First_Fleet Posted December 4, 2008 Share Posted December 4, 2008 They sure do when working properly. Do you have a 4 way heater valve? If so, has the rubber tube fallen off the tiny spigot? Maybe you have an air lock from refilling? Removing the viscous fan improves it, all things being equal. Quote Link to comment Share on other sites More sharing options...

First_Fleet Posted December 4, 2008 Share Posted December 4, 2008 '91. Well you won't have a viscous fan then. If you have a valve & I don't know what they had, but on my '95 V8i for instance, it's on the driver's side with the heater pipes connecting it.

I replaced the thermostat on my TDi300 recently (which was stuck open a few mm) and now even in -3 degC she is warmed up bang in the middle of the guage within a few miles and the heater really chucks out some heat. Viscous fan also fitted. I had an air block in the heater and system after refilling which required bleeding from the plug on the stat housing to cure. Seems there maybe more than one fault : 1) an air lock in the heater matrix - are the in and out feeds cold to the heater matrix ? 2) faulty gauge given a low reading even though the engine has warmed up 3) faulty stat / or rubber sealing ring Does the top rad hose start to get noticeably warm before reaching running temp ? This would indecate a stat opening too early or the rubber seal leaking. Mine stays cold until and then bang the stat opens and it gets hot. Good luck Quote Link to comment Share on other sites More sharing options...
disco_al Posted December 4, 2008 Share Posted December 4, 2008 '91. Well you won't have a viscous fan then. yes there is 200tdi's are overcooled from the start anyway. had the same problem on my old one last year - best advice is to remove the viscous fan altogether, it's not really needed this time of year anyway. the other option is to use some gaffa tape across the grille (mask off the rad only though - not the cooler) blocking the cold air flow to the rad, this helped mine a bit. never got round to removing the fan, sold it and got a v8 instead, nice and toasty now Quote Link to comment Share on other sites More sharing options...
