im noticing i get the smell of coolant from the vents sometimes and, after hard excelration sometimes it looks like a small amount of steam comes out.. is this the heater core?

 

Hi,

Pressure test the cooling system to locate the leak. If pressure tester is not available, let the engine idle for 15-20 minutes and look for leak. If you do not see any obvious leak, then the heater core may be shot. Also, check the firewall where the heater hoses meet the heatercore inlet & outlet, it may be leaking there in which case you only need new O-rings I believe (someone correct me if I'm wrong).

I hope this gets you started. Keep safety in mind when working on the cooling system, as it's under high-pressure & temperature.

I'd say your diagnosis of the heatercore is correct from the symptoms you're talking about. Do you notice a coolant smell anyother time? Wet carpets?

yes i do notice a coolant smell

 

how hard is it to replace this i know on most cars its a pain

 

Like JPN said, please check the hose connections at the firewall first. It may be something fairly simple as a loose hose.

Everybody seems to be having problems with their heater cores lately.

Hi Glenn, always good to hear from you.

 

Better now before the winter hits...

 

Agreed.

BTW, I like your signature photo, especially the one on the far right. Nice angle & dusk environment.

Hi Redman, what is your question? Are you trying to take it out?
