I get foggy windows and a significant puddle on the passenger side. Mechanic told me it's a leaking heater core. His quote is too much money to spend on this old 1989.

So, I thought it might be possible to simply take the heater out of the system (I can do without) by brute forcing the heater in/out hoses shut.

Is this a feasible solution?

Thanks!

Hard to feel sorry for a guy who can 'live without' a heater!

A safer bet might be to loop the heater hoses together. That is, bypass the heater core from under the hood. This keeps the cooling system flowing normally (since you're probably in an area that needs cooling capacity). You eliminate any possible leaking from the heater valve too.

Now, shall I start a thread to explain Block Heaters to Theper?

Hey look at this guy, with his sarcastic charm and wit.

I'm good with a sweater... and the electric chair (heating). Thanks for the idea though, that might be exactly what I'm going to do.

Thanks!

Hey, It's below 0c this morning up here. I'll be changing over to snow tires this weekend since I have to be 300km north on Tuesday. A heater will be a necessity for the next 6+ months.

I'm not sarcastic, I'm jealous.

you can bypass the heater. You just gotta be able to plug the send & return hoses in the engine bay. I think the 89 has the latter of the 740 dashes so the heater core isnt that terrible. My 94 940 has an access panel behind the glove box so you can remove the heater core w/o removing the whole dash (i used to work for dodge. Caravan's blew h/c's all the time....the WHOLE thing hadda come out...)
