I got the nickname Luke Duke in the middleschool years. Followed me into my paintball career, and we started with the name a hazard to all, and quickly transformed to a hazzard to all, and it stuck to me after that.
I bought a "T" connector and attached all the hoses to it and plugged the vacuum line. My heater and a/c work fine still. I don't know what the point if the HCV is
Supposedly, the purpose of the HCV is to allow the A/C to work better. When the A/C is on max, it short circuits the hot water so that the radiator is not heating up the air ducts and working against cooling the air. But it surely is a sore spot on the Catera.
It's been over 4 years since I did the HCV relocate / modification in my Catera and hasn't gone bad yet. I'm guessing the excessive heat by the rear engine bay area where it used to originally be maybe causing the HCVs to short live, again just a guess and not sure if others had any problem with the mod. Also, if the HCV goes bad, they are very easy to replace, no draining coolant anymore and just use hose pinch pliers to the hoses and swap the HCV.
I did this mod to my in laws 01 catera too and it is holding up too with no problems.
Alright folks, the heater control valve (AC Delco brand) finally gave up today and it has a minor leak coming for the top side. After relocating it (almost 5 years ago) from the back to the front this is the first time I'm having to replace it. It is also a very easy swap since it is in the front, probably 15 minutes at the most.
Thanks elvin315, yeah I'm keeping up with my 98 Catera and so far it has 115K . I had to retighten the oil cooler plate yesterday due to a coolant leak and after the oil cooler replacement I did a month ago from an oil/coolant mix. After installing everything back I noticed the minor leak from the HCV. Anyways, I order another ACDelco part from Amazon and should be here Tuesday.
