Well, first off, nothing is guaranteed in this life except, of course, death and taxes (at least death doesn't get any worse when Congress meets!). That being said, 150K isn't that big a deal anymore. They just don't make stuff like they used to...they're better! There are a few basic things to do to have many more miles and years with your Blazer. First and foremost, change the oil and filter every 3,000 miles (5,000 if you use synthetic oil), make sure the oil level doesn't get below the bottom mark on the dipstick, and make sure the coolant doesn't get too low either. It's a good idea to check the oil level each time you fill up with gas.

Highway driving is easier on the engine than city driving, so if you've done a lot of highway driving, you should easily be able to get twice the mileage you have on it now. But, even if you don't, if you go easy on the acceleration and keep the fluids up, you'll have several more years left. And, watch the guages. If the engine gets hot or the oil level gauge drops to zero (or the light comes on), stop immediately!! Continuing to drive without oil pressure will guarantee you'll need a new engine, as the existing one will sieze up. Of course, this is highly unlikely as the oil pump is a simple device...it will probably never happen, but always check the guages. By the same token, if the coolant level gets too low, the engine can overheat and usually and that leads to a blown head gasket (it goes between the block and head of the engine). It's repairable, but a big pain in the... well, you know.

I hope this answers your questions. Please remember to rate my answer. Happy motoring!

I have a 2006 Mitsubishi Endeavor with about 130K miles on the clock. How much use can I get out of the timing belt - I am a gentle driver?


No matter how gentle you are with your vehicle, the engine and all rotating parts still rotate and eventually wear out or get fatigued, it is recommended to replace the timing belt every 60,000 miles, I guarentee you it will be ALOT cheaper to replace the timing belt, than have it break and cause catastrophic damage to the engine internal parts, which odds are you would have to replace the engine because it wouldn't be worth investing the money to fix that engine after a timing belt break!
Good Luck !

'97 Chevy Blazer LS. 77 K miles. At what mileage is the suggested timing belt change for these models or is it change them when they break?


Chevy blazers dont have timing belts they have chains. The chains get noisey on some engines that are run hard or the oil changes are missed. Sometimes these engines live their whole life if not run too hard without changing the chain. Noise lower gas mileage uneven idel hesate to accerate. These are all things that happen over 100 thou miles. Many go way farther with no problems

I have a 1999 Blazer 4.3 V-6 and am wondering what type of Anti-Freeze this vehicle uses. The green or the pink.


Dexcool is the correct antifreeze for the engine, but you can have it flushed out and use the green coolant if you prefer. The dis advantage is the green coolant needs to be replace at about 50,000 miles and the dexcool is 150,000 miles.
