The car was missing alot about 2 weeks ago and suddenly stopped. I have been told it is the fuel filter or pump??? I am new here and will have to get it towed in the morning but also dont want to get taken advantage of. Any ideas??
What code has been set? Autozone will check for you.
Another more common source of a leak is the thermostat housing to intake manifold gasket. Sometimes they leak a little after they have been replaced until the gasket swells and seals. Especially if the gasket was installed wihout any Permatex High Tack sealer or it was tightened incorrectly or not tightened enough. Many car owners or shop technicians will not tighten those enough after the thermostat has been replaced and the two thermostat housing bolts will need to be snugged up a little to stop a coolant leak. The aluminum thermostat housings are easy to break if they are overtightened. I wish shop technicians were as cautious with oil pan drain plugs.
Other common sources of coolant leaks from the front ot the engine are:
1.) Upper radiator hose to thermostat housing connection.
2.) Lower radiator hose to water pump connection.
3.) Heater hose connections to the water pump and intake manifold. .
Thanks for your help
Thanks but it more than likely a intake manifold problem
My bets are still on the water pump.
The class action suit has settled and the suit is closed. The claims were affected by the GM Chapter 11 bankruptcy. ( www.dexcoolsettlement.com )
Why risk using Dex-Cool when the green stuff is a tried and true antifreeze when used as instructed?
Because if you don't get every bit of that Dex-Cool out of the system, you will have problems. Like gasket issues and blocked cooling passages.
The big issue with Dex-Cool isn't so much the product, as the change interval that GM published. No way do you leave this stuff unchanged for 5 years 100K miles. I have not come across any issues with 60K changes. The 4.3L intake manifold gasket issue is not coolant related, but an issue with the proper torque of the intake manifold and it's flexing/distortion over time. Not all engines are affected (I have two such engines, one with over 90K and no issue) but some have failed in less than 60K miles, most around 70-80K.
I agree that the standard ethylene glycol antifreeze is good, and has been for years. As long as it is changed at least every 30K or 24 months, it will provide good service. What some folks don't realize is that the antifreeze properties are not the issue, it is the anti-corrosive chemical breakdown that causes problems. Nowhere was this more evident than in the mid-80's GM cast iron engines where the freeze plugs would rust out and start leaking. PITA to fix that "little problem". The parts would cost a couple of bucks, the labor hundreds!

I have a 1997 Blazer 2DR 4X4. I bought it about 1 mo ago and have had nothing but problems. My biggest problem is I cant seem to get it inspected. I have over 200 miles on it since I replaced the battery but when the Mech Hooks up the "DREADED" computer all we get is a reading that says Not Ready To Read. any suggestions? If I cant get it inspected I cant use it. I do have some small electric problems IE:
My compass is backwards, my fuel gauge doesnt work, and I dont believe my temp gauge is working.
It's to the point were I won't dart in front of traffic unless I have plenty of room. This way I won't interrupt the flow of traffic and get rear ending. I never know when it will sputter.
I took it to a good repair shop and they cleaned off a sensor and it helped for a week, then it went back to the stalling/sputtering. I hope whatever the problem is it will be a cheap fix. I just spent $800 fixing something elese. I did not mention the stalling, I was still in shock from the $800 problem.
It's driving me NUTS and not doing my pocket any favors either.
Thanks for any suggestions
The ICM is sensitive to heat and ground and will intermittenly fail when the heat is excessive there high resistance to ground. .
New fasteners provide a good electrical ground for the ICM and should be replaced when the ICM is replaced.
