Coolant temp sensor

Reet i huv searched through the threads and cant find owt if there is any way to identify coolant temp sensor differences between 19j and 200 tdi.
My situation is this, Temp gauge reads at right hand side of white bit just before the red when engine is up to temp, So i want to find out if i perhaps have the wrong sensor bur right gauge or vice versa becaus i THINK i might have either a late built 19j with a 200tdi conversion with 19j gauge or a 200tdi gauge wi 19j sensor. hope this is clear

Well based on the age of your landy you should be able to work out which engine it would have had. If its had an engine change from a 19J to a 200 then I would expect that the guage is still a 19J guage in which case you need to find the PRC3359 (may be marked green somehow) guage.

However having said that, the guage aforementioned is the same for the 2.5TD/200/300 & 3.5V8. So maybe you need the PRC3505 sender which is in a housing and in some may may be marked yellow.
