I have a 62 with a 5.3 vortec. It seems to dislike water. If I run through a stream, deep puddles, or the undercar blast at the car wash, the motor struggles and or dies. Seems water may be getting in something somewhere? If I'm able to keep driving she'll finally swallow/spit and catch her breath. If she does actually die then she'll eventually come back but I've always been able to let her dry out. The concern is obviously at a long crossing and her dying in the water and not being able to catch her breath. So I guess my question is where would the water be getting in and has anyone had a similar problem and if so what was done to remedy?
