Engine CHT Climbs While On Ground at Idle
in General Tech Discussion

Help! I have always had issues with cooling (CHT only, never oil). But it seems like it is worse now than ever. Once I take off and start flying I can manage it, but it is a constant battle. It makes no sense to me that the engine CHT is getting out of hand while idling on the ground. I have the new style radiator cap (1.2 bar) that is now at least 200 hours old. I run DexCool 50/50 mix. I have always had to watch temps on the ground but it is getting out of hand. Once I am flying and I have some air flowing over the engine it is ok. We have had cooler temps lately and nothing is adding up.
Also worth noting, there is no kind of pressure cowling or "ducting" around the heads to direct air over the cyls. I am running a 2 blade propeller.
My first thought is the water pump, but the engine only has 366 hours on it.
Thoughts? Thanks in advance.
