TheFish Posted October 19, 2015 Report Share Posted October 19, 2015 After much internet searching, I can't specifically find where the thermostat is? Has anyone changed one? How complex is it? I assume the rad has a temp sensor, then the actual thermostat is anywhere really....My thermostat takes a good 15-20 mins to get to 90, but it also goes up and down a bit first....once at 90 it's fine. Just seems odd behaviour as have had a few tdis but never had this, so if an easy job, I will just do it as part of ongoing mid life refurb work.....it's an 02 with 76k....Any pointers?

Sausage Posted October 19, 2015 Report Share Posted October 19, 2015 (edited) you didnt search very hard then did you to be fair there isnt much lupo stuff out there, i end up using polo mk3 or skoda fabia manuals.http://workshop-manuals.com/skoda/fabia-mk1/power_unit/1.4/51;_55;_59_kw_tdi_pd_engine/engine_cooling/cooling_system/removing_and_installing_coolant_regulator/Reasonably sure lupo will be similar.

Rich Posted October 20, 2015 Report Share Posted October 20, 2015 You need to take the alternator off. . .. . 1 Quote Link to comment Share on other sites More sharing options...
Dblock Posted October 20, 2015 Report Share Posted October 20, 2015 That's sure a hard way of doing it. Quote Link to comment Share on other sites More sharing options...
Rich Posted October 20, 2015 Report Share Posted October 20, 2015 There's an easier way? Quote Link to comment Share on other sites More sharing options...
jon_273 Posted October 20, 2015 Report Share Posted October 20, 2015 Yes, use a knuckle joint on the socket. Mine has A/C, but if anything I would have thought that would make changing the thermostat even harder as there are more things in the way. 1 Quote Link to comment Share on other sites More sharing options...
jon_273 Posted October 20, 2015 Report Share Posted October 20, 2015 This is my car. Maybe it's different because of the a/c but I changed the thermostat without removing the alternator. And it was a waste of time anyway, it didn't make it warm up any faster! Quote Link to comment Share on other sites More sharing options...
