lascoflats Posted August 28, 2013 Share Posted August 28, 2013 Hello, I have a 93 Subaru Loyale with an 86 EA82T engine. First off my mother was driving it home from the muffler shop to get an estimate on parts to fix a hole in my exhaust. On the way back the car broke down and turned out that the timing belt broke. So my father and I replaced the timing belt and since we went that far we replaced the water pump. And a few hoses that were a bit worn. Then we start it up again and when driving it, it won't accelerate and overheats quickly. So we replace the thermostat and a hose running from the thermostat. Same problem persists. So just today I went ahead and did a radiator cleaning and then drained it and put in some Blue Devil sealant with antifreeze. I did all of this following the instructions. The problem still persists. I know it's possible that the Blue Devil sealant could not of worked or the head gasket could not be the problem. I am running out of ideas and need some serious help. Hours of work trying to get this back into working order. P.S. It idles without overheating, I burped the engine to remove all air, with all the times I drained the radiator. Hope to get some replies on this issue. Thanks and have a wonderful day! Quote Link to comment Share on other sites More sharing options...
MilesFox Posted August 28, 2013 Share Posted August 28, 2013 (edited) Is the timing belt mounted correctly? using the proper marks? maybe you have a tooth off. Try adding coolant to block from the upper radiator hose. Remove the thermostat and fill the block there. Bleeding the air out is tricky with these. Run the heater on full hot. You should get hot heat.If the heat is cool, there is not enough coolant in the system. Edited August 28, 2013 by MilesFox Quote Link to comment Share on other sites More sharing options...
lascoflats Posted August 28, 2013 Author Share Posted August 28, 2013 Yeah the heater works. I have ran the heater every time I have ran the car, the entire time. Blows hot never gets cool. Going to go ahead and take down the car to the timing belt and see if we did something wrong. One problem is that when my dad and I changed out the timing belt we thought the engine was a 93. I bought the car from the second owner and the first owner was an engineer. He changed out the engine and I did not know this when buying the car and I imagine the guy I bought it from didn't either. Or did and didn't want to deal with a car that has been modified like this. So the possible problem could be that the timing belt was not put on to specs. Thanks for the response. I will repost with any changes. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted August 28, 2013 Share Posted August 28, 2013 No difference in how the timing belts are mounted and aligned in any of the EA82 engines.. As MilesFox typed, good chance the belts are not aligned properly. You have a turbo engine installed in a car that die not originally have a turbo engine? Some clarification might be useful. Is the radiator fan coming on when it gets hot? Does this engine have the engine driven cooling fan on the engine's left side? If you can safely put your hand on the radiator's fins, do so and check for temperature differences/bands top to bottom. Did you mess with the ignition timing?

lascoflats Posted August 28, 2013 Author Share Posted August 28, 2013 (edited) He didn't mention that at all. From what I understand, he just stated the timing belt might have a tooth off. The timing belt might've not been installed correctly cause we followed instructions for a 1993 engine. When in fact the engine is a 86 EA82T engine. And I stated in my first post this: "I have a 93 Subaru Loyale with an 86 EA82T engine." Both fans both work properly. No I did not mess with the ignition timing.

bratman18 Posted August 28, 2013 Share Posted August 28, 2013 (edited) And as said before, there is no difference in how the timing belts are put on between any EA82 engine whether turbo or not, or what year it is. If the belts are not aligned correctly, or as he put it, "off a tooth", then it could cause the lack of power and the overheating issue.

lascoflats Posted August 28, 2013 Author Share Posted August 28, 2013 (edited) Ok so we followed these instructions... If I am not mistaken. This is Milesfox that posted the first response. I did some work with this install. But my dad did the bulk of putting it on cause he use to be a mechanic. Thanks again!

lascoflats Posted August 28, 2013 Author Share Posted August 28, 2013 (edited) Sorry for my limited knowledge. This is the first Subaru I have ever owned. My previous car was a Suzuki Samurai, and did a lot of work on it. Edited August 28, 2013 by lascoflats Quote Link to comment Share on other sites More sharing options...
MilesFox Posted August 28, 2013 Share Posted August 28, 2013 An ea82t should have a dual row radiator. Make sure that the rdiator is not corroded or missing fins. Check that the thermoswithc is connected on the bottom side of the radiator. You can test the fan by jumpering this terminal to see if the fan is working or not. Yup, the video is the one i put up. If you followed the instructions correctly, you got ot. Although it is possible to be a tooth off. For clarity, are you sure we don't have an 86 turbo with a 93 loyale engine block? A turbo block has 7.7:1 compression, a carb engine has 9.0, and spfi has 9.5 Please elaborate more on the history of the car. Quote Link to comment Share on other sites More sharing options...
lascoflats Posted August 28, 2013 Author Share Posted August 28, 2013 Well I don't know a whole lot since I am the third owner and the first owner is the one that put the 86 EA82T engine in it. Yes it is a 93 with a 86 EA82T block in it. It is not a stock 93 motor. The 93 motor was taken out to put a 86 EA82T engine in it. I found a hand written wiring diagram and a list of instructions of things he did to the car. Also stating on the wiring diagram that the engine is a 1986 EA82T engine all in the glove box. Did not know this when I bought the car. Sorry that is all I know about the car. The guy I bought it from didn't say anything about a engine swap. I did not know when purchasing this car about 93's not having turbos. Ok I will check the rest of what you have said. Thanks for the response.

