Thru Firewall with Heater Core Lines???

Hello,

I just stumbled across this board for the first time while searching the Internet for info related to a recent install that was performed by a local "pro". Looks like there are some experienced installers here. I hope someone will be able to answer my question.

I have a simple setup in a Toyota RAV4 with a Uniden scanner and fender mounted 5/8 wave VHF whip antenna. The antenna mount consists of the Antenex L-Bracket together with the basic NMO with RG-58A/u coax. While looking the vehicle over today, I noticed that the installer routed the antenna cable through the firewall with one of the coolant lines that go to the heater core. Needless to say, this pipe gets extremely hot when the engine is running. Is the coax in danger of melting?

Thanks

Yes. Change it immediately, if not sooner.

However, are you sure it's a coolant line for the heater core? The A/C system has 2 lines thru the firewall also.

Yes, they are definitely the heater lines. I thought at first they were A/C, but they were easily traceable to the engine block. Final confirmation was provided when I almost burned my fingers off while checking under the dash.

Of course, I'll have to cut the antenna connector off to re-route the cable. This means I'll need a crimping tool to reattach it. Anyone know where to acquire a decent one at a reasonable price? How about those flat metal wiring snakes?

Thanks

Wiring snake?

Look in your closet for the nearest coat hanger you don't want anymore.

Maybe you should have your Local Pro reroute it.
Well, or maybe not.

Or desolder it from the NMO mount and pull it into the inside, and re-run it out a grommet.
