There’s no point in upgrading the radiator of an E36 if you’re not going to follow it with a high-quality pump. We worked with Pelican Parts in order to acquire an EWP Stewart Components High Performance Water Pump.
The benefit of this water pump comes with 20% more flow, stainless steel impeller and heavy duty bearings. It might cost twice as much as other options but we’re looking at producing twice the power and want to make sure we have no issues with cooling.
To put the finishing touches on our new cooling system we added a SPAL electric fan. The SPAL electric fan will enable us to remove the old fatigued mechanical fan which is also known as a high failure part on the E36 model.
The first installed parts were the HPS hoses. We actually put these on before we did the engine build, way before. During one of our routine systems checks we found the old stock hoses were getting dangerously brittle. We could feel them crinckle in our hands! An issue we would not have to worry about anymore with our new HPS Silicone hoses.