MilesFox Posted August 29, 2013 Share Posted August 29, 2013 He must have swapped in the whole harness from the 86. either that or chopped in a standalone wiring harness. If he successfully swapped a whole ea82t and harness, he must have know what he was doing. The loyale would have had a single core radiator originally. The timing should be set to 25 deg BTDC for 85/86 mpfi turbo. It should have a mechanical disty and an external knock control unit in the passenger side fender, and a vane style (flapper) Mass Air Flow sensor. Can you provide some pis of the engine and harnesses? Do you know if the car has the correct thermostat? A lot of the aftermarket thermostats have a smaller brass valve and lack the little jiggle ball. This could be a problem with overheat as well.

lascoflats Posted August 29, 2013 Author Share Posted August 29, 2013 Thanks again for the response. I can get you some pictures tomorrow of the engine. Getting dark here. I am going to try to run the engine without a thermostat to see if that works better. I could have bought a thermostat for a 93 engine rather than the 86. If that's an issue.

MilesFox Posted August 29, 2013 Share Posted August 29, 2013 Not an issue in that regard, but an issue depending on the brand or parts counter you got it at. You can get the right ones aftermarket, but you have to stay away from the economy brands. A chevy small block thermo fits, but the brass piece is not the same as for subaru.

scoobiedubie Posted August 29, 2013 Share Posted August 29, 2013 The hole in your exhaust will cause a lack of power because you don't have the same amount of exhaust spining your turbo to compress intake air. Bad plugs, bad plug wire connectors, corroded distributor cap points, leak in your intake between the turbo and the intake manifold, and timing belt off a notch will all also cause loss of power. Over heating can be caused by bad radiator thermostat that triggers auxiliary fan, running the headlights, high humidity, worn out water pump, clogged radiator, pulling a trailer, carrying something on the roof, and loose cylinder head bolts that also shows up as coolant blowing out the overflow bottle and a deposit on the radiator cap. No subaru came standard with a double core radiator that I am aware. But a turbo certainly needs one. Quote Link to comment Share on other sites More sharing options...
leniac Posted August 29, 2013 Share Posted August 29, 2013 are you sure that the water pump is the correct water pump for the ea82t? Quote Link to comment Share on other sites More sharing options...
MilesFox Posted August 29, 2013 Share Posted August 29, 2013 are you sure that the water pump is the correct water pump for the ea82t? The only difference in ea82 water pumps is the shaft lenght depending on the pulley. The turbo should have a short water pump with a bolt-on pulley. And to scoobiedoobie, a lot of of not all the ea81 radiators are double row, and the ea82t came with them standard, and are retrofittable to single cores as well Quote Link to comment Share on other sites More sharing options...

You can get the right ones aftermarket, but you have to stay away from the economy brands. A chevy small block thermo fits, but the brass piece is not the same as for subaru. Oh it was overheating with the old one in there, it over heats without one in there. We just replaced it to troubleshoot the problem. The old one was fine. So I am pretty sure that isn't the problem. The hole in your exhaust will cause a lack of power because you don't have the same amount of exhaust spining your turbo to compress intake air. Bad plugs, bad plug wire connectors, corroded distributor cap points, leak in your intake between the turbo and the intake manifold, and timing belt off a notch will all also cause loss of power.

No subaru came standard with a double core radiator that I am aware. But a turbo certainly needs one. I know the exhaust leak can cause lose of power. That I know isn't the issue cause I had the exhaust leak before the timing belts broke on the car. It is not driving the same as it did even then. Radiator all of that not clogged. Flushed the radiator probably about 5 times now. are you sure that the water pump is the correct water pump for the ea82t? I went through three different water pumps until it looked like the one that it was in their before. Had to order all of them off the internet. So yes I am sure. The other difference is the blades. Finally got a new timing belt today to borrow. Going to work with it today. Quote Link to comment Share on other sites More sharing options...
lascoflats Posted September 4, 2013 Author Share Posted September 4, 2013 @Milesfox My dad thinks after installing the timing belts, it is 180degrees off. He is Wondering if you would possibly know what he might've done wrong. Thanks. Quote Link to comment Share on other sites More sharing options...
