Thread: pink/red fluid passenger side coolant leak ?? D2 v8 manual

It just looks like the throttle housing preheat chamber is leaking - it could just be the gasket but it may be the housing itself with that much coolant leaking out.

thanks for the reply scott - the coolant has been adding up there since about eghem... Feb ... !!!

if it is a gasket ... do you know if replacing this is detailed in the RAVE CD? Also, are the gaskets easily sourced?

If it is the housing though - how would one tell?

appreciate your help or anyone elses...

Thanks,

I would budget for a housing. It's only about $50, maybe less if you shop around. Part # MGM000010K.

RAVE would have the process but I'm sure it's just a matter of lifting the top of the plenum off to access the housing.
You might even be able to just remove the throttle assy to get to it - I haven't worked on that type of engine, just the earlier ones.

Hi - thanks very much for that, really appreciated :-) Will go and hunt down the parts...

cheers,

You can bypass the throttle housing altogether if you are not concerned about it freezing up. I doubt it gets cold enough in Frankston to be a concern but if you go to the high country in winter it may be.

Buy a gasket and pull it apart. If the housing needs replacement, bypass it and drive it like that until you can get a new housing. It isn't a huge job just a bit fiddly with the throttle cables, TPS, engine breather and coolant lines.
I had to move the AC compressor to access the coolant line when I bypassed mine.

Its those smelly diesels that have fuel coolers,,

That leak is very common by the way,,

did you read this?

I have run my RRC with a Thor fitted for 5years+ now without the throttle warmer connected with no freezing.
AFAIK they are only necessary in zero temps and very high humidity ie snowing/sleet. Remember that we are not talking a carb here with the evaporation of fuel causing temp drop and icing , just the temp drop of expansion of air past the throttle blade.
Although in Frankston you never know.

Replaced mine just a few weeks ago, remove the hoses connected to the throttle body, undo the air intake and undo the 4 bolts (6mm I think) being careful not to lose the gasket. The 4 bolts holding the plate onto the throttle body are an unusual size, 5.5mm, remove the little plate with the inlet & outlet for the water to circulate underneath. My gasket was cardboard like so I just replaced the whole thing, gasket & plate come in a kit & I was told you can't purchase them separately. I put a small amount of black gasket goo on as well just to make sure.
Note- if the engine is still warm, undo the header tank to release the pressure in the cooling system and I also clamped off the two lines running to the throttle body to minimize coolant loss.
Hope I've been clear enough
