front mount intercooler cooking my engine

[nissannewby]

You will most likey get a pressure drop across an intercooler as you are making the air more dense and cooling it, when you cool air its pressure reduces and when you heat air the pressure increases.

Can't remember what rad are you running, some out there restrict airflow to much.
even though they may be thicker doesn't always mean better.
Agree,Capacity of rad may be a problem.
high flow water pump may cause problems to, water not in rad long enough to cool.
Have a good look at the seals around all your coolers "air paths" leaks going around the outside can be detrimental.
Even the gap between bonnet and rad support can be a loss.

The W2A was a denco barrel cooler and it leaked green shit into engine so it is gone???

Tip on density vs pressure is good to know. Let's see how the top mount compares hey???

Other question.
Radiator is factory with new td42 top tank and new core. All GU specs.
With a/c fan now back in makes huge difference but it is winter so who knows.

G'day mate,

I don't think you might even consider this but mine is an auto Safari running front mount a2a I/cooler with 2 thermo fans in front of it and a transmission cooler behind it..my ac condenser is on the roof rack. It's not that as practical but my Safari isnt really my daily driver.

I had a similar problem some years ago when I put a V6 Holden motor in a 4Runner. I ended up modifying the radiator to a tripple pass (not hard to do) and putting a Davis Craig electric water pump in series with the mechanical pump. Never had a problem again - and I did some serious off road and towing.

All solved.
Just did 3000 km trip with some 4x4 and no over temp. Tip of day is that the AC fan is absolutely necessary. And there isn't enough space on an auto GU to fit the extra exchanger. Top mount ARE works a treat.
