#324 of 3676 Oil Cooler Lines
Jan 10, 2002 (1:32 pm)
To all of you thinking about purchasing a Chevrolet Blazer of the 1999 vintage: D O N' T...
I have owned mine since February of 2000. Below list shows the problems that I have encountered so far:
1. left front pinion seal: replaced twice
2. fuel sending unit-warranty repair
3. fuel gauge-warranty repair
4. oil cooler lines: replaced both lines twice
warranty repair first time,
second time out of pocket $$
5. intake manifold gasket replaced-out of warranty
6. dead battery: warranty repair
This is all that I can remember at this time. I am sure that if I think hard enough that I will remember additional things that I have had to get fixed. The last repair occurred last week when I needed the oil cooler lines replaced for the second time within 18 months. There is a 12 month warranty on GM parts so I was forced to pay for the second round of replacement lines. This is the BIGGEST piece of American made junk ever created. Please stay away from this vehicle if you are thinking about a purchase. My personal opinion is that if you haven't had any of these problems so far; you will at some time in the future.
#325 of 3676 Coolant smell
Jan 10, 2002 (4:48 pm)
I had a problem with my 96 Jimmy not delivering enough heat in the cabin. I think the problem started a couple of years ago. After changing the thermostat to no avail I decided it was time for the 5 year change of dexcool. I flushed out the cooling system and even took the heater hoses off the engine and flushed the heater core with a garden hose. I noticed a lot of slime and crud come out of the heater core. Now the heat works wonderful, but I notice a coolant smell anytime the heater is on. I can't find a leak anywhere. Is it possible that flushing the heater core "unplugged" some pin holes and now it is leaking enough to smell, but not enough to see on the floor? Is there any way to leak test the core without taking the dash apart?

Why did you need to have the intake manifold gasket replaced? Was it leaking coolant?
#327 of 3676 MRCHW, about the sticky accelerator,
Jan 13, 2002 (6:40 am)
I have a 99 S10 ZR2 P/U that also HAD a sticky accelerator..
Look at the accelerator cable connector at the throttle body on top of the motor, you will see the lever that you can move with your finger as if you wanted to rev the motor while standing by the engine. It seems to have a magnetic connection where that lever touches the mechanical stop, that magnetic connection made the lever "sticky". I put a piece of electrical tape over the stop so it was no longer a metal/metal contact, now I don't sometimes "jump" out of a parking place like it used to want to do
Hope this helps

As you suspect the heater core may have a leak.
You are leak testing the heater core every time to run the vehicle up to normal operating temperature and pressure. Are you losing engine coolant?
#330 of 3676 Chevy Blazer 1999 LS 4x4 (push button for 4x4 doesn't)

I have had my 99 Blazer for two years and the push buttons to change from (2HI) to (4HI) or (4LO) or (auto4WD).(4HI) only blinks and the light never stays solid --but it seems to be in (4HI)or (4LO) but it just keeps blinking(they will blink for as long as I pushed (4HI)or (4LO)-- until I push (2HI)again- and I'm back in (2HI). No other things wrong just the blinking for (4HI) or (4LO)when pushed.When I push the (auto4WD) button it will blink for a while then just go back to (2HI)by itself. They stop blinking when I push (2HI) and its solid and I'm in (2HI)..
Any comments would be appreciated.

Thanks for the feedback. I have since confirmed that the heater core is leaking and have an appointment to have it replaced. The best price I could find was $420. They all say it is a long and difficult procedure because the dash has to be removed. I have talked to several mechanics who say the problem is the GM dexcool. After surfing the net looking for dexcool I tend to agree there are some issues here. I complained to my GMC dealer, but he could only provide sympathy. I have a suggestion for everyone with GM vehicles about 96 and later: don't wait for 5 years to flush the cooling system. I suggest 2-3.

#333 of 3676 Disc Brakes
Jan 21, 2002 (10:52 pm)
Hello all. I've got 2 '98 Blazers, 4x4 LS and LT. I pull a 4500lb boat w/trailer. both trucks have just about 70K miles. I am just changing the brake pads for the first time since owning it. problem i'm having is that i can't take off the rear brake rotor. the brake rotor has a score and i'd like to have it resurfaced at autozone. i've got 4 wheel disc brakes. the rear brake rotor is the drum type. i just can't pull it off like the ones in the front. i'm thinking maybe the parking brake is holding it. i tried tapping it with a mallet lightly but it's the same thing. is there something i'missed? calipers are already off the hub. anyone have done this before? any input on this matter is greatly appreciated. thanks.
