Takes ages to warm up

simondhopkins · 19th May 2017, 22:17

Just had a thought, over the winter period, my cdti took ages to warm up (no fbh) is this normal?

Search for the in-line thermostat modification, it will help a lot.

Define ages?

Mine takes about eight miles to get up to correct running temp

well takes me 15 minutes to get to work on 30mph roads, and temp gauge not even between the bottom and first line.

Will have a look at the thermostat mod thanks.

As with Rooney, my thermostat is working perfectly but still is around 5 or 6 miles in winter to get warm. These engines do run very cool at the best of times, I am sure I read about a 95 degree thermostat but I don't think that would increase warm up time.

This may be what you are after, mine did the same when I first got it and would never warm up.

Quite a quick job.

The most important thing with the in-line stat mod, is to buy the right brand. Some stats either have a bleed hole in them or they actually leak slightly around the closed valve. Any bleed through of coolant will reduce the running temperaure significantly.

Known bleed-proof models are those branded FirstLine, Gates and Wahler. There are no doubt others, but they haven't been identified thus far. Go for the highest rated available (89C I believe).

Is it a 2- or a 3-speed? The 2-speed system will just need a replacement slow speed resistor. These are readily available from forum traders, eBay or electronics outlets (Farnell, etc). A 3-speed fix is more complex, but fully documented on the forum.

Its a 3 speed 4 brush motor. Will just be replacing the brushes and know they're stuffed.
