So my 87 carb'd GL has had cooling system issues since I got it. Due to an old clogged radiator.
couple weeks ago I broke some of the fins on that old radiator and it started leaking. This was my GL's first cooling system leak.
Got around to replacing the radiator while on a trip in Pennsylvania. I noticed along the drive that when the system was topped up with coolant I would have James Bond types of smoke (steam) clouds coming out of the back of the car on the highway. That's no good, so I replaced the radiator while I was there.
Problem solved right? No. On the drive back to Jersey I still had occasional giant clouds of smoke out the back of the car on the highway. WTF right?
Car stayed cool on the highway, got hot on local roads. Got the car home, haven't touched it in a week till now.
Dug in and found that one of the bypass hoses had ruptured. It was leaking coolant on to the intake manifold and it would pool and eventually spill over right on to the exhaust. There's my steam out the back of the car.
Documenting this for anybody searching issues like that. Steam out the back of your car and you're sure your headgaskets are okay? Chances are it's one of the small bypass hoses.
The one that ruptured was the one coming from the thermostat housing. I've got replacement hoses for that particular hose, as well as another bypass hose that runs from above the water pump and wraps back and down just behind the driver's side of the Craptachi. I'm also replacing that small 90 * hose that comes from the top of the water-pump as well.
I do have a question though; considering I have my air-box off and all these vacuum lines exposed, I've been trying to find GD's guide on what I can get rid of and cap off.
Can anybody help me out there? It's just the stock Hitachi on an EA82.
Thanks in advance.
I HATE cooling system problems. Ugh.
