b4u2 Posted December 6, 2021 Share Posted December 6, 2021 That sounds very interesting, have you taken it to a garage to get it checked? Quote Link to comment Share on other sites More sharing options...
Baz Posted December 9, 2021 Share Posted December 9, 2021 the Matrix will have to pipes inlet/outlet if you can feel the inlet when engine is hot then the outlet and they are not both the same temperature the Matrix is blocked and needs to be replaced or cleaned out as the pipes in the core block up and restrict the flow 1 Quote Link to comment Share on other sites More sharing options...
