Reservoir starts leaking coolant if fan doesn't run

4 posts in this topic

I have a 1999 626 2.5L, upon the needle reaching the half way point on the interior gauge, is just when the car starts to leak coolant from the reservoir tank. At this point the cooling fan finally kicks in and it no longer leaks coolant out. I can see the coolant go all the way up on the inside of the reservoir and once the fan kicks in after a short while the coolant level drops to the low level. I just had the radiator cleaned also about a year ago I replaced the thermostat and the ect sensor. Any ideas or suggestions. Thanks

It's currently not leaking from the cap nor from a crack in the reservoir but was at one point from the seems. I have used epoxy to seal the seems since then. So now when coolant does overflow it comes out from the pressure release hose on the reservoir.

I would test and check your radiator cap and see if it's holding proper specified pressure. I think it's supposed to be able to 15psi?
