyone, just a disclaimer this is my first car and its the first time working on a car by myself so pls excuse any stupid questions :) (my knowledge is still basic) Car is a '94 Regal with the 3800 v6. The low coolant light sometimes comes on, my coolant level is fine, and its not...

A few weeks back, the "low coolant" light came on intermittently in my 2002 Buick Century Limited. My mechanic added coolant, he did not flush it or anything, he just added it. Since then the "low coolant" light still comes on intermittently. The reservoir tank does not indicate it needs any...

I own a 2004 Buick Lesabre Limited. I have noticed that when I am at idle, my heat is lukewarm. When I am driving and the RPMs are up, my heater’s air temperature rises but is still not what I would consider hot. My coolant level is and has been normal. What I noticed was that my coolant...

I turned my car on for the first time all day today, it's currently 19 degrees outside and I don't have a garage. Maybe the cold has affected my baby in some way. Anyways, I haven't started it since...I got a ride to the AutoZone to get some dex cool coolant because the coolant in the reservoir...

Decided to top off my coolant level with Prestone. The sticker under my hood says that I need to use specifically Dex Cool (orange stuff) but I bought prestone because it said it's 'guaranteed compatible with all cars' so which one is it? I haven't put a lot of prestone in my coolant system...at...

I have a 2010 LaCrosse with ~80k miles. Last week, I had a warning stating Parking Assist Disabled and the car would not accelerate at all with a check engine light. I let it sit for a minute then drove a a close gas station and noticed the coolant was low despite the temperature gauge never...

Hey Guys! Brand new on this forum. I have been around on other forums throughout my years and have a decent amount of experience with cars, obviously, that can always be improved. Right now I have my 04 GS and it has an overheating problem. It can idle but will idle hot and after enough time...

Hello. This is my first post, Hello. I have 1995 Buick Roadmaster with an Lt1 engine, presumably same as Cadillac and Corvette? In any any case, the "add coolant" light came on a while back-- 2 months? And I couldn't immediately detect anything amiss however now the overflow radiator basin is...

Step daughters car has a few issues and I am starting with the water pump coolant system. She had it over heat and I couldn't locate the leak so just replacing items that could have caused the problem. Replaced upper and lower hoses. Replaced thermostat. Replaced radiator cap. Water pump...

Hello, My car (Regal LS 97 3.8L) got strong coolant leak to the ground. Seems to leak from lower intake manifold gasket (middle lower part of engine, from passenger side at least). Coolant reservoir empty even though I added some coolant a week ago. Also there's 'low coolant' light on. I would...

Does anyone know how to access the back spark plugs on a 2011 Buick Lucerne 3.9L V6? I think the motor needs to be pulled ahead, but don't know what needs to be removed to do that. Also how do you remove the thermostat and coolant? Thanks.

The 3.8L engine has 159K miles and runs normally. When started, the coolant temperature starts to climb normally until it hits equilibrium at 183F. This isn't quite right, and it should be about 197F, because that is the thermostat rating. The thermostat was replaced, and that had no effect. The...

Hi- After just finishing a $600 service (:() my Lesabre is now leaking coolant. It just started after 10 minute drive on a 82 degrees (Fahrenheit) day. I noticed that coolant was dripping down under pan behind the oil pan, and seemed to be trickling down from some other part of the engine. Under...

I replaced a starter, upper intake manifold, and pulled plugs to eject coolant on my 2004 Buick leSabre, which unceremoniously died on me the other day due to the mix of coolant and oil in the upper intake manifold. Flywheel spins fine, starter is brand new and replaced, no leaks at gasket after...

Ok. This is for my 1994 Buick Century 3.1 145k miles. After looking through the forums, it seems that I can't find any info on this. My temp light is coming on. It flickers on and off very rapidly as I drive. The gauge itself is fine, although when idling the other morning it shot all the way...

the other day my park avenue stuttered randomly while i was driving. got home and checked the fluid levels and the coolant levels were almost dry. so i filled it back up and the stuttering kept happening at random moments. it would drive fine and then out of nowhere the engine would almost...

I currently have a 2000 Buick Century Limited with the usual 3.1 V6. A few months ago my mechanic noticed the coolant was cloudy, but thought it was from old age since Dexcool gets discolored with age to my knowledge. There was also a milky oily residue on the coolant cap, and the coolant was...

Got a secret-style coolant leak. It's behind the glove box, and what I'm guessing is the heater core. It's been secret because I haven't been able to locate it for months. Overflow reservoir keeps going down almost to empty but through pressure testing a couple of times and checking what I...

I am new here so and though handy not a car 'pro'. I need some help. After removing the plastic intake manifold, and removing the plenum (research said replace those gaskets whenever replacing upper plastic manifold) I noticed a passageway FILLED/BLOCKED with orange-ish gunk (see photo). Is my...
