Vacuum leak - ZR-1 Net Registry Forums

Sorry to hear of your predicament.

I didn't even know the oil cooler has a drain plug. Are the drain plugs on 90 - 92 model year coolers only? I had my oil cooler out and flushed it out with mineral spirit but didn't notice any plug.

Ebay has a used 90-92 oil cooler plus AC condenser for sale.

Also, a new one but listed as for 93-95 ZR-1.

Does anyone know what the difference is? If it's just bolt hole location, I would buy a new one for later years and modify as needed.
