 Subject: Clogged heater core - ThoroFlush?
IP: Logged
Message:
A couple years ago I lost virtually all heating. My heater core is toast and this was no doubt due to my lame failure to ever flush my coolant. This even contributed to my water pump failing (bearings/seals) at about 8 years (57590 miles).
So - what to do about the clogged heater core? I'm sure many of you know what's involved in removing it from the Dakota so let's not even go there. In exploring/searching/surfing the 'net, I stumbled onto what I believe may be the very next best thing:
Thoro Flush by Irontite (Kwik-way):

According to its manufacturer, this industrial strength product has been successfully used on diesels and heavy duty trucks. The one-pint jar is actually a powder which is mixed on-site to the recommended specs (using very hot water). You then isolate the heater core by cutting/disconnecting the feeder hoses and - with the heater turned ON - circulating the Thoro Flush solution in a back flush direction for about 10 minutes or so. It's supposed to work miracles ...
This may be the only "solution" to this problem, short of the miserable task of removing the core from under the dash.
Has anyone ever heard of/used Thoro Flush?

I just took my truck last weekend to the shop. I always do the repairs my self, except this time, its been so cold around here 20 below cero, so its no way to work on my truck in a garage with no heat. I got replaced the thermostat and I new that the heater core was pluged, got a little heat only going 2000 rpm and ending with a little leak on the tube that goes from the water pump to the heater core. so they put a JB COOLANT CHEMICAL & they let it stay inside of the heater core about an hour. then, they flush it out and a lot of nasty stuff came out and stunk so bad. was a little expensive, but it was worth it. And now I enjoy riding my truck to work every morning even when here hits the low temperatures. I never hear about the thoro flush. but use any chemical product I think all they are the same.
Good Luck!...
