Toyota Surf Conversion - BKD TDI Cooling Problems
Dear Forum,
This is my first post. I have inherited a 94' Toyota Surf with a VW 2.0 BKD TDI 2004 engine. It has been troublesome since I got it. Leaky radiator has been replaced but I'm still having trouble with the cooling system.
Basically after a drive the cooling system gets air in it and expands into the aftermarket overflow container I have fitted that comes off a pipe fitted to the 13 PSI radiator cap. It has the VW plastic reservoir also, I fill this up but after a drive it is empty. The coolant going into the VW reservoir is foamy and bubbly. The exhaust is a bit grey steamy. And sometimes there is steam / smoke coming off the erg cooler.
This made me think it was the ERG cooler and hopefully not the head gasket. So yesterday I bypassed the ERG cooler by sending the incoming coolant passed the ERG cooler and straight into the VW reservoir and snap-tied the control cable going into the valve on the ERG cooler. However the same problems again occurred. I thought maybe it just was a air bubble. So will try again today.
I'm considering ERG delete. But want to positively identify the problem first. The fact that it was smoking means there is something wrong with it fore sure, but is it the only faulty part......
What pressure does the cooling system usually run at? I know that VW usually seal their radiators, well I have a toyota radiator..
I'm curious for thoughts friends! Thanks!
