Chevy Blazer Coolant Leak (Intake Manifold)
I have localized a coolant leak on my 2003 Chevy Blazer to the gasket of
the intake manifold (I hope that's the only leak..) Turns out that this is
common among this particular engine both in the v6 & v8 sizes. The
company's "mandatory" coolant "DexCool" apparently is caustic to the
gaskets and other parts of the cooling system. As a result a class action
lawsuit was filed against Chevrolet (I do not know the results).
The coolant system pressure test kit was rented from O'Reilly Auto
Parts. It required a $152 refundable deposit, but there are no time
I found this site, and it was very helpful. The guy has been generous to
detail his projects.

PART 1 of 3 How To Install Replace Lower Intake Manifold Gaskets GM 3.4L V6
If you are losing Coolant but don't know where it is going check to see if
your oil looks lighter brown and foamy if so you are getting coolant or
antifreeze in your oil and this can be one of the causes. This video is
applicable to the Pontiac Grand Am, model years 1999-2005.
How to Test Head Gasket
** Please see my other videos on this topic* Thx!
This video is intended for those who would like to know how to confirm a
damaged head gasket on a vehicle prior to making the decision to invest a
lot of money for repair. My apologies for the camera focus- next video I
will pay closer attention, but the information needed is viewable. Further
research should be done on the risks of overheating to the engine block and
such. This video is meant to simply show a 'how to' on the test method I
used quite often when professionally working on vehicles, the results of
which are based on chemistry and industry-standards of the time (1990's).
I hope you find this video useful. RI.

About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give
do-it-yourselfers basic instructions on proper vehicle repair and
maintenance. All of our videos show real repairs being performed on real
vehicles by real technicians in a real auto shop. (Repairs are filmed and
shown with the permission of the vehicles' owners.) Although there may be
more than one way to perform any particular repair (and in many cases there
are lots of ways!) we try to focus on the methods that will be safest and
most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex
or dangerous for DIY, or require specialized tooling, expertise, equipment,
and/or certifications. Those episodes will highlight the importance of
hiring a professional auto technician for tasks that are not DIY-friendly,
and demonstrate why such tasks are best left to professionals.

Impala - Valve Cover Gasket Replacement (Front) 3800 Series II
This is how to replace the Front Valve Cover Gasket on the 2002 Chevy
Impala 3.8L (3800 Series II)
This is a fairly simple job, to do this you will need the following Tools:
1. Socket & Ratchet set including 10mm, 13mm, and 15mm
2. Valve Cover Gasket Replacement by Felpro ( Part Number: VS50080R) $14.99
3. RTV Black by Permatex (Part Number: 82180) (not necessary but nice to
4. Torque Wrench that reads Inch/Pounds NOT Foot pounds. Harbor Freight has
them for ($10-$15) (Harbor Freight Tools Part #2696) The one at harbor
freight is 1/4 drive so if you have a 3/8 inch socket set get a universal
adapter set for about $4.
5. Alcohol, acetone, or brake parts cleaner
6. Toothbrush to scrub the valve cover where the gasket will sit
This whole job can be done for less than $50 including the cost of the
torque wrench. I was quoted about $250 just to change the front valve cover
gasket by a local shop.
