Universal Radiator Surge Tank Cap,Coolant Reservoir Cap for Chevy GMC Buick Cadillac Pontiac Saturn -Silverado 1500 2500 3500 Express Avalanche Suburban Captiva Cavalier Cobalt Equinox Malibu

Old cap seemed loose. Ordered this one to replace. Works great

Not for sure what the issue is I just recently had to replace my radiator Reservoir cap on my 2011 Chevy 1500 pickup truck it's barely been on a month and a half went to take the cap off to check my water after it's set overnight and just twisting the cap trying to get it to come loose it broke the top half of the cap off leaving the inner stuck in the neck or the throat of the reservoir bottle so now I'm going to have to pry it basically destroy it to get it out and buy a new radiator cap because I cannot check my water

Excellent fitting it's working good 👍Thank you .At first its felt like it wont fit but after pushing it down and twisting it it work and fit ,seals was was excellent.

I changed a 17 year old radiator cap because my coolant level kept dropping and there were no apparent leaks anywhere. This fixed the problem immediately! Thanks. Good product

Absolute garbage first time I tried to remove it it came apart and I had to pry the other half out of the coolant tank

Product look like it would work, but I purchased the wrong model and had to return it and order the correct one.

Needed a replacement and this fits great!!

This cap saved my family a big expensive car repair bill. It was the fix that was needed for my daughter car and it has been running hot for months until my husband googled what to do and this took care of it. It doesn’t run hot anymore.
