2.5 V6 heater problem hot>cold>hot
Hi,
On the V6 Rover 75, the heater has started going cold, and on investigation it appears (could be coincidence) that when accelerating it warms up, and at times gets nice and hot for a time before going cold again. Initially I thought perhaps a stuck thermostat but doing the diagnostic shows and engine temperature as I was test driving around local roads around 100 degrees, certainly plenty for a toasty heater. Coolant level is fine Thanks in advance |

You have an airlock in the system, have a search on here for the correct procedure for refilling the system, this should sort your issue.

Would that be likely despite the car not having had any work done since buying it last week? (when the heaters were fine)

Yes, if it hasn’t been done correctly then it will keep happening until resolved I’m afraid.

Coolant level is same as it was on picking up the car.
Would air only get in with a leak ? |

No! The coolant level will remain the same with an airlock, the coolant won’t be circulating around the whole system properly. Sent from my iPhone using Tapatalk

On a side note, It’s a 02 reg, and I think a 3 speed fan as no visible relay, but no fan kick in until coolant reaches 112 on the diagnostics on IPK.
Fan works with AC What would this indicate? |

Sounds like your low speed is dead too, this needs sorting as it could lead to other issues if left.

David, your profile says that you have a 1.8T engine but you are definitely asking about a KV6? Please confirm. By the way, it's not a relay it's a resistor.
