This viscous heater delete kit I ordered arrived promptly and went together without a hitch. The package is very well put together, A manual comes with it (in color on top of that, a very nice touch) you can tell some serious thought went into it to cover all bases for even the most unfamiliar with wrenching on their jeep. If you still have questions, WWDiesel is quick to answer and will break it down to make it as simple to understand as possible. He's that guy. The one that knows every little thing about the CRD you could possibly want to know. Ask me how i know. lol. Jokes aside though, I would highly recommend this to anyone looking to get rid of that leaky siv that is the viscous heater. It's a better product then what you can find elsewhere out there, and I wouldn't hesitate to do business with him again. And no I'm not trying to stroke any egos. But his input has spanned out on multiple fronts with questions and issues I've come across with this vehicle. N not jus ones revolving around this delete kit he manufactures and sells. That's hard to find these days and really shows a test of his character. So by all means drop the man a DM. I'm sure i'll be bothering him again in the future. You should too. Lol. Jk. Give him a shout, I'm sure he'll get back with ya.

Thanks.

I may be interested in one if I knew what it cost and if anyone who has installed one in a cold climate has any complaints regarding slow warm up.

Sent you a PM.
It eliminates a possible clutch pulley & bearing failure device along with eliminating coolant leaking from the unit. Also removes a HP drag on the engine when the clutch is engaged.
And, the viscous heater is no longer available new by Mopar, it has been discontinued, so the only replacement option is finding a good used unit if it fails. The Viscous Heater does not provide a lot of actual heat input into the cabin heater.
I have sold kits to some customers in the northern states and a few in Canada and so far none have complained of having cabin heat issues.
I reside in the south where the lowest temps we see in winter is in the teens and having NO Viscous Heater has never caused any cabin heat issues. My Jeep's heater heats up very quickly within a mile or two of driving.

Maybe some of those owners in cold climates can respond to your question as they certainly can speak better on the subject than I.

Has anyone replaced the Viscous Heater with a vacuum pump? I'd like to run my vacuum systems with a pump that is outside of the crankcase. Can you imagine getting a leak in your power brake hose or diaphragm and blowing your front main seal?

I have never heard or read of anyone having a failed vacuum pump. (so far)
Can that vacuum pump you shown be use as a air compressor.
A small belt driven air compressor would be very nice to have in place of the Viscous Heater with a switch to engage the clutch when you need on board air. :idea:

WWDiesel,

I was not implying that the internal vacuum pump might fail, I was expressing I'd like to get the vacuum pump's exhaust out of the crankcase. The possible fault might be a failed hose or diaphragm that would allow a large volume of air to get vacuumed into the crankcase -- possibly more than the crankcase ventilation system could handle. The final fault might be another cause of pushing the front main seal out.

In a quest for a failure having the least consequences, I'd rather see the crankcase ventilation oil separator pushed out of the valve cover than the front main seal pushed out of place. I'd rather have a "fail safe" than a "fail catastrophe". Unfortunately the crankcase ventilation oil separator is bolted in, and the front main seal is only pressed is -- probably with some gasket sealer to help glue it in. (I may remove the bolts in the crankcase ventilation oil separator and hold it in with gasket sealer instead of installing an external vacuum pump.)

I do, however, see some practical and handy uses for your idea of a small air compressor in place of the viscous heater. Have you explored that avenue? You could offer those for sale along with your viscous heater replacement idler pulleys.

Dean.

The diesel XJ's (export only) up to about 1998 had a vac pump on the back of the alternator. There are many other diesels like this. The internal vac pump was seen as improvement. My XJ (2000 MY) has the internal one. Never been a problem. Both are vane type vac pumps.
How much blow-by are you seeing?
A part from a vac leak or driving with your left foot resting on the brake peddle, its unlikely that vac pump is the problem. I have seen failed brake booster diaphragms causing vac problems.

layback40,

I'm not sure how much blow by my engine is making, but I just changed the oil 2 weeks ago and the crankcase is already full of jet black oil now. There is a lot of oddness going on and I'm not certain I can blame it all on a kinked breather hose.

When I get this one back on the road I'll have a better idea about the condition of the engine. I know how to check for excessive blow by fumes. This is a newly rebuilt engine with only about 1000 miles on it, so it's possible the rings are still settling in. I'm hoping the bearings survived this mess, but if not, I'll rebuild the other engine and do a swap later.
I've never had to spend so much time on an engine. It's exhausting. :dizzy:

Dean.

If you would like to remove and eliminate your worn out or leaking Viscous Heater and / or plumbing, or you just want to get rid of the VH?
I have developed a viscous heater elimination kit using strong and lightweight billet aluminum bar stock, a Gates idler pulley, and a grade 8 mounting bolt.
Direct bolt on replacement for the viscous heater, uses original VH mounting bolts and reuses stock serpentine belt. No other parts required!
Heater hose rerouting & modification is covered in written install procedures which comes with kit.
I have tested it on my personal vehicle now for a couple of months and it functions perfectly with no issues.

How could I purchase one of these from you?

WWDiesel · **Posted:** Fri May 24, 2024 11:00 pm

Sent you an email with the purchase information.

So that's what that thing is. Thought it was the AC compressor at first glance.

Probably don't need that here in the Arizona Desert.

I'll put the delete on my to do list.

Are kits still available? If so, what is the current pricing?

Thanks.
