I would move them, at least up to the cowl by the wipers... Can't hurt, especially with how they are tied in to the motors ECM. I swear these manufacturers do this stuff on purpose, as no one could be that stupid. Counting the dollars in the shop, that they are.

Yup and they don't care because they design everything to be a headache. Looks like I got myself something to do tomorrow

I thought there used to be a post on here of where that sensor was located. I posted where mine was, 09 Prostar, mine wasn't buried in tape like yours, and I find mine reads fine unless I'm stopped. If it's on the highway getting lots of air it reads correctly.

I know I have asked at least twice on the ProStar. But mine was just an inch off of the radiator base plate. I had to cut the zip ties that secured the harness to the frame rail and front crossmember to locate its shape under all of the electrical tape. It only read correctly after the truck had been shut down long enough to cool off, and only in the winter. In the warmer weather it picked up the heat off of the asphalt, and that through it off. Now, it is reading the correct temp.

So on a Volvo what/where would I look to find my sensor?

@mrseas On mine It's on the head light wiring harness that connect the driver and passenger side headlights on the hood in the center.

Thanks.....I'll take a look!

I might be a noob here but where does it display at on the 11 Prostar? I've owned this one and never seen a temp display, thanks
