do you need the fan on the A/C radiator

Local mechanics are installing the RN A/C package on my 1994 NAS D-90 with a 300 TDi. They called today to tell me they think the engine fan is big enough so they may not need the fan that comes mounted to the A/C radiator, They are placing the A/C radiator between the aftermarket intercooler and the engine radiator because the kit from RN has hoses that only go that far.
I'm ok with sandwiching the A/C radiator between the two but I'm not sure about leaving off that fan. I already have the D110 grille surround to bump out that area enough for all three - radiators and intercooler - to fit.
Anyone have any thoughts on this.

Clark

I would keep the fan. AC works much better with a fan, plus it should be wired to come on if the engine temp gets too high as well. Most cars the AC is barely (if at all) adequate if the fan is INOP.

Your local thermoking can modify your AC hoses or fab new ones using the fittings for a reasonable price. That will enable you to install it in the most sensible locations. Obviously if its between the rad and intercooler then installing the fan seems difficult.

"Not needing" the fan sounds to me like a half ass excuse. The fan is turned on and off by the trinary switch, so its only on when the system thinks its needed. I think leaving it out would be a bad plan.

I dont like mechanics that make engineering decisions with my money. I'm prepared to experiment and make my own mistakes, but I nevertheless prefer to install things as-designed.

Clarification: "Mechanics" refers to generic mechanics. Specialists like Shane, Pendy, and some others would be authorized to make such decisions on my behalf.

I realized after I posted this question last night that I really didn't like the idea of removing the fan. Both replies said it very well.

Thanks,

Clark.
