Egr Cooler, Coolent Banjo
 

Hey all,

First of, thanks for all the help thus far. Got the old supra back up and running after replacing the problem rod bearing. Runs like a top, no CEL!.

As for my problem, I seem to be loosing coolent out the rear of the engine. I've narrowed it down to either the EGR cooler cover, or the Banjo fitting that splits the coolent at the rear of the engine. Shit is cramped back there and I cant tell for sure where its comming from. I replaced the egr cooler gasket, cleaned the faces real well AND used silicon. I also tightened the banjo fitting real well with fresh gaskets. I can say for sure that the hoses & clamps are fine, Ive re-evaluated them and tightened them.

The leak isn't hudge, or at least it didn't seem hudge when the engine was up to temp, perhaps it will be more of a torrent when I start it cold.....

Has anyone got any good ideas regarding tightining the EGR cover while the head is on and engine in the car? Perhaps some special tool or method. Can it even be done?

Thanks for any help,

Cheers,

Colin Slade

all but the bottom ones
mirror and a small box end wrench . i learned the hard way on that cover myself .

piping behind block
 

Did you check the piping behind the block? One side is the heater hose and the opposite side is the rubber plug that gets overlooked. The engineers designed the piping to work on LHD or RHD cars so you only have to switch the rubber plug and heater hose around depending on the config of the car.

There is NO coolant in the EGR cooler ! Only EGR gasses. So.........it NOT that !

Hoses or hose fitting is the likely problem. Hope it not the headgasket.

Well that certainly narrows the search down. It seemed like the top of the EGR cooler gasket was wet, but if no coolant passes within that cover, I guess I can narrow the problem down to the coolent banjo at the rear of the head.

Can anyone confirm?

Thanks,

Check the coolant hose right behind the rear of the spark plug galley.

There's another coolant hose that runs to the back side of the block right around the starter.

Hope this helps.

I had problems with that hose to the rear of the engine.
It snapped.
Looking to it from above, didn`t looked broke. I even tryed to tide up the clamp there, but no result.
I eventually took it out of there and it was all coocked up. It broke to pieces when coming out of the engine in 100 pieces.
Just replace it with any hose designed for the coolant system.
Cheap and easy fix.
Good luck.
