Went to drain the coolant in my ,87 SDL last night and found that there was no drain on the lower Radiator housing. I mean none, not even a bolt or bushing.
The rad. is a replacement OE Behr that was installed by the PO in 2000.
I had to remove the lower Rad. Hose to drain the coolant - very messy
The manual shows a drain plug but it definitely wasn't there on mine.
Has anybody else come across this
