| The Defender 90 can take on a lot of water and still keep on going, The gauges are splash proof and most electronics are sealed up good from the factory. Though I never recommend to go deeper than the factory specified 18 inches of fording depth. ( I only lost the AM /FM radio on this big water hole) |  |
| I use "dielectric grease" (It can be bought at any automotive store) on all the connector plugs and all relay connections | |
| All of the breather tubes for the diff's and transmission go to a central location. | |
| I also removed the masking tape in the battery compartment and bought some 1 inch "knockout" plugs and silicone them in place. ( I removed the dynomat that I installed in the compartment and the sticky residue is still there.) | |
The connector for the 4 ignition coils on our 97 always gave us problems so I installed shrink tubing and silicone to prevent water from getting in. This connector if wet will cause a miss-fire and the check engine light would come on even after going through a drive through car wash. The white color is the shrink tubing near the throttle cable. |
