i have a smell of coolant in the cab of my 1997 f150 4.6. how should i check the system to see if the heater coil is leaking. no signs of water in cab. where is the heater coil? how hard is it to get to to check around the heater? thanks

 

The heater core is in a box with the AC evaporator. The coolant
is probably leaking out the condensation drain in the bottom of
the box. Has your coolant level been dropping? If you pressurize
the system, you should see coolant on the ground at about the
firewall....good luck!!


Welcome to FTE!!!!!!

 

i was wondering if the access is from under the hood or from inside behind the dash? is this a hard fix? how much do you think labor and materials will cost. thanks again.

 

I'm not sure on the cost but it's a big job.....the whole dash has to come out to replace the core

 

My heater core is letting me know that this winter was it's last. I'll wait until this spring/summer to replace it. If I have to pull the dash, then this baby might as well get the white face gauges while I have everything apart.

 

going to the dealer monday. will pay big because i expect a good warranty. gulp

 

if your heater core is leeakin it will most likely be wet under your passenger side floor mat.bet ya didnt check there.the H.core for my 93 f-10 5.0 was only around $20 at autozone,but from the stealer i wouldnt even want to know lol.you could always go to autozone,buy the haynes manual for your truck and see you think you can do it yourself.it usually gives good enough detail.
