Right,ran engine up to temp. 98 degrees at idle - increased rpm to 2500rpm and held it at that rpm for few minutes coolant temp dropped initially to 90 degrees then slowly crept back up to 97 degrees. On returning to idle speed coolant temp rose to 102 degrees briefly then settled back to 99degrees.
Had a play with heater temp settings from different vent outlets after doing the above. With heater set to just footwell vents compared temp of drivers side to passenger side - with both set at same temp 25c drivers side did feel slightly warmer than passenger side but not too much different and neither felt as hot as they should set at that temp. Lowered temp setting of drivers side to LOW and temp from that drivers side footwell vent did indeed change to LOW while Passenger side one stayed WARM. Returned drivers side temp setting to 25c and lowered passenger side temp setting to LOW and this time passenger side vent output changed to LOW while drivers side stayed WARM. Did same test through dash vents and then through the defrost vents with same results,side with temp set at LOW resulted in much cooler air from that side while opposite side stayed WARM. So guess most of the flaps inside are working ok but maybe just the one/ones that control how much heat flows through heater matrix into heater box is/aren't working properly ? |

I have never been able to roast my feet in the 75. Have you checked the actual temperature in the car?

Seeing you have had the coolant temperature through the matrix very hot there can really be only one fault. Too much cold air is being introduced from the outside.
Probably find the internal flaps jamming on a bunch of dead leaves.--- PS. Or a mouse nest. |

If an internal flap is jammed on dead leaves or a mouse nest maybe I should send in a trained mouse to remove said leaves or nest as i've heard gaining access to the flaps inside heater unit can be a pain of a job !

Thanks for your reply. Believe it or not, you won't necessarily see coolant leaking out if your fan is able to limit the temperature reasonably well. What you should be seeing is a temperature of between 92 & 95 degrees on the move (from memory that's what I get) rising slowly to 100 if you're stationary or manoeuvring afterwards. I'd suggest that you inspect the expansion tank cap O ring seals. Do they look flat? Mine were after about eighteen years! Simon
