Break down Description: Coolant leak.
Symptoms: None - Green coolant all over everything
Effect: Stranded until fixed
Cause: Plastic sight glass in reciever tank blown out
Remedy: Installed plug in hole
On first trip, decided to stop at roadside vegetable market on way to Cape Hatteras NC. After stopping and as I was doing a walkaround check, found coolant all over toad and engine compartment. Found the "PLASTIC" sight glass on the coolant reciever tank was blown out. After much searching of auto parts and hardware stores within 20 miles was able to get a tap large enough and a brass pipe plug and tap out and plug the hole. The site glass is threaded in but is a bastard thread and could not find anything that would fit it. Now I must take the cap off and stick my finger in to check coolant level BEFORE engine gets hot, or wait till it cools down as the reciever tank is mounted too high to see into.
