Dougal667 Posted November 30, 2010 Share Posted November 30, 2010 Hullo all. I've a T plated Discovery Td5. None air-con model. When sitting in traffic the heater blows cold air, once you're off and running again it get's back to normal and blasts what ever temp you set the dial to from cold to hot. Just wondered if anyone has the same problem and what can be done about it. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
dooroy Posted December 1, 2010 Share Posted December 1, 2010 I have a 2001 Td5 with air con /climate control but I have noticed the same thing from time to time - cold air when idling, even though the engine is warm . I find that if I bring the revs up to about 1000 the heater works fine . Would seem to be that on tick over the coolant is not circulating as well as it should - but have not done anything about it . Been that way since I got it about 3 yrs ago . Quote Link to comment Share on other sites More sharing options...

ally Posted December 17, 2010 Share Posted December 17, 2010 Dougal, check your coolant level, td5s are sensitive to a low coolant level. i had same problem last year , perished hose so was leaking a bit. Ally Quote Link to comment Share on other sites More sharing options...
