Move cooling air with a plan
A rear-deck aluminum radiator shroud can move a radiator away from the worst front-end mud spray. Placement still needs a clean air path, protection from debris, service access and secure mounts. Long coolant runs must be supported and protected from abrasion, heat and trapped air.
SPAL waterproof brushless fans are one option where the chosen model’s airflow, electrical requirements and environmental ratings fit the installation. Fan control, fuse sizing, charging capacity and a way to monitor coolant temperature belong in the plan.
Give housings room to breathe
Axle housings warm and cool as they work. Extended bellows breathers and properly routed vent lines can help manage pressure while keeping vent openings high and protected. Avoid kinks and blocked ends; inspect lines and fluids after water exposure. A raised vent is not a guarantee against water entry.
Seal the electrical details
Use appropriate sealed connectors, strain relief and abrasion protection. Dielectric grease can help protect connector seals and surrounding surfaces when applied according to the connector maker’s directions; it does not repair a damaged seal or replace a sound electrical connection.
Respect the depth
A 48-inch mud hole can hide abrupt changes in depth and bottom conditions. Air intakes and CVT breathing systems need routes suited to the particular machine, and no snorkel makes every crossing safe. Walk or assess the line where safe, protect the intake and shut down if water intrusion is suspected.
