Replaced upper intake gasket, still losing antifreeze this time not visible


Did you change the Plenium also / if not you should of, these also go bad and leak antifreeze through to egr port , most parts stores will recommend you change it too, i've done several and they look good but the plastic turns soft and leaks coolant to egr port.

I over heated my engine and it will not crank


cylinders are full of coolant...Hydrolocked, time for intake and plenium gaskets and prob. lower intkes while you are at it. Dorman makes a nice replacement set the intake plenium with gaskets needed to install, make sure you replace the actual plenium., first I would pull all spark plugs and roll enjine over with plugs out to be sure that is problem 99% sure it is....pretty common in 3800's check your oil for antifreeze , if it rolls over and you decide to fix top end, CHANGE YOUR ENGINE OIL AND FILTER too cause antifreeze and engine BEARINGS don't Mix well shortens life of them.

Radiator overflow container always empty


better change out your Plenium (Intake) before it ruins your engine ! Part is about $125.00 and comes with gaskets and a new Intake and new EGR Tube you replace also, what it is doing is leaking internally and burning it, it will eventually start to miss and quit on you Hydrolocking the engine. water does not compress in cylinders. If you are lucky you won't have to do lower intake gaskets or head gaskets......But get it fixed before too LATE !

How do I replace the thermostat on my 2000 Buick Lesabre Limited 3.8 liter V6?


find where the upper radiator hose goes into the engine. the thermostat lives under that cover. drain some coolant from your COLD engine(to avoid burns) remove the bolts and replace the thermostat. be sure to also purchase a new gasket. some 3.8 s use both a rubber and paper gasket. parts store should have listings. reinstall, refill coolant, and run engine, topping off coolant as engine warms. some have small bleeder screw on the thermostat housing to air in bleeding air while filling. just crack it open until steady steam of coolant comes out. test drive and recheck coolant level. recheck coolant and adjust level for the first few days.

White smoke from buick tailpipes, wont start


I had the same problem with my '87 Buick LeSabre 2 years ago. But it didn't seem to fit right, the car was running fine up until it just didn't. I had 3 professional mechanics swear it was a blown head gasket. I researched thoroughly and found out this particular engine make has a DEFECTIVE upper intake manifold which can break down and cause coolant to leak into oil, simulating a blown head gasket. The NHTSA had issued a recal on SEVERAL GM cars with this engine, EXCEPT for the '97. I filed a complaint with the ODI and as of today it is now COVERED as a "Defect & Recall". NHTSA ID number 96V116000. This MAY be your problem if it is NOT the "usual" blown head gasket. Hope this helps.

Coolant disappears with no visable leaks.


This is what they are talking about, a major problem for GM. Google it and you will see how big the problem is. Don't drive the car until you fix this.

The 3.8-liter V6 may leak coolant into the engine from the intake manifold. A new gasket kit, revised throttle body nuts, and sealing compound is available.

Coolant dissappears with no visable leaks.


Yes...sort of the same...you are getting coolant in the motor...like a hairline crack in the head.
