Thinking of buying a 2009 grand cherokee
 
I am thinking about buying a 2009 jeep grand cherokee limited with the 4.7l V8. It is in great condition,priced right, my only concern is that it already has 90,000 miles. I am aware these are probably high way miles to be that high on a 2009 model. What are y'all's thoughts on this. As far as the 4.7l goes I don't know much about that particular motor. Thanks for any tips or suggestions.

Going to look at the jeep again tonight. Let me know if there is anything it need to look for. Positive or negative feedback is greatly appreciated.

If you know a good jeep mechanic, who could spout the difference between a WK, ZJ, etc. by memory, pay them to check the vehicle out.

The 4.0 six would be just getting broken in at 90K, don't know the 4.7 at all.

Big thing to look for is signs of a caring owner. When buying a car, just paste the number that makes you feel comfortable over the odometer reading, as it is pretty much worthless for the condition.

Typically places may steam clean the engine, etc. and doll it up a bit, but if you
start looking at the wear items such as pedal rubber, belt newness, and just general crud under the hidden areas inside and outside you'll get a much better idea as to whether the prior owner(s) treated it like a valued vehicle or a disposable appliance.

Hey thanks for the reply, lots of good info. We test drove the vehicle again tonight and looked it over real good. It's super clean inside and out however there is a smell of coolant coming from the front end of the engine once the vehicle is warm. No signs of leaks or anything just the smell. I looked it over with a flash light and the only thing I could tell was that the water pump looked fairly new? Not sure if coolant was spilled on anything creating the smell or what. No signs of heater core issues or typical head gasket signs. Hopefully I'll be able to take it to a good mechanic to look it over.

Anyone have common issues with the 2009 4.7L? From the reading I have done it doesn't look like HG are an issue unless the vehicle has been overheated extremely bad. No signs of the HG being a problem. My wife and I are really concerned about the coolant smell. It's going to be a vehicle for her and don't want to make a mistake buying it and it crapping out on us. I'm going to see if they will let me take it to a mechanic to have it looked over. In the mean time if you guys have had or heard of similar issues let me know.

If they DON'T allow your mechanic to give it a good inspection/test, run, do not walk away.

The coolant smell could be due to many things where a good mechanic could point out the ones useful for negotiating price as opposed to those which should make you walk away.

- hoses soft, old. No biggie, just rehose it which is a good idea on a used jeep anyway.

- water pump weeps. Rarely causes a notable smell unless you are a bloodhound

- thermostat. Just replace it and gasket.

- radiator. the plastic tanks have a bad habit of cracking down at the bottom.
Here, you would see wetness along the frame member under it.
As long as the engine has good compression, aftermarket radiators
are plentiful, although a tad of a pita to swap. Drop the price a few
hundred or walk.

- Heater core. Lift the carpet under the heater assy on the inside. Any wetness
would be a red flag, and it is a tad more of a pita to replace. Ask
the mechanic how much....

-- heater hoses... same as radiator hoses.

-- freeze plug. More of a red flag that something is not taken care of than any big
deal to fix.

-- radiator cap more common than you'd think.

-- overflow bottle. Nasty habit of almost invisible cracks, pluggable with a GOOD glue gun or just replace. Check the hose to it.

Definitely run an engine compression check to make sure it isn't something horrendously expensive. A simple pressure test, with dye, of the cooling system
should be reasonably good for anything else.
Always figure on spending about 10% of the purchase price to bring a used vehicle up to snuff.
