Silverspaceship Posted August 19, 2019 Report Share Posted August 19, 2019 Hello all, I need some help,( my wife has been saying this for years). I recently bought a 2.8 diesel grand voyager automatic, 05 plate. My problem is that the temp gauge rises when I go up hill and accelerate to maintain speed. I have read a post from 2015 about this issue occurring when towing uphill. The suggestion was radiator replacement. Had this issue ever been solved with flushing the system/rad or is replacement the only solution? Thanks in advance. Tony Quote Link to comment Share on other sites More sharing options...
