Re: LDC Cooling mod install.

I'm pulling the transmission in the next week or so. Should I do Lethal's cooling mod kit, or D'Agonstinos??

Whatre the benefits/disadvantages to each one?

They both do the same thing, so I'm thinking even though I have the transmission out, an extra $100 in my pocket would be nice.

I like D'Agonstino's kit, but don't want to spend $220. I may just have to bite the bullet and get it. If it saves me an engine then it will be worth it.

Re: LDC Cooling mod install.

Lets say I was doing an eaton swap. Do you think I could install this when my intake and everything is removed to avoid pulling the trans ?

Re: LDC Cooling mod install.

Thats why they made the GEN2 version. So if you bought the GEN2, then yes.

Re: LDC Cooling mod install.

I don't think I've heard of the Gen 2 version. I'll have to find some info on it.

EDIT: I now see the Gen 2 is the lethal one. Is one preferred to the other ? I like that the Gen 2 doesn't require me to pull my trans. I assume it works just as well as the originally posted one ?

Thats what I want to know as well. I assume they essentially do the same thing. I like that the Gen2 costs half as much.

I don't know which one I should buy

Re: LDC Cooling mod install.

Well I went with the GEN1 LDC Cooling mod. Just a word of advice for the next person.

The drivers side freeze plug is cake to take off. I hit it with a punch and hammer and then was able to pull it out with a pair of pliers. Super easy.

The passenger side stock fitting was an absolute PITA. The easiest way to do it I found, was to disconnect the two fittings for the heater on the top of the engine bay near the fire wall. You push the buttons on the side and they come out pretty easy. Next, your going to have to pull the hose off the passenger side fitting. Its one of those annoying heater clamps, in a super tight spot to get to. Hope you have a foot long pair of needle nose pliers, or like me, a long flat head and a lot of patience.

The fitting was BS to get off. It was on there so tight. I used a block of wood against the rear of the engine and a crow bar and after bending the crap out of it, and roating it, and pulling. It finally came out. The directions acted like it was simply grab it and pull it out by hand, ya thats not the case at all. Its so tight of a fit.

..Putting the new parts on was pretty easy though. Just taking off the stock passenger fitting sucked.

Re: LDC Cooling mod install.


I am having a Vortec V-3 installed and the 'LDC' mod won't work because the tee in front of he engine is replaced by the Vortec tee, which is pipe. Would have to break it open and weld on a fitting to attach the hose to. In summary, the head to head cooling mod featured in this thread is the best/only mod with a Vortec supercharger installed. I'm having it added to the build.

Question Re: LDC Cooling mod install.

Which is better? I don't know but I thought about this. The LDC system takes the hotter water from one one water jacket and allows it to travel through the corresponding water jacket on the other side of the engine. The Gen 2 system lets the water from the hotter side go directly up front to the radiator. On it's face it seems the Gen 2 is a better idea.

Re: LDC Cooling mod install.

I think either one is just fine. If I'm going to do one I'll do the "top mounted" kit to save the $$ and get same results. I have seen cobra guys with the "top mount kit" doing fine. So if it's working in their S/C application, it will be fine for my n/A application aka stock lol

thanks for the link.

I cant tell from their site (but will email them)... does the MMR mod just go from the top rear of the driver side hear to same spot on the passenger side head? no splice into the radiator hose??

this setup looks like better quality (AN fitings versus the cheap screw clamps on the mod sold by lethal).

has anyone bought the MMR version??

Re: LDC Cooling mod install.

Should this be done even if not supercharging?

If you drive the car hard, or plan to boost it, I think its a good idea.

If you don't, I wouldn't bother.

Aren't the 04 heads updated to fix the coolant circulation problem?

This is the unit I have on mine. Not needed I just wanted it
Its a very well built piece.


Those fitting are indeed a pain to take off. I use a little grease when re installing. Makes the next removal a bit easier.
