Hi Folks,

This past weekend I did a little modification to the heater control valve on my catera. First, the reason I did this is because its a pain to get to it and second, also spending hours to replace it at least every two years. I decided to relocate it for easy access if it goes bad again. I have also attached the links so you can see, let me know what you think. Your opinions are appreciated.

So... my catera takes forever to get good heat.. is that a bad HCV? and should I have it replaced?? the car is going in on monday..

The car is warm after about 10-15min of driving.. but It litterally has to be on for at least 10 min befor it starts getting warm at all.

Hello all,

Just checking again with those that did the Heater control valve modification.....any issues with your car or HCV failing after this mod?

Mine is still running good since I did this mod and haven't had any failure with it, still using the same one.

Keep me posted!!!


Thanks.

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.


Thanks.

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.

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.
