General 3.7 ?
Ok, I'm looking at a 2009 Cherokee 221k with a 3.7 . Owner parked it 18 months ago when he bought a hemi version. Says it had started running on the warm end of the scale but didn't overheat(he would turn the heater on and the temp would drop).He did a hydrocarbon test for head gasket failure which was negative.Whilst he wasn't driving it he replaced the water pump, radiator , thermostat etc. Says it's throwing a code for a temp control sensor. Reports no white smoke, I looked at it while he wasn't home, because he is moving (couldn't crank/drive it)with his permission. Oil is dark gray, no chocolate milk, no sludge on the radiator cap or the filler neck, no sludge in the overflow, system was pressurized when I opened the radiator cap. So all of that looks good. But here's the odd part..
The overflow tank smells odd kinda like an old plastic gas can/jug.
Guy said he has drove several times for 20 -30 minutes and let it idle for 45 minutes after one drive with no issues
I thought with the cooling system replacements he was chasing a failing head gasket but I don't really see any signs of it.
The vehicle is in pretty good shape and I'm tempted (he's came down to a grand for it)but cautious. Any idea why the overflow tank smells like that? I looked online and one of the answers was it's near the charcoal vapor system and can absorb the smell.
Any answers/ suggestions
Thanks
