Hello,

The one liter SAE5W30 that I've added is leaking direclty on the ground on the right side just above the exhaust tube!
Any idea where to look?



Thanks
pJ

Welcome to the Forum!

Check your output shaft bearings. Grab each axle near the transmission and push/pull. If they move more than about 1mm, the bearings are worn and letting the fluid out.

I've checked the wheel axle and the right is moving a little bit towards the wheel! More than 1mm according to what I've seen.

Is it this kind of kit that I would need?

Are you sure it's transmission oil and not engine oil? That last photo looks like a glob of silicone sealant to repair a hole in the side of the oil pan.

If you're sure it's coming from the transmission, then I wouldn't automatically assume it's the output shaft bearings that have failed somehow... it's far more likely that it's just the axle seals that are leaking. By the way, you didn't mention if it's an automatic or manual transmission, but in either case the axle seals ride on the stub shaft of the inner tripot joint and over time either the seal wears out or the seal wears a groove in the machined surface of the shaft and causes a leak.

The best way to pin point the source of the leak is to clean up the area with rags and perhaps some solvent and take it for a test drive. Jack it up and have another look to see where the fresh oil is coming from. If it is coming from the seal area, and you have a manual transmission, then you can follow this thread for a step by step procedure on how to remove the axle and replace the seal: www.fiero.nl/forum/Forum9/HTML/000004.html

No....the seals and bearings we are talking about are in the transmission. That e-bay kit is for the hub.

If you added 5 w 30 oil to the transmission, I hope it's a manual transmission else you're in for some future transmission problems unless you drain and refill with Dexron II transmission fluid.

Common places to look underneath for oil leaks are the oil pan to engine mating surfaces, the front pulley area which would include the timing chain cover and the crankshaft pulley seal.

Valve cover leaks can be seen from the top unless it's the cover nearest the rear window and that will have to be determined below. The cam bearing cover at the rear of the engine and the crankshaft rear seal will usually drop at the flat inspection plate on the bottom of the transmission bellhousing. The transmission input shaft seal leak will show up at the same place, but the color and texture of the oil will be clearer and cleaner. A bad distributor O-ring will show a puddle on the top of the transmission, just behind the distributor.

Transmission output shaft seals are easily seen and leaks verified since they're in clear view from the bottom.

Hello,

Thank you for your reply, this is of course a manual transmission and the transaxle fuild was completely emptly. I've added 1l engine running and it was raining but I'm not sure this is coming from the transmission!!!
I think this is too much on the right for that, what remain? Engine oil or cooling fluid? Where can I check the level of the cooling?

The second picture with the yellow stuff is something else that I saw taking pictures of the first issue, it seems to be a repair for something else.

Last information, the car was in a garage for ten years without diving!

Thx
laurent

If it's coming from the passenger end of the engine, the water pump would be suspect. There is a weep hole underneath the snout. If the bearing goes bad, it will leak from there. You'll need to turn the engine off to feel underneath for signs of coolant.

The Fiero is not like other vehicles where you can simply fill the radiator with coolant and be done with it. You must fill it from the engine at the thermostat housing cap. It's on the passenger end of the engine with what looks like a standard radiator cap.

First, carefully loosen the radiator cap to see if you get coolant coming out. If you do, tighten it and leave it alone. If not, go ahead and remove it. Fill the radiator to the top with coolant.

Next.

With engine cold, remove the cap and remove the thermostat from inside. Fill the thermostat housing until the engine and hoses are full.
Replace the cap but only tighten to the first click. Note the arrows on the cap. They should be pointing vertically and not horizontally.
Start the engine and let it run for about a minute to 2 minutes then turn off the engine.
Remove the thermostat housing cap and top off with coolant again.
Replace the cap and repeat the process by letting the car run for 1 minute.
Turn the engine off and check the coolant level again. Top off if necessary.
When full, replace the thermostat and tighten the cap until the arrows are positioned horizontally. One of them should be pointing at the big host that comes off the front of the thermostat housing.
Fill the coolant recovery tank at the front to half way between the low and full mark.

Morning Fierofool,

I suppose that I can put only water for the time being?

- Radiator cap removed, coolant coming out. I leave it alone.
- Engine cap and thermostat removed, more than 1L added. Engine and hoses are full.
- Cap replaced with arrows vertical.

Engine started for 2 minutes. Euuuh the result is raining again !!!

FieroGT88 - Video of water going out

Here is a picture of the cap, the fluid is definitively going out !



Is it normal, this white foam?

With all that corrosion, does your thermostat housing cap actually seal... or is that where the coolant is leaking from?

Here is again a small video with Fiero on rails.

Video of the coolant a few seconds after engine stopped.

Second video from the other side, looks like coming from/behind this pulley?

The origin of the Nile?

That could just be the path the water took and ran behind the crankshaft pulley. There is no water area behind it. The water pump is above it as is the thermostat cap, so any water from those would run down behind the crankshaft pulley.

The white foam in the coolant is a little worrisome. It could simply be the result of low coolant and air in the system, or it could be something more serious, like a blown head gasket. If it's available in Belgium, see if your auto parts store has a loaner or rental tool program. Get a cooling system pressure tester. Essentially it's a modified cap with a pump and gauge. Install it on your thermostat housing, pump it up to about 14 PSI and let it sit. Watch for pressure leak down and water leak origin.

Hello again,

Removed the rear right wheel and the side protection, the water is coming from or above the lower pulley. Water pump?

Video of the water leaking!

I think you have the same issue as I had.

Where the heck is this coolant leaking from?

Hello Patrick,

Will have to change the water pump? Can I drive the car to a garage or this is completely stupid?

If it's your water pump that's leaking, yes, it'll need to be replaced.

Depends how fast it's leaking and how far you need to go. You don't want to be running the engine with no coolant!

VoilĂ , the water pump has been ordered - ACDelco Part # 252613
I'm now looking for the clamp, I'll probably order the Cardone Select Part # 5513114 pump but this is not so easy to find.

I need to update the thread of mine that I previously linked to HERE, but I wanted to warn you that the ACDelco # 252613 water pump is not a good choice for an '88 Fiero. I had to take it back as the heater core pipe it has installed (which isn't required on the '88) uses a non-standard thread and I couldn't find a plug with a matching thread to put in its place. I returned the ACDelco pump and bought the Cardone # 5513114 pump instead. It came with the clamp and the plug and it works just fine.

EDIT: I've now updated my thread.
