martywarner Posted November 2, 2008 Share Posted November 2, 2008 So in a long line of cooling questions and problems here it is. Coming home from a friends place the other night on the 401 running right at 100kmh i noticed the truck start to heat up! did not get to hot so was nt too worried. then when i pulled into the drive way and shut the truck off i could hear it bubling away hmmmmmmmm. took the truck out today did not mak it 4 blocks and the temp gauge was maxed SOB so i looked under the hood and realized i know sfa about open cooling systems. so with the information could you guys please help me figure out what the issue is hear? thanks ooooooo and another thin is i barely have heat like not enough to defrost the windows in the winter and even when the truck was overheating it was still not hot? please help winter is hear and its cold. oh byt he way it is a 89 eliminator 2wd 4.0 5speed. thanks guys marty :Canadaflag: Link to comment Share on other sites More sharing options...
mvusse Posted November 2, 2008 Share Posted November 2, 2008 Hey, I know the 401! Then again, my parents live in Canada and I went to college in Waterloo (UofW). But I will not believe you were going any slower than 120... :D Anyway, sounds like either a clogged system (both radiator and heater core), a stuck thermostat or a bad water pump. Try running without a thermostat, to see if you still overheat. If so, take the truck to a radiator shop and have them flow test the radiator. You didn't by any chance use tap water instead of distilled, did you? I plugged up 3 radiators with rust gunk from iron in the water before I learned my lesson.

Eagle Posted November 2, 2008 Share Posted November 2, 2008 Um ... your signature says you have an 87 and an 89, but your post is asking about an open cooling system. Have you converted, or do you have the terminology mixed up? Link to comment Share on other sites More sharing options...
mvusse Posted November 2, 2008 Share Posted November 2, 2008 It is also possible something failed not letting the system pressurize (cap?), causing the coolant to boil at 212 degrees, and causing the overheating and little or no heat in cabin from not enough coolant left.

BLHTAZ Posted November 2, 2008 Share Posted November 2, 2008 Um ... your signature says you have an 87 and an 89, but your post is asking about an open cooling system. Have you converted, or do you have the terminology mixed up?That's what I was wondering too. You should have a closed system on yours unless it's been converted as Eagle asked. Try the t-stat first as that is the easiest and a fairly common problem. Link to comment Share on other sites More sharing options...
Redramman Posted November 3, 2008 Share Posted November 3, 2008 Could be air in cooling system ,low coolant. Link to comment Share on other sites More sharing options...
pingpong Posted November 3, 2008 Share Posted November 3, 2008 The closed system requires periodic monitoring. You have to regularly check the fitting and hoses. A slight pressure leak, and the system can fail easily. Link to comment Share on other sites More sharing options...
martywarner Posted November 4, 2008 Author Share Posted November 4, 2008 sorry guys just got in off the highway. the truck is the 89 i forgot to change my signature. so it has the stock closed system my bad its the stupid one with the bottle up by the fender i refilled the system tonight and it seems to work fine the 4 miles i drove it home. however the $#!& that is coming up through the bottle is a gross brownish green colour. the water pump seeems to work fine as it moved the coolant as i filled it. gpoing to take it out for a good tour and see what it does would it be n m interest to take it to a shop and get the system flushed? thanks marty :Canadaflag: Link to comment Share on other sites More sharing options...
martywarner Posted November 4, 2008 Author Share Posted November 4, 2008 ah and there is some seepage on the pass sie of the motor between the head and block Link to comment Share on other sites More sharing options...
maddzz1 Posted November 4, 2008 Share Posted November 4, 2008 It sounds like there is rust in your system from somewhere. If you are not comfortable flushing the system yourself than I think you should bring it somewhere and have it done. For the $7, I would replace the thermostat when it is done too; I would get one that is 195* Just saw your second post. A pressure test would be a good idea. Are you sure it isnt just antifreeze that settled there when it overheated? your sure it is coming out between the head and block? Link to comment Share on other sites More sharing options...
martywarner Posted November 4, 2008 Author Share Posted November 4, 2008 not sure how long seepage has been there. as far as pressure test are you saying cyl leakdown or coolant system check? i did the t stat in jan and put a 195 in Link to comment Share on other sites More sharing options...
mvusse Posted November 4, 2008 Share Posted November 4, 2008 X2 on the rust. At some point in the past tap water must have been used instead of distilled. And that rust is REALLY good at plugging up radiators and heater cores. Link to comment Share on other sites More sharing options...

It will let you know if the system is staying pressurized. I believe if the head gasket is blown it won't hold pressure. Someone correct me if I'm wrong I would replace the thermostat again after the flush. If there is rust in the system it could clog the thermo and not allow it to function properly Link to comment Share on other sites More sharing options...
Oizarod115 Posted November 4, 2008 Share Posted November 4, 2008 a little bit of seepage from a head gasket won't kill you but it should be monitored. just keep an eye on that, as long as its not getting in the engine or the oil you shuold be alright until it starts leaking bad enough to matter. as long as its not dropping the amount in the bottle every day. but you should probably have someone flush it well, and a pressure test isn't a bad idea on the cap and the whole system too. if you feel like doing it yourself you can blow compressed air through the heater core to loosen up stuff or run water through it.

martywarner Posted November 4, 2008 Author Share Posted November 4, 2008 well took it to a rad shop an they tested for the pressene of combustion chamber gasses in the coolant and bingo headgasket gone. anyone want to buy an 89 2wd with blown headgasket.

mvusse Posted November 4, 2008 Share Posted November 4, 2008 Head gasket is not terribly hard to replace. If you are getting rid of it and can't sell it whole, any chance you'd consider selling the rear axle? ;) Link to comment Share on other sites More sharing options...

Kenosha Warrior Posted November 5, 2008 Share Posted November 5, 2008 Marty, the headgasket isnt such a pain to change. Pop onto Jeepkings and see if anyone in the area will give you a hand. I remember your posts from when you originally got the truck and you were in love with it, don't let it go like a bad ex, these jeeps stick by you thru thick and thin.

pingpong Posted November 5, 2008 Share Posted November 5, 2008 Not sure of the price difference from Canada to the U.S., but a head gasket set here is 75 bucks. Bascially you will need a set of good hand tools, a deep well 16mm as well as a torque wrench. I find it easier to thread to ste of bolts in the head a run a length of chain to make hand holds to set it in place.
