Chevrolet - Blazer :: 2002 - Oil Mixed With Coolant
Jul 16, 2015
A co-worker has an issue with a 2002 Chevy Blazer where the oil is mixed with the coolant. My understanding is the usual causes of this are blown head gasket, cracked cylinder head, or cracked engine block. If the cause is a head gasket, they'll probably fix it. Cracked cylinder head makes fixing it iffy. A cracked engine block probably means junking the vehicle. Is there a fairly inexpensive way of determining the cause?

My mothers 95 blazer LS coolant is disappearing. A friend said if it's not on the ground than it's in the engine somewhere. oil pan search looked coffee looking?

I found during an oil change that there is coolant in my oil, I had suspicions of this because of having to add coolant more than I should of had to. There is probably either a crack in my block, head gasket or intake manifold, my question is how can I tell which. I figure that if I preform a compression check it will tell me that I have a cracked block and or a cracked head gasket, what will tell me if I breeched my intake manifold.

2002 Chev trailblazer, I have had the throttle body cleaned.... Sometimes after short stops, my vehicle will not crank, some times I have to step on the gas several times and it will finally crank, it sets no codes, no check engine lights come on. If it sits overnight, or for more than 20 minutes it cranks right up.

I own a 2002 Chev. small blazer with 4 wheel drive available. Largest V-6 available. There is a clunk sound I can hear and feel as this vehicle is shifting OUT of 4 wheel into 2 wheel drive. Going from 2 to 4 wheel drive is perfect. First mechanic (test drove alone) said he would have to tear apart the front transfer case to determine fault. 2nd mechanic (with me along) did power brake slow turns in parking lot. Said the electric shifter was bad and would have to tear apart the transfer case also. Neither mechanic put the vehicle up on a hoist.

I have an 02' Blazer 2Door 2WD 4.3L vortec. Great truck - very low miles. About a month ago the fuel pump went out. She was showing signs / not starting on the 1st/2nd try and finally wouldn't start. It's a 12 year old pump and I was also that guy trying to make til Friday on a quarter tank - so no complaints so far. I checked the relay and fuse, all good there - so I bought a new AC Delco and fuel filter. Drained and dropped the tank, cleaned and dried the tank and installed the new fuel filter. The pump came with a new pigtail - so I wired in the new pigtail, attached the hoses and re-attached the tank. Not bad for 6 hours of work ( first time - don't judge ). She fired right up and ran like a champ / about a week later I stopped and filled up the gas tank. Next day - no start / no whine from pump / 0 psi at the schrader valve.
Assuming it must be an electrical issue - I dropped the tank and tested the gray power wire / 12 volts. But to be thorough / in case I made a mistake / I stripped and re crimped all the connections, heat-sealed the sleeves and wrapped in all in electric tape. Tested the pump - she hummed like a kitty. Re-installed the tank and she fired up like a champ. Drove around a couple of days - stopped and filled the tank with gas. Same thing - wouldn't start right there at the pump. i poured fuel in the intake - she would start and run until the fuel burned up.
No hum from the pump. had it towed home ... again ... began to siphon my now full tank of fuel to drop it yet again. At about 1/2 way , I tried her and the pump primed and she started right away. For the past two weeks I have been unable to make it NOT WORK - but i am worried to go very far , less i be stranded again. on the gauge I get 60 with the key on and 56 running. With the engine off the pressure holds for quite a long time - well over an hour+. So what would cause a brand new AC Delco pump to not work only when the tank is full - then start working when some of the fuel is removed?

I've got a 7.3 tranny that has had ELC Coolant and water mixed in with tranny fluid because of a bad radiator. I drained the fluid from the tranny a week ago and when I pulled off the pan today there is still junk in there. I'm planning on putting in a new filter, gasket and Mercon V but how do I clean the old stuff out of there? Picture.....

2002 F250 5.4 Crew with limited-slip diff.
I put in about a quart of MERCON-compatible this weekend when the level was low. Found out that last tranny flush used MERCON V.
Now I have at least a quart of the MERCON-compatible in with the MERCON V fluid.
Should I not worry and just use MERCON V from now on, or will the two fluids have problems in my tranny?

