I own a 1995 4x4 gmc sonoma and a 2003 blazer with cooler lines leaking and I am not surprised to hear problems, but on the other hand maybe people with 4.3 engines should lift their hoods every now and again and inspect problems before they have to dish out money.

I bought my 1995 chevrolet blazer one year ago to date. It is a 4X4, with the 4.3 Ltr, LT model. I run fully synthetic oil (mobile one). The only problem I have had is my injector went bad, I replaced it myself, about $500.00 (The cost of the GM part). I could have purchased another brand, it would have cost $250.00. The Blazer had 97,000 miles when I bought it. It has 144,789 on it now and I have never had any of the problems that all these comments have said. If you just check your engine and car on a reg. basis you shouldn't have these kind of problems. At least you can catch any MAJOR problems before they happen and it will a cost a lot less.

I have a 1995 Chev Blazer S series with 4.3 vortex and my oil cooler lines blew off at the crimp. Cost me my engine. When talking to GM Customer Service they said you have to expect things to happen to an older vehicle. They claim they have no problems with these hoses. I am trying to find-out how many owners are having this problem. Hope you can help.

I have also had a lot of the problems that everyone else is having. Since last July I have replaced the fuel pump and sending unit, EGR valve, fuel pump relay, and last and not least, the engine. The oil cooler lines broke, and by the time I could pull over, it was too late.

The problem that I am having now is blowing fuel pump relays. Sounds stupid, but I keep an extra one on hand just in case. If someone is having the same problem and knows how to fix it, please email me.

Hi... My name is Frak from N.Y.C.. 1995 S10 Blazer with the 4.3 motor. I just had my oil service today... and just when I pulled out of the quick lube place, my oil lines burst... I was lucky my motor is OK!! I think GM should inform the public of the bad oil lines. $100 tow fee back home, plus oil change money down the drain... :(

Recently purchased used 1995 Chevy Blazer 4x4 110,000k. Mechanic informed me oil cooler lines leaking. Suggested I fix this immediately. Anybody with any experience bypassing the cooler lines and running like an ordinary engine?

I own (and now wish I did not) a 1995 Chevy Blaxer 4.3

I bought it last year. Since then I have had to replace the transmission (rebuilt $2200.) torc converter ($300.) CV joints (100. each) oil lines coming out of the filter ($54.) and now the fuel pump along with the sending unit is currently being fixed and of course it is only a dealer part. ($380.) All of this plus the cost of labor!!! I will never buy this car again and belive me the dealer knows it. By the way nothing is covered under the warranty!!!

Angry and Broke in NY!!

I, too, have had the misfortune of owning a 95 Chevy Blazer with the W series 4.3 Vortec money pit. In less than two years I have replaced the transmission, oil cooling lines, power mirror motor, rear wiper motor, transfer case switch (now transfer case is also gone), upper and lower ball joints (twice) egr valve (twice), computer, struts, spider assembly fuel injector, fuel pump, fuel lines from the pump, blower motor, A/C system is currently shot, as well as various relays and switches. For the love of all that is holy! Don't buy a Chevy!

Been there done that. Just replaced both oil coolant lines this week, won't even mention $$$ past with my 96 Blazer... Now the mechanic informs me the oil pan is leaking, which for the parts doesn't cost much, but labor$$$ is going to be steep because it's so hard to get to, so he says.. After forking out 400$ for the lines this week I'm seriously considering buying a Honda. I love my truck, but simply can't afford it... Just missing work to go to the shop all the time is to much... Oh and by the way my dashboard looks like a Christmas display, all lights are on, but nobody's home... Lesson learned!!!

I bought a 1995 blazer s series last yr. I have had no major problems to speak of yet. well maybe,I am having trouble with my 4wd, it won't shift into 4HI, but it will shift into 4LO. If anybody knows why please tell me at tony_hoffmeyer@hotmail. I already replaced vacuum switch on transfer case. No luck there. I will keep an eye on my oil cooler lines though. Thanks for the heads up.

My wife had bought our '95 blazer (4.3 w) 4w/d from our local dealer here new in September of that year. After 1 year of driving, (only 3500 miles for her), the crankcase had filled with coolant. The dealership we dealt with had told us they would have to order a complete long block from the factory. They did and we had no problems until recently. Our transmission fluid had crystallized on the dipstick, so, I flushed it. Then the proportioning valve for the ABS went out and I replaced it. Now I am getting the ole "running rich and blowing white smoke" routine. The spider assembly for the fuel injection is next. We have about 80k on it now. It has been a very good truck for us. I am a little leery about every ones comments. I will, however, keep an eye on the oil cooler lines. I did find out that the left bank of injectors leak first. My local mechanic has done about 6 or 7 of these and they have run like a scolded dog after-wards. He charges a little much though. ($550) installed. Seem too high? I would like to have a little feedback from all of you. Thanks for the insight and if I can help in any way. let me know.

My wife and I have had our 1995 Chevy Blazer for almost 8 years now. Like every other car in the world, it has had to have repairs. Last April we had to replace the fuel tank, sending unit, and all the valves, a few other things as well, oil change blah blah blah, $1300.00 job. I will recap the last 3 or 4 months: water pump, the infamous oil cooler line, exhaust, and right now our beloved blazer sits in my driveway, we believe its the fuel pump. Good car, but when one things goes, it all goes. I would love to swap emails with other 95 blazer owners.
