I squeaky in the steering column can be fixed with a simple spray lube.
Unfortunately I can't remember exactly where to spray but I know it fixed mine there was a thread on it but it was a few years back.
As far as parts go I like and use Partsouq.com they have a easy to use web site great...
So to be clear the hose that the arrow points two does not go through the firewall it stops at the firewall and attaches to a hard line that go's through the firewall. Is it the short hose on the engine side of the firewall that's leaking ?
@Malleus did not mean to offend anyone, just don' t want the job to be any harder then it needs to be!!! Were all here to try and help.
We need to know what hose is leaking to be able to help!!!
Cheers
To be clear 91-92 are completely different from the 93-94s
And if you’re going to tackle all the heaters hoses make sure you get a control valve as it well most likely crumble when you try to remove the hose from it.
