1994 Grand Cherokee Limited Overheating
Ok search tossed back 250 results for Overheating. I read most that had that in the title. I'm guessing its air and I'll keep trying to bleed until I get it straighten out or a response to look else where.
1994 Jeep Grand Cherokee Limited 4.0 I6 Auto Air All time 4WD 140,000 miles.
Bought used two years ago and have done my own maintenance tackling each little thing in time. It hasn't needed much. I had a "shifting issue" that turned out to be a dirty throttle position sensor. Cleaned and good now. Anyway When I bought the Jeep the gauges were well... Not accurate. Volts never over 12 I tested it at the battery and I'm getting about 14.4 so I'm charging. Oil Pressure when key is turned forward, engine still off, goes past 80, inop? Temp gauge has been know to run well below 210 and at times just above not much. One time last summer it was 95 in traffic I turned the heat on to keep it from going too hot. It was almost to the next line. I would sometimes have the low coolant sensor go off yet, when I'd pop the cap it would ave fluid in the neck, it would even have some near the add mark at the over flow. I'd read it could be a poor solder joint and not to worry.
Ok two nights ago driving home I see smoke?? from behind me, I'm doing 60ish its dark and it looks like mist? I notice the temp gauge is climbing past the 210 mark, I'm just a few miles from home and I turn on the heater full blast, I had it in when I started out and it was blowing hot now its cool. I get off the high way and am about three miles from home. I turn into a parking lot and as I do it stalls the needle is pegged. I get out pop the hood and there is anti freeze all over. I see it seem like its come from the radiator so I lock up and walk home. Next day after work I drive over and it fires right up. I toss in a gallon of water and it all it took? drove home and put it on the driveway.
Bought a radiator today from Pep Boys, install went OK. PO must have had trans issues because the trans lines were cut. I had noticed the cut lines but thought they ran to an additional cooler in front of the condenser coil. After I tried in vain to use the quick release tool to release the fitting even out of the engine bay I can't get it off. I notice this. Cool. I figure the additional cooler should be an issue?
Ok so new radiator is installed with new lower hose old hose wasn't bad but it looked like it could be a PITA so now was the time.
I started it up let it get up to 210, I think that is warm but I've read it is normal temp, correct me if I'm wrong. I shut it off and let it cool. I refilled the over flow.Started it again got it up to temp and then took it for a spin, temp started to go above 210. Went home. I parked it and popped the hood. The upper hose was hot and I cracked the rad cap and the coolant was stone cold. The lower hose was cold too. only the very upper most part of the rad was hot even that wasn't too hot to touch. Heater was blowing hot and the heater core hose were both hot.
So as I finish this novel I hope she has sucked down more coolant from the over flow. That's my story, there is more I'm sure but this should get us going.
So besides air since I get heat and the upper hose gets hot what to look for. It would be a big coincidence for two things to go at once but hey, who am I to say.
Also what should normal temp be on the gauge?
Thanks in advance
