Hit a deer, put it back to together, now its overheating?
Hey y'all, I'm new here. I have a 1996 Grand Cherokee with 245,000 miles on a 4.0L. I am not a great mechanic so all the help I can get is greatly appreciated.
My question is: I hit a deer a few months back. I took it all apart and ended up replacing the Water pump, fan clutch, fan shroud header panel, hood, grill, radiator and thermostat. I test drove it the other day and its running rough so I am thinking the timing chain might have slipped on the impact (I was doin about 50) but the real puzzling part is that it's still overheating even with a new water pump, thermostat, and radiator?
Could this be linked to the timing chain slipping?
Plus when it overheats the first place I see steam is at the valve cover on the drivers side towards the middle.
pop radiator cap
let it run untill it reaches operating temp and t stat opens
you will probably see and empty radiator when this happens
top off the radiator and repeat until the radiator stays topped off at operating temp
V8 zj at 6" . Double tri rear and true 3 link front. Stretched to 108"
I thought you put the Deer back together and it had s high temp.
Rough running could be from disconnecting the battery to do the work. Mine ran rough for a couple of days after I did the pump I took it on the highway and it is smooth now. Does it feel like a miss at speeds or just rough at idle. Chances are if the chain slipped it would be back fire and not running. Very rare does it just run rough.
I would also check for cracked vacuum lines

An even easier way to get the air out of the system is to spend 5 bucks and install a flush and fill kit on the highest point of the cooling system (a heater hose). Remove the flush cap, and fill the radiator until the coolant just starts to come out of the fitting. Cap it, fill the radiator the rest of the way, and you're done.

hey y'all the jeep is back on the road and working great! Thanks for all the advice! I took it out this evening after I burped the system. Drove it through town and down the busiest area with lots of stoplights then out on the highway for about 10 miles stopped and got gas and checked the radiator again drove the 10 miles home and no problems! had it up to 80+ mph (keeping up with traffic and all lol Thanks again y'all!