Been doing a lot of repair's on our 1994 Chevy blazer. It's a 4.3 v6. We finally got her running and now it seems like it can't take high speeds for very long without over heating and eventually smoking some. Had to bypass heater core, it's clogged. That worked with temp. Also replaced radiator and cap. Replaced both heads, took thermostat out. That worked with temp too. It has a new water pump, new exhaust manifolds, has good spark plugs, oil changed and oil filter. Kind of at a loss.

Our 2000 blazer LT 4.3L 4 door 4wd has 190,000 km (about 115,000 miles). 3 Button dash control. Transmission was rebuilt at 100,000 miles (main troque converter spline was shot). The 4 wd will not engage in either hi or lo.
Whether moving or not, press 4 wd lo, light stays on. but nothing happens. I cannot hear the transfer case engaging.
Had a previous problem, (withflashing light): found the vacuum hose under battery case was worn through.
I do have a service engine light on the dash. This may be unrelated, because 4wd stopped working long before service engine light came on. I have changed the Oxygen sensor, but no reset the fault yet. Where to start.

Why will the 96 Blazer not start in the rain? Replaced almost all electric components from key cylinder to plugs. It is grounded somewhere when wet.

I got my blazer look at and here what they come up with so far. Transmission fluid is discolored. Transmission shifts late between 3rd and 4th at 52 mph. Transmission slips between 2nd and 3rd gears at 32 mph. Lock up 41-43 mph in and out. I never told them this but I change the transmission fluid about a week before i took it there and when I check the fluid it was nice and clean and not burned like he said it was. He said most likely it internal damage.for them to take a look in side to see what is wrong with cost me 400.00 and I said no.

my 97 chevy blazer has a lot of cranking first start in the day. I changed the rotor and distributor cap but I don't smell any fuel then all fo asudden it will start. I am wondering is it a fuel relay problem, a fuel filter, or some sort of sensor. when it does start it is very smooth running no shaking or hesitation full of power for the rest of the day starts and stops erands . is it worth buying a plug in code gadget and will this problem show up as a code.

My wife bought a 2003 Chevy Blazer LS 4WD recently and it's nearly perfect except for one quirk. While driving on straight and level roads it will suddenly go left a little and then back to the right. I bought 4 new tires for her and had an alignment done at the same time. The technician allowed me to watch the alignment while in progress. All 4 wheels were connected to a computer and the screen showed the rear was in perfect alignment. The driver's side front was also in perfect alignment but the passenger side was out. That side was aligned and the technician assured me there was no other problems.
On the drive home....it still wandered right then left then repeated every few seconds. I took the Blazer back this morning and they repeated the alignment but it still has the same problem. I have an appointment for Monday morning at a different alignment shop. What might be going on? Everything seems to be tight on the suspension. The vehicle looks brand new inside and out and runs great. It only has 117K on the clock and looks totally original underneath.

Vehicle turns over, but does not start. I do not hear the fuel pump when the vehicle is switched on. Fuel pump was replaced back in December 2010.

My daughter drives my old 2000 Chevy Blazer with a reconditioned transmission I paid for in Aug 2010. The new (rebuilt) transmission is now slipping. Could this be as simple as a fuse (electrical signal issue) or not having enough transmission fluid?

I have a 94 chevy blazer. I purchased it not running. I replaced the fuel tank, fuel pump, fuel filter and plugs. The car ran fine for a couple of weeks. Then it started choking out after putting into drive. i tried to give it gas while shifting and it still died. I replaced the fuel regulator, dist. cap, fuel filter again, and the ECM. It now chokes out while in park. What am I missing?

I have a 2000 Chevy blazer 4.3L 4 wheel drive. 4 of the 6 cylinders are misfiring and the car has completely lost power. Before this issue occurred it was running fine and the next morning when I went to start it the car was turning over and wouldn't start. My dad and uncle believe it's a distributor or computer issue but I would like other opinions about this issue.....
