## Description

Hayden Automotive 698 Transmission Oil Cooler

Review: Works amazing for 2018 Subaru Forester - Couldn't be happier. Installation was obviously fairly difficult, but it came with everything I needed to ensure a tight fit. I've been able to tow cross-country, in and out of mountains, in summer, without temperatures becoming concerning even while close to my vehicle's max towing capacity.
Review: Installed on 1999 accord lx f32a4 - I installed this as a additional cooler to the OEM radiator cooler. Ironically.. The cooler holes lined up perfectly with the threaded factory holes for where the two horns are secured. I added one threaded nut insert on the bottom with a piece of EPDM rubber to secure the bottom. It's very solid. I relocated the horns on the sides and extended the wires for the horns with crimp heat shrink butt connector. Cooler itself is very good quality. Has the internal bypass for colder temps. This size is probably overkill for a 4cyl honda but the price difference for the smaller one was only a few dollars. Has 3/8" barb fitting inlet and outlet. I used single ear crimp type clamps instead of screw clamps. I ran this cooler in parallel with oem radiator cooler. So that this cooler is on the return side of the radiator cooler lines. So.. Transmission outlet --> radiator cooler --> Hayden 698 --> transmission inlet.

## Questions & Answers

**Q: Have toyota rav4 v6 2010 will it fit? Tks**
A: If you have doubts, measure out the dimensions of this cooler and make a cardboard cut out of the size. Test fit the physical size in the area you'll be mounting at. Make sure you buy/make some brackets that you'll have to to mount it with.

**Q: If this cooler has a 160 degree bipass, how do you fill it with fluid, do you have to wait until it gets hot and then it drains the oil out the trans?**
A: That’s actually the best way to ensure all the air is out and the fluid is flowing normally

**Q: Is this cooler good enough to bypass the radiator, or this needs to go thru the radiator then to this cooler?**
A: No it's not u must continue threw radiator

**Q: what tempature is the bipass set at and can it be removed?**
A: According to Hayden, bypass valve opens at 160 degrees, and bypass is built in. If you don't need a bypass, order different model that doesn't have one.
