Hey.

 

I've got a fairly newish radiator sitting in my shed that I want to put onto my KE70. I'm just wondering if a shroud is necessary? I have one on my current radiator but I dunno if I have the knowledge to modify it to fit on the new one.

 

So basically, are shrouds necessary?

 

Cheers.

in perth i would say yes.

 

in melb i drove my ae71 with a blown head gasket for three weeks without a radiator at all. short trips only, was a hell tough car.

 

shroud will help your engine fan draw air throught the radiator at slow speeds like in trraffic.

 

maybe you'd be better reading up on thermofans and fitting a cheap secondhand one that comes with a shroud.

 

uses less horsepower, and cools more efficiently, and only when needed.

Cheers Dave. Will read up on them and seriously consider it.

I found that my car would overheat in traffic before I stuck mine one. That and I had to stick it of for my roadworthy.

Plus its a safety thing.

From an efficiency point of view, if it came with one originally, then fit it. If it didn't, it will work better with a shroud if it is fitted properly.

 

But I'm with Dave, so easy to pick up electric fans cheaply these days with built in shrouds and just use a toyota temp sensor to drive it rather than stuffing around with temp probes in top hoses.

 

The Witzl on toymods has done a great write up on wiring thermo fans with the later type (ie from cars fitted with thermo fans) toyota temp switch as a trigger.

 

All that is aside from any roadworthy, safety issues.

Yeh it will work better for sure.
